-# Generic Travis CI build script for boostorg repositories
-#
-# Instructions for customizing this script for your library:
-# 
-# 1. Copy the ci/ directory from the same source into your project:
-#    ci/build.sh runs the build
-#    ci/codecov.sh is used to run a profiling build and upload results to codecov.io
-#    ci/coverity.sh is used to run a coverity build and upload results coverity scan
-# 2. Customize the compilers and language levels you want.  Default is C++03.
-# 3. Update the global B2 environment settings to your liking.
-# 4. If you have more than include/, src/, and test/ directories then
-#    add them to the depinst.py line as "--include tools" for tools/ (you
-#    can put multiple --include on the command line).
-# 5. If you want to enable Coverity Scan, you need to provide the environment
-#    variables COVERITY_SCAN_TOKEN and COVERITY_SCAN_NOTIFICATION_EMAIL in
-#    your github settings.
-# 6. Enable pull request builds in your boostorg/<library> account.
-# 7. Change the default C++ version in ci/*.sh (search for CXXSTD)
-#
-# That's it - the scripts will do everything else for you.

-Program Options, part of the collection of [Boost C++ Libraries](http://github.com/boostorg), allows for definition and acquisition of (name, value) pairs from the user via conventional methods such as command line and config file.  It is roughly analogous to getopt_long, but for use with C++.

-CLI (part of the Jarakta project)
-http://jakarta.apache.org/commons/cli/index.html
-
-This is Java library. 
-The interface seems to be similiar, except for data storage.
-1. Instead of variables_map, the library can store the data
-as Java system properties.
-2. The class Option, which uses to describe the data, is also
-   used to keep the value. In contract, I keep them in separate
-   place. This facilitate using the same options description
-   for different data sources.
-
-TODO: Need to check that Option.setType method does.
-
-Werken.opt
-http://sourceforge.net/projects/werken-opt/
-
-This is a much simpler library then CLI, which
-somewhat less features.
-
-JArgs
-http://jargs.sourceforge.net/
-
-Another Java library. Has a fixed set of value types it can
-handle.
-
-Options (by Brad Appleton)
-http://www.enteract.com/~bradapp/ftp/src/libs/C++/Options.html
-
-This is very lean library. It does not provide argument validation,
-and the only iterface is iteration over arguments. An interesting
-iterface decision is using chars to identify presense of option's parameters.
-This may be moved to my library (|, :, ?, *, +)
-
-Cmdline (by Brad Appleton)
-http://www.enteract.com/~bradapp/ftp/src/libs/C++/CmdLine.html
-
-This library provides options validation and storage. Unfortunately
-1. Only a fixed set of data types is supported.
-2. It's intrusive -- one has to declare variable of "class ArgChar" or
-something, and then extract data from there.

-  <title>Changes since formal review</title>
-
-  <para>During formal review, a large number of changes was suggested. To make
-  using the new version easier, the implemented changes are described
-  below.</para>
-
-  <para>Let's start with an example. The following is a typical code for the
-  reviewed version:<programlisting>
-      options_description desc;
-      desc.add_options()           
-          ("magic", parameter&lt;int&gt;("value"), "magic value for the program")
-          .default_value("43")
-
-      variables_map vm;
-      options_and_arguments oa1 = parse_command_line(ac, av, desc);
-      store(oa1, vm, desc)
-
-      variables_map vm2;
-      ifstream ifs("main.cfg");
-      options_and_arguments oa2 = parse_config_file(ifs, desc);
-      store(oa1, vm2, desc);
-
-      vm.next(&amp;vm2);
-    </programlisting>The code for the current version would look like:
-    <programlisting>
-      options_description desc;
-      desc.add_options()           
-          ("magic", value&lt;int&gt;()->default_value(43), 
-                   "magic value for the program")
-
-      variables_map vm;
-
-      store(parse_command_line(ac, av, desc), vm);
-
-      ifstream ifs("main.cfg");
-      store(parse_command_line(ifs, desc), vm);
-
-      notify(vm);
-    </programlisting>
-  </para>
-    
-  <para>Let's examine all the changes in detail</para>
-
-  <section>
-    <title>Option description</title>      
-
-    <itemizedlist>
-      <listitem>
-        <para>The <code>parameter</code> function was renamed to          
-        <code>value</code>. Rationale: "paramater" is yet another term with no
-        clear definition, while "value" is already used everywhere in
-        docs.</para>
-      </listitem>
-      <listitem>
-        <para>The default value is specified in different place, and should
-        use the value of desired type, not string. Previous code was:
-          <programlisting>
-            ("magic", parameter&lt;int&gt;("value")).default_value("43")
-          </programlisting>
-          and the new code is
-          <programlisting>
-            ("magic", parameter&lt;int&gt;("value")->default_value(43));
-          </programlisting>          
-          Rationale: the new way is less restrictive. At the same time, the
-          new design allows to implement other behaviour, like validation of
-          the value, which require knowledge of the value type.         
-        </para>
-      </listitem>
-        
-      <listitem>
-        <para>The number of token value can take on command line, which was
-        specified using character suffix appended to value name, is now
-        specified using more explicit member calls. Moreover, it's not longer
-        possible to specify the "value name".
-          For example:
-<programlisting>("numbers", parameter&lt;int&gt;("n+"))</programlisting>
-          has became
-<programlisting>("numbers", value&lt;int&gt;()->multitoken())</programlisting>
-          Rationale: such modifiers tend to make command line usage less
-        clear. There's no need to make evil things too easy to do.
-          The "value name" had only two roles: specifying modifiers, and
-        telling what to output in automated help. The first role has became
-        obsolete, and the second was questionable too. It was very unclear how
-        to decide on the best "value name", and eventually the selection was randon.

-    <title>Unicode Support</title>
-
-    <para>Unicode support was one of the features specifically requested
-      during the formal review. Throughout this document "Unicode support" is
-      a synonym for "wchar_t" support, assuming that "wchar_t" always uses
-      Unicode encoding.  Also, when talking about "ascii" (in lowercase) we'll
-      not mean strict 7-bit ASCII encoding, but rather "char" strings in local
-      8-bit encoding.
-    </para>
-
-    <para>
-      Generally, &quot;Unicode support&quot; can mean
-      many things, but for the program_options library it means that:
-
-      <itemizedlist>
-        <listitem>
-          <para>Each parser should accept either <code>char*</code>
-          or <code>wchar_t*</code>, correctly split the input into option
-          names and option values and return the data.
-          </para>
-        </listitem>
-        <listitem>
-          <para>For each option, it should be possible to specify whether the conversion
-            from string to value uses ascii or Unicode.
-          </para>
-        </listitem>
-        <listitem>
-          <para>The library guarantees that:
-            <itemizedlist>
-              <listitem>
-                <para>ascii input is passed to an ascii value without change
-                </para>
-              </listitem>
-              <listitem>
-                <para>Unicode input is passed to a Unicode value without change</para>
-              </listitem>
-              <listitem>
-                <para>ascii input passed to a Unicode value, and Unicode input
-                  passed to an ascii value will be converted using a codecvt
-                  facet (which may be specified by the user).
-                </para>
-              </listitem>
-            </itemizedlist>
-          </para>
-        </listitem>
-      </itemizedlist>
-    </para>
-
-    <para>The important point is that it's possible to have some "ascii
-      options" together with "Unicode options". There are two reasons for
-      this. First, for a given type you might not have the code to extract the
-      value from Unicode string and it's not good to require that such code be written.
-      Second, imagine a reusable library which has some options and exposes
-      options description in its interface. If <emphasis>all</emphasis>
-      options are either ascii or Unicode, and the library does not use any
-      Unicode strings, then the author is likely to use ascii options, making
-      the library unusable inside Unicode
-      applications. Essentially, it would be necessary to provide two versions
-      of the library -- ascii and Unicode.
-    </para>
-
-    <para>Another important point is that ascii strings are passed through
-      without modification. In other words, it's not possible to just convert
-      ascii to Unicode and process the Unicode further. The problem is that the
-      default conversion mechanism -- the <code>codecvt</code> facet -- might
-      not work with 8-bit input without additional setup.
-    </para>
-
-    <para>The Unicode support outlined above is not complete. For example, we
-      don't support Unicode option names. Unicode support is hard and
-      requires a Boost-wide solution. Even comparing two arbitrary Unicode
-      strings is non-trivial. Finally, using Unicode in option names is
-      related to internationalization, which has its own
-      complexities. E.g. if option names depend on current locale, then all
-      program parts and other parts which use the name must be
-      internationalized too.
-    </para>
-
-    <para>The primary question in implementing the Unicode support is whether
-      to use templates and <code>std::basic_string</code> or to use some
-      internal encoding and convert between internal and external encodings on
-      the interface boundaries.
-    </para>
-
-    <para>The choice, mostly, is between code size and execution
-      speed. A templated solution would either link library code into every
-      application that uses the library (thereby making shared library
-      impossible), or provide explicit instantiations in the shared library
-      (increasing its size). The solution based on internal encoding would
-      necessarily make conversions in a number of places and will be somewhat slower.
-      Since speed is generally not an issue for this library, the second
-      solution looks more attractive, but we'll take a closer look at
-      individual components.
-    </para>
-
-    <para>For the parsers component, we have three choices:
-      <itemizedlist>
-        <listitem>
-          <para>Use a fully templated implementation: given a string of a
-            certain type, a parser will return a &parsed_options; instance
-            with strings of the same type (i.e. the &parsed_options; class
-            will be templated).</para>
-        </listitem>
-        <listitem>
-          <para>Use internal encoding: same as above, but strings will be converted to and
-            from the internal encoding.</para>
-        </listitem>
-        <listitem>
-          <para>Use and partly expose the internal encoding: same as above,
-            but the strings in the &parsed_options; instance will be in the
-            internal encoding. This might avoid a conversion if
-            &parsed_options; instance is passed directly to other components,
-            but can be also dangerous or confusing for a user.
-          </para>
-        </listitem>
-      </itemizedlist>
-    </para>
-
-    <para>The second solution appears to be the best -- it does not increase
-    the code size much and is cleaner than the third. To avoid extra
-    conversions, the Unicode version of &parsed_options; can also store
-    strings in internal encoding.
-    </para>
-
-    <para>For the options descriptions component, we don't have much
-      choice. Since it's not desirable to have either all options use ascii or all
-      of them use Unicode, but rather have some ascii and some Unicode options, the
-      interface of the &value_semantic; must work with both. The only way is
-      to pass an additional flag telling if strings use ascii or internal encoding.
-      The instance of &value_semantic; can then convert into some
-      other encoding if needed.
-    </para>
-
-    <para>For the storage component, the only affected function is &store;.
-      For Unicode input, the &store; function should convert the value to the
-      internal encoding.  It should also inform the &value_semantic; class
-      about the used encoding.
-    </para>
-
-    <para>Finally, what internal encoding should we use? The
-    alternatives are:
-    <code>std::wstring</code> (using UCS-4 encoding) and
-    <code>std::string</code> (using UTF-8 encoding). The difference between
-    alternatives is:
-      <itemizedlist>
-        <listitem>
-          <para>Speed: UTF-8 is a bit slower</para>
-        </listitem>
-        <listitem>
-          <para>Space: UTF-8 takes less space when input is ascii</para>
-        </listitem>
-        <listitem>
-          <para>Code size: UTF-8 requires additional conversion code. However,
-            it allows one to use existing parsers without converting them to
-            <code>std::wstring</code> and such conversion is likely to create a
-            number of new instantiations.
-          </para>
-        </listitem>
-
-      </itemizedlist>
-      There's no clear leader, but the last point seems important, so UTF-8
-      will be used.
-    </para>
-
-    <para>Choosing the UTF-8 encoding allows the use of existing parsers,
-      because 7-bit ascii characters retain their values in UTF-8,
-      so searching for 7-bit strings is simple. However, there are
-      two subtle issues:
-      <itemizedlist>
-        <listitem>
-          <para>We need to assume the character literals use ascii encoding
-          and that inputs use Unicode encoding.</para>
-        </listitem>
-        <listitem>
-          <para>A Unicode character (say '=') can be followed by 'composing
-          character' and the combination is not the same as just '=', so a
-          simple search for '=' might find the wrong character.
-          </para>
-        </listitem>
-      </itemizedlist>
-      Neither of these issues appear to be critical in practice, since ascii is
-      almost universal encoding and since composing characters following '=' (and
-      other characters with special meaning to the library) are not likely to appear.
-    </para>

-    <title>Non-conventional Syntax</title>
-
-    <para>Sometimes, standard command line syntaxes are not enough. For
-    example, the gcc compiler has "-frtti" and "-fno-rtti" options, and this
-    syntax is not directly supported.
-    </para>
-
-    <indexterm><primary>additional parser</primary></indexterm>
-    <para>For such cases, the library allows the user to provide an
-    <firstterm>additional parser</firstterm> -- a function which will be called on each
-    command line element, before any processing by the library. If the
-    additional parser recognises the syntax, it returns the option name and
-    value, which are used directly. The above example can be handled by the
-    following code:
-    </para>
-
-    <para>
-      <programlisting>
-pair&lt;string, string&gt; reg_foo(const string&amp; s)
-{
-    if (s.find("-f") == 0) {
-        if (s.substr(2, 3) == "no-")
-            return make_pair(s.substr(5), string("false"));
-        else
-            return make_pair(s.substr(2), string("true"));
-    } else {
-        return make_pair(string(), string());
-    }
-}
-</programlisting>
-      Here's the definition of the additional parser. When parsing the command
-      line, we pass the additional parser:
-<programlisting>
-store(command_line_parser(ac, av).options(desc).extra_parser(reg_foo)
-        .run(), vm);
-</programlisting>
-      The complete example can be found in the "example/custom_syntax.cpp"
-      file.
-    </para>
-  </section>
-
-  <section>
-    <title>Response Files</title>
-
-    <indexterm><primary>response files</primary></indexterm>
-
-    <para>Some operating systems have very low limits of the command line
-      length. The common way to work around those limitations is using
-      <firstterm>response files</firstterm>.  A response file is just a
-      configuration file which uses the same syntax as the command line. If
-      the command line specifies a name of response file to use, it's loaded
-      and parsed in addition to the command line.  The library does not
-      provide direct support for response files, so you'll need to write some
-      extra code.
-    </para>
-
-    <para>
-      First, you need to define an option for the response file:
-<programlisting>
-("response-file", value&lt;string&gt;(),
-     "can be specified with '@name', too")
-</programlisting>
-    </para>
-
-    <para>Second, you'll need an additional parser to support the standard syntax
-    for specifying response files: "@file":
-<programlisting><![CDATA[
-pair<string, string> at_option_parser(string const&s)
-{
-    if ('@' == s[0])
-        return std::make_pair(string("response-file"), s.substr(1));
-    else
-        return pair<string, string>();
-}
-]]>
-</programlisting>
-    </para>
-
-    <para>Finally, when the "response-file" option is found, you'll have to
-    load that file and pass it to the command line parser. This part is the
-    hardest. We'll use the Boost.Tokenizer library, which works but has some
-    limitations. You might also consider Boost.StringAlgo. The code is:
-<programlisting><![CDATA[
-if (vm.count("response-file")) {
-     // Load the file and tokenize it
-     ifstream ifs(vm["response-file"].as<string>().c_str());
-     if (!ifs) {
-         cout << "Could not open the response file\n";
-         return 1;
-     }
-     // Read the whole file into a string
-     stringstream ss;
-     ss << ifs.rdbuf();
-     // Split the file content
-     char_separator<char> sep(" \n\r");
-     std::string ResponsefileContents( ss.str() );
-     tokenizer<char_separator<char> > tok(ResponsefileContents, sep);
-     vector<string> args;
-     copy(tok.begin(), tok.end(), back_inserter(args));
-     // Parse the file and store the options
-     store(command_line_parser(args).options(desc).run(), vm);
-}
-]]>
-</programlisting>
-      The complete example can be found in the "example/response_file.cpp"
-      file.

-  <section>
-    <title>Winmain Command Line</title>
-
-    <para>On the Windows operating system, GUI applications receive the
-    command line as a single string, not split into elements. For that reason,
-    the command line parser cannot be used directly. At least on some
-    compilers, it is possible to obtain
-    the split command line, but it's not clear if all compilers support the
-    same mechanism on all versions of the operating system. The
-    <code>split_winmain</code> function is a portable mechanism provided
-    by the library.</para>
-
-    <para>Here's an example of use:
-<programlisting>
-vector&lt;string&gt; args = split_winmain(lpCmdLine);
-store(command_line_parser(args).options(desc).run(), vm);
-</programlisting>
-      The <code>split_winmain</code> function is overloaded for <code>wchar_t</code> strings, so can
-      also be used in Unicode applications.
-    </para>

-  <section>
-    <title>Option Groups and Hidden Options</title>
-
-    <para>Having a single instance of the &options_description; class with all
-    the program's options can be problematic:
-      <itemizedlist>
-        <listitem>
-          <para>Some options make sense only for specific source, for example,
-          configuration files.</para>
-        </listitem>
-        <listitem>
-          <para>The user would prefer some structure in the generated help message.</para>
-        </listitem>
-        <listitem>
-          <para>Some options shouldn't appear in the generated help message at all.</para>
-        </listitem>
-      </itemizedlist>
-    </para>
-
-    <para>To solve the above issues, the library allows a programmer to create several
-      instances of the &options_description; class, which can be merged in
-      different combinations. The following example will define three groups of
-      options: command line specific, and two options group for specific program
-      modules, only one of which is shown in the generated help message.
-    </para>
-
-    <para>Each group is defined using standard syntax. However, you should
-      use reasonable names for each &options_description; instance:
-<programlisting><![CDATA[
-options_description general("General options");
-general.add_options()
-    ("help", "produce a help message")
-    ("help-module", value<string>(),
-        "produce a help for a given module")
-    ("version", "output the version number")
-    ;
-
-options_description gui("GUI options");
-gui.add_options()
-    ("display", value<string>(), "display to use")
-    ;
-
-options_description backend("Backend options");
-backend.add_options()
-    ("num-threads", value<int>(), "the initial number of threads")
-    ;
-]]></programlisting>
-    </para>
-
-    <para>After declaring options groups, we merge them in two
-      combinations. The first will include all options and be used for parsing. The
-      second will be used for the "--help" option.
-<programlisting>
-// Declare an options description instance which will include
-// all the options
-options_description all("Allowed options");
-all.add(general).add(gui).add(backend);
-
-// Declare an options description instance which will be shown
-// to the user
-options_description visible("Allowed options");
-visible.add(general).add(gui);
-</programlisting>
-    </para>
-
-    <para>What is left is to parse and handle the options:
-<programlisting><![CDATA[

-    return 0;
-}
-if (vm.count("help-module")) {
-    const string& s = vm["help-module"].as<string>();
-    if (s == "gui") {
-        cout << gui;

-      When parsing the command line, all options are allowed. The "--help"
-      message, however, does not include the "Backend options" group -- the
-      options in that group are hidden. The user can explicitly force the
-      display of that options group by passing "--help-module backend"
-      option. The complete example can be found in the
-      "example/option_groups.cpp" file.

-    <title>Custom Validators</title>
-
-    <para>By default, the conversion of option's value from string into C++
-      type is done using iostreams, which sometimes is not convenient. The
-      library allows the user to customize the conversion for specific
-      classes. In order to do so, the user should provide suitable overload of
-      the <code>validate</code> function.
-    </para>
-
-    <para>
-      Let's first define a simple class:
-<programlisting><![CDATA[
-struct magic_number {
-public:
-    magic_number(int n) : n(n) {}
-    int n;
-};
-]]></programlisting> and then overload the <code>validate</code> function:
-<programlisting><![CDATA[
-void validate(boost::any& v,
-              const std::vector<std::string>& values,
-              magic_number* target_type, int)
-{
-    static regex r("\\d\\d\\d-(\\d\\d\\d)");
-
-    using namespace boost::program_options;
-
-    // Make sure no previous assignment to 'a' was made.
-    validators::check_first_occurrence(v);
-    // Extract the first string from 'values'. If there is more than
-    // one string, it's an error, and exception will be thrown.
-    const string& s = validators::get_single_string(values);
-
-    // Do regex match and convert the interesting part to
-    // int.
-    smatch match;
-    if (regex_match(s, match, r)) {
-        v = any(magic_number(lexical_cast<int>(match[1])));
-    } else {
-        throw validation_error(validation_error::invalid_option_value);
-    }
-}
-]]>
-</programlisting>The function takes four parameters. The first is the storage
-      for the value, and in this case is either empty or contains an instance of
-      the <code>magic_number</code> class. The second is the list of strings
-      found in the next occurrence of the option. The remaining two parameters
-      are needed to work around the lack of partial template specialization and
-      partial function template ordering on some compilers.
-    </para>
-
-    <para>The function first checks that we don't try to assign to the same
-      option twice. Then it checks that only a single string was passed
-      in. Next the string is verified with the help of the Boost.Regex
-      library. If that test is passed, the parsed value is stored into the
-      <code>v</code> variable.
-    </para>
-
-    <para>The complete example can be found in the "example/regex.cpp" file.
-    </para>

-  <section>
-    <title>Unicode Support</title>
-
-    <para>To use the library with Unicode, you'd need to:
-      <itemizedlist>
-        <listitem>
-          <para>Use Unicode-aware parsers for Unicode input</para>
-        </listitem>
-        <listitem>
-          <para>Require Unicode support for options which need it</para>
-        </listitem>
-      </itemizedlist>
-    </para>
-
-    <para>Most of the parsers have Unicode versions. For example, the
-      &parse_command_line; function has an overload which takes
-      <code>wchar_t</code> strings, instead of ordinary <code>char</code>.
-    </para>
-
-    <para>Even if some of the parsers are Unicode-aware, it does not mean you
-    need to change definition of all the options. In fact, for many options,
-    like integer ones, it makes no sense. To make use of Unicode you'll need
-    <emphasis>some</emphasis> Unicode-aware options. They are different from
-    ordinary options in that they accept <code>wstring</code> input, and
-    process it using wide character streams. Creating an Unicode-aware option
-    is easy: just use the <code>wvalue</code> function instead of the
-    regular <code>value</code>.
-    </para>
-
-    <para>When an ascii parser passes data to an ascii option, or a Unicode
-      parser passes data to a Unicode option, the data are not changed at
-      all. So, the ascii option will see a string in local 8-bit encoding, and
-      the Unicode option will see whatever string was passed as the Unicode
-      input.
-    </para>
-
-    <para>What happens when Unicode data is passed to an ascii option, and
-      vice versa? The library automatically performs the conversion from
-      Unicode to local 8-bit encoding. For example, if command line is in
-      ascii, but you use <code>wstring</code> options, then the ascii input
-      will be converted into Unicode.
-    </para>
-
-    <para>To perform the conversion, the library uses the <code>codecvt&lt;wchar_t,
-    char&gt;</code> locale facet from the global locale. If
-    you want to work with strings that use local 8-bit encoding (as opposed to
-    7-bit ascii subset), your application should start with:
-      <programlisting>
-locale::global(locale(""));
-      </programlisting>
-      which would set up the conversion facet according to the user's selected
-      locale.
-    </para>
-
-    <para>It's wise to check the status of the C++ locale support on your
-      implementation, though. The quick test involves three steps:
-      <orderedlist>
-        <listitem>
-          <para>Go to the "test" directory and build the "test_convert" binary.</para>
-        </listitem>
-        <listitem>
-          <para>Set some non-ascii locale in the environment. On Linux, one can
-          run, for example: <screen>
-$ export LC_CTYPE=ru_RU.KOI8-R
-</screen>
-          </para>
-        </listitem>
-        <listitem>
-          <para>Run the "test_convert" binary with any non-ascii string in the
-            selected encoding as its parameter. If you see a list of Unicode codepoints,
-            everything's OK. Otherwise, locale support on your system might be
-            broken.</para>
-        </listitem>
-      </orderedlist>
-    </para>
-
-    </section>
-
-    <section>
-      <title>Allowing Unknown Options</title>
-
-      <para>Usually, the library throws an exception on unknown option names. This
-      behaviour can be changed. For example, only some part of your application uses
-      <libraryname>Program_options</libraryname>, and you wish to pass unrecognized options to another part of
-      the program, or even to another application.</para>
-
-      <para>To allow unregistered options on the command line, you need to use
-      the &basic_command_line_parser; class for parsing (not &parse_command_line;)
-      and call the <methodname alt="boost::program_options::basic_command_line_parser::allow_unregistered">allow_unregistered</methodname>
-      method of that class:
-      <programlisting>
-parsed_options parsed =
-    command_line_parser(argc, argv).options(desc).allow_unregistered().run();
-      </programlisting>
-
-      For each token that looks like an option, but does not have a known name,
-      an instance of &basic_option; will be added to the result.
-      The <code>string_key</code> and <code>value</code> fields of the instance will contain results
-      of syntactic parsing of the token, the <code>unregistered</code> field will be set to <code>true</code>,
-      and the <code>original_tokens</code> field will contain the token as it appeared on the command line.
-      </para>
-
-      <para>If you want to pass the unrecognized options further, the
-      <functionname alt="boost::program_options::collect_unrecognized">collect_unrecognized</functionname> function can be used.
-      The function will collect original tokens for all unrecognized values, and optionally, all found positional options.
-      Say, if your code handles a few options, but does not handle positional options at all, you can use the function like this:
-      <programlisting>
-vector&lt;string&gt; to_pass_further = collect_unrecognized(parsed.options, include_positional);
-      </programlisting>
-
-      </para>
-
-    </section>
-
-    <section>
-      <title>Testing Option Presence</title>
-
-      <para>Until now we have tested whether an option has been set using the
-      <methodname alt="boost::program_options::variables_map::count">count</methodname> method on the &variables_map;
-      class; as you are repeating the (string literal) name of the option this is prone to typos and/or errors
-      resulting from renaming the option in one place but not the other:
-        <programlisting><![CDATA[
-po::options_description desc("Allowed options");
-desc.add_options()
-    ("compression", po::value<int>(), "set compression level")
-;
-
-po::variables_map vm;
-po::store(po::parse_command_line(ac, av, desc), vm);
-po::notify(vm);
-
-if (vm.count("compression")) {
-    cout << "Compression level was set to "
- << vm["compression"].as<int>() << ".\n";
-} else {
-    cout << "Compression level was not set.\n";
-}
-]]>
-        </programlisting>
-      </para>
-
-      <para>Instead, you can use a variable of type <classname alt="boost::optional">boost::optional</classname>;
-      <libraryname>Program_options</libraryname> provides special support for <libraryname>Boost.Optional</libraryname>
-      such that if the user specifies the option the <classname alt="boost::optional">boost::optional</classname>
-      variable will be initialized to the appropriate value:
-        <programlisting><![CDATA[
-po::options_description desc("Allowed options");
-boost::optional<int> compression;
-desc.add_options()
-    ("compression", po::value(&compression), "set compression level")
-;
-
-po::variables_map vm;
-po::store(po::parse_command_line(ac, av, desc), vm);
-po::notify(vm);
-
-if (compression) {
-    cout << "Compression level was set to " << *compression << ".\n";
-} else {
-    cout << "Compression level was not set.\n";

-  <title>Library Overview</title>
-
-  <para>In the tutorial section, we saw several examples of library usage.
-    Here we will describe the overall library design including the primary
-    components and their function.
-  </para>
-
-  <para>The library has three main components:
-    <itemizedlist>
-      <listitem>
-        <para>The options description component, which describes the allowed options
-          and what to do with the values of the options.
-        </para>
-      </listitem>
-      <listitem>
-        <para>The parsers component, which uses this information to find option names
-          and values in the input sources and return them.
-        </para>
-      </listitem>
-      <listitem>
-        <para>The storage component, which provides the
-          interface to access the value of an option. It also converts the string
-          representation of values that parsers return into desired C++ types.
-        </para>
-      </listitem>
-    </itemizedlist>
-  </para>
-
-  <para>To be a little more concrete, the <code>options_description</code>
-  class is from the options description component, the
-  <code>parse_command_line</code> function is from the parsers component, and the
-  <code>variables_map</code> class is from the storage component. </para>
-
-  <para>In the tutorial we've learned how those components can be used by the
-    <code>main</code> function to parse the command line and config
-    file. Before going into the details of each component, a few notes about
-    the world outside of <code>main</code>.
-  </para>
-
-  <para>
-    For that outside world, the storage component is the most important. It
-    provides a class which stores all option values and that class can be
-    freely passed around your program to modules which need access to the
-    options. All the other components can be used only in the place where
-    the actual parsing is done.  However, it might also make sense for the
-    individual program modules to describe their options and pass them to the
-    main module, which will merge all options. Of course, this is only
-    important when the number of options is large and declaring them in one
-    place becomes troublesome.
-  </para>
-
-<!--
-  <para>The design looks very simple and straight-forward, but it is worth
-  noting some important points:
-    <itemizedlist>
-      <listitem>
-        <para>The options description is not tied to specific source. Once
-        options are described, all parsers can use that description.</para>
-      </listitem>
-      <listitem>
-        <para>The parsers are intended to be fairly dumb. They just
-          split the input into (name, value) pairs, using strings to represent
-          names and values. No meaningful processing of values is done.
-        </para>
-      </listitem>
-      <listitem>
-        <para>The storage component is focused on storing options values. It
-        </para>

-
-  <section>
-    <title>Options Description Component</title>
-
-    <para>The options description component has three main classes:
-      &option_description;, &value_semantic; and &options_description;. The
-      first two together describe a single option. The &option_description;
-      class contains the option's name, description and a pointer to &value_semantic;,
-      which, in turn, knows the type of the option's value and can parse the value,
-      apply the default value, and so on. The &options_description; class is a
-      container for instances of &option_description;.
-    </para>
-
-    <para>For almost every library, those classes could be created in a
-      conventional way: that is, you'd create new options using constructors and
-      then call the <code>add</code> method of &options_description;. However,
-      that's overly verbose for declaring 20 or 30 options. This concern led
-      to creation of the syntax that you've already seen:
-<programlisting>
-options_description desc;
-desc.add_options()
-    ("help", "produce help")
-    ("optimization", value&lt;int&gt;()->default_value(10), "optimization level")
-    ;
-</programlisting>
-    </para>
-
-    <para>The call to the <code>value</code> function creates an instance of
-      a class derived from the <code>value_semantic</code> class: <code>typed_value</code>.
-      That class contains the code to parse
-      values of a specific type, and contains a number of methods which can be
-      called by the user to specify additional information. (This
-      essentially emulates named parameters of the constructor.) Calls to
-      <code>operator()</code> on the object returned by <code>add_options</code>
-      forward arguments to the constructor of the <code>option_description</code>
-      class and add the new instance.
-    </para>
-
-    <para>
-      Note that in addition to the
-      <code>value</code>, library provides the <code>bool_switch</code>
-      function, and user can write his own function which will return
-      other subclasses of <code>value_semantic</code> with
-      different behaviour. For the remainder of this section, we'll talk only
-      about the <code>value</code> function.
-    </para>
-
-    <para>The information about an option is divided into syntactic and
-      semantic. Syntactic information includes the name of the option and the
-      number of tokens which can be used to specify the value. This
-      information is used by parsers to group tokens into (name, value) pairs,
-      where value is just a vector of strings
-      (<code>std::vector&lt;std::string&gt;</code>). The semantic layer
-      is responsible for converting the value of the option into more usable C++
-      types.
-    </para>
-
-    <para>This separation is an important part of library design. The parsers
-      use only the syntactic layer, which takes away some of the freedom to
-      use overly complex structures. For example, it's not easy to parse
-      syntax like: <screen>calc --expression=1 + 2/3</screen> because it's not
-      possible to parse <screen>1 + 2/3</screen> without knowing that it's a C
-      expression. With a little help from the user the task becomes trivial,
-      and the syntax clear: <screen>calc --expression="1 + 2/3"</screen>
-    </para>
-
-    <section>
-      <title>Syntactic Information</title>
-      <para>The syntactic information is provided by the
-        <classname>boost::program_options::options_description</classname> class
-        and some methods of the
-        <classname>boost::program_options::value_semantic</classname> class
-        and includes:
-        <itemizedlist>
-          <listitem>
-            <para>
-              name of the option, used to identify the option inside the
-              program,
-            </para>
-          </listitem>
-          <listitem>
-            <para>
-              description of the option, which can be presented to the user,
-            </para>
-          </listitem>
-          <listitem>
-            <para>
-              the allowed number of source tokens that comprise options's
-              value, which is used during parsing.
-            </para>
-          </listitem>
-        </itemizedlist>
-      </para>
-
-      <para>Consider the following example:
-      <programlisting>
-options_description desc;
-desc.add_options()
-    ("help", "produce help message")
-    ("compression", value&lt;string&gt;(), "compression level")
-    ("verbose", value&lt;string&gt;()->implicit_value("0"), "verbosity level")
-    ("email", value&lt;string&gt;()->multitoken(), "email to send to")
-    ;
-      </programlisting>
-      For the first option, we specify only the name and the
-      description. No value can be specified in the parsed source.
-      For the second option, the user must specify a value, using a single
-      token. For the third option, the user may either provide a single token
-      for the value, or no token at all. For the last option, the value can
-      span several tokens. For example, the following command line is OK:
-      <screen>
-          test --help --compression 10 --verbose --email beadle@mars beadle2@mars
-      </screen>
-      </para>
-
-      <section>
-        <title>Description formatting</title>
-
-        <para>
-          Sometimes the description can get rather long, for example, when
-          several option's values need separate documentation. Below we
-          describe some simple formatting mechanisms you can use.
-        </para>
-
-        <para>The description string has one or more paragraphs, separated by
-        the newline character ('\n'). When an option is output, the library
-        will compute the indentation for options's description. Each of the
-        paragraph is output as a separate line with that indentation. If
-        a paragraph does not fit on one line it is spanned over multiple
-        lines (which will have the same indentation).
-        </para>
-
-        <para>You may specify additional indent for the first specified by
-        inserting spaces at the beginning of a paragraph. For example:
-        <programlisting>
-options.add_options()
-    ("help", "   A long help msg a long help msg a long help msg a long help
-msg a long help msg a long help msg a long help msg a long help msg ")
-    ;
-        </programlisting>
-        will specify a four-space indent for the first line. The output will
-        look like:
-        <screen>
-  --help                    A long help msg a long
-                        help msg a long help msg
-                        a long help msg a long
-                        help msg a long help msg
-                        a long help msg a long
-                        help msg
-
-        </screen>
-        </para>

-        <para>For the case where line is wrapped, you can want an additional
-        indent for wrapped text. This can be done by
-        inserting a tabulator character ('\t') at the desired position. For
-        example:
-        <programlisting>
-options.add_options()
-      ("well_formated", "As you can see this is a very well formatted
-option description.\n"
-                        "You can do this for example:\n\n"
-                        "Values:\n"
-                        "  Value1: \tdoes this and that, bla bla bla bla
-bla bla bla bla bla bla bla bla bla bla bla\n"
-                        "  Value2: \tdoes something else, bla bla bla bla
-bla bla bla bla bla bla bla bla bla bla bla\n\n"
-                        "    This paragraph has a first line indent only,
-bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla");
-        </programlisting>
-        will produce:
-        <screen>
-  --well_formated       As you can see this is a
-                        very well formatted
-                        option description.
-                        You can do this for
-                        example:
-
-                        Values:
-                          Value1: does this and

-                                  bla
-                          Value2: does something
-                                  else, bla bla
-                                  bla bla bla bla

-                            This paragraph has a

-        The tab character is removed before output. Only one tabulator per

-      <title>Semantic Information</title>
-
-      <para>The semantic information is completely provided by the
-        <classname>boost::program_options::value_semantic</classname> class. For
-        example:
-<programlisting>
-options_description desc;
-desc.add_options()
-    ("compression", value&lt;int&gt;()->default_value(10), "compression level")
-    ("email", value&lt; vector&lt;string&gt; &gt;()
-        ->composing()->notifier(&amp;your_function), "email")
-    ;
-</programlisting>
-        These declarations specify that default value of the first option is 10,
-        that the second option can appear several times and all instances should
-        be merged, and that after parsing is done, the library will  call
-        function <code>&amp;your_function</code>, passing the value of the

-      <title>Positional Options</title>
-
-      <para>Our definition of option as (name, value) pairs is simple and
-        useful, but in one special case of the command line, there's a
-        problem. A command line can include a <firstterm>positional option</firstterm>,
-        which does not specify any name at all, for example:
-        <screen>
-          archiver --compression=9 /etc/passwd
-        </screen>
-        Here, the "/etc/passwd" element does not have any option name.
-      </para>
-
-      <para>One solution is to ask the user to extract positional options
-        himself and process them as he likes. However, there's a nicer approach
-        -- provide a method to automatically assign the names for positional
-        options, so that the above command line can be interpreted the same way
-        as:
-        <screen>
-          archiver --compression=9 --input-file=/etc/passwd
-        </screen>
-      </para>
-
-      <para>The &positional_options_desc; class allows the command line
-        parser to assign the names. The class specifies how many positional options
-        are allowed, and for each allowed option, specifies the name. For example:
-<programlisting>
-positional_options_description pd; pd.add("input-file", 1);
-</programlisting> specifies that for exactly one, first, positional
-        option the name will be "input-file".
-      </para>
-
-      <para>It's possible to specify that a number, or even all positional options, be
-        given the same name.
-<programlisting>
-positional_options_description pd;
-pd.add("output-file", 2).add("input-file", -1);
-</programlisting>
-        In the above example, the first two positional options will be associated
-        with name "output-file", and any others with the name "input-file".
-      </para>
-
-    <warning>
-      <para>The &positional_options_desc; class only specifies translation from
-      position to name, and the option name should still be registered with
-      an instance of the &options_description; class.</para>

-    <title>Parsers Component</title>
-
-    <para>The parsers component splits input sources into (name, value) pairs.
-      Each parser looks for possible options and consults the options
-      description component to determine if the option is known and how its value
-      is specified. In the simplest case, the name is explicitly specified,
-      which allows the library to decide if such option is known. If it is known, the
-      &value_semantic; instance determines how the value is specified. (If
-      it is not known, an exception is thrown.) Common
-      cases are when the value is explicitly specified by the user, and when
-      the value cannot be specified by the user, but the presence of the
-      option implies some value (for example, <code>true</code>). So, the
-      parser checks that the value is specified when needed and not specified
-      when not needed, and returns new (name, value) pair.
-    </para>
-
-    <para>
-      To invoke a parser you typically call a function, passing the options
-      description and command line or config file or something else.
-      The results of parsing are returned as an instance of the &parsed_options;
-      class. Typically, that object is passed directly to the storage
-      component. However, it also can be used directly, or undergo some additional
-      processing.
-    </para>
-
-    <para>
-      There are three exceptions to the above model -- all related to
-      traditional usage of the command line. While they require some support
-      from the options description component, the additional complexity is
-      tolerable.
-      <itemizedlist>
-        <listitem>
-          <para>The name specified on the command line may be
-            different from the option name -- it's common to provide a "short option
-            name" alias to a longer name. It's also common to allow an abbreviated name
-            to be specified on the command line.
-          </para>
-        </listitem>
-        <listitem>
-          <para>Sometimes it's desirable to specify value as several
-          tokens. For example, an option "--email-recipient" may be followed
-          by several emails, each as a separate command line token. This
-          behaviour is supported, though it can lead to parsing ambiguities
-          and is not enabled by default.
-          </para>

-        <listitem>
-          <para>The command line may contain positional options -- elements
-            which don't have any name. The command line parser provides a

-            tutorial.

-notify(vm);
-</programlisting>
-      The <code>variables_map</code> class is used to store the option

-
-    <para>The priority is handled in a simple way: the <code>store</code>

-      <title>Environment variables parser</title>
-
-      <para><firstterm>Environment variables</firstterm> are string variables
-      which are available to all programs via the <code>getenv</code> function
-      of C runtime library. The operating system allows to set initial values
-      for a given user, and the values can be further changed on the command
-      line.  For example, on Windows one can use the
-      <filename>autoexec.bat</filename> file or (on recent versions) the
-      <filename>Control Panel/System/Advanced/Environment Variables</filename>
-      dialog, and on Unix &#x2014;, the <filename>/etc/profile</filename>,
-      <filename>~/.profile</filename> and <filename>~/.bash_profile</filename>
-      files. Because environment variables can be set for the entire system,
-      they are particularly suitable for options which apply to all programs.
-      </para>
-
-      <para>The environment variables can be parsed with the
-      &parse_environment; function. The function has several overloaded
-      versions. The first parameter is always an &options_description;
-      instance, and the second specifies what variables must be processed, and
-      what option names must correspond to it. To describe the second
-      parameter we need to consider naming conventions for environment
-      variables.</para>
-
-      <para>If you have an option that should be specified via environment
-      variable, you need to make up the variable's name. To avoid name clashes,
-      we suggest that you use a sufficiently unique prefix for environment
-      variables. Also, while option names are most likely in lower case,
-      environment variables conventionally use upper case. So, for an option
-      name <literal>proxy</literal> the environment variable might be called
-      <envar>BOOST_PROXY</envar>. During parsing, we need to perform reverse
-      conversion of the names. This is accomplished by passing the chosen
-      prefix as the second parameter of the &parse_environment; function.
-      Say, if you pass <literal>BOOST_</literal> as the prefix, and there are
-      two variables, <envar>CVSROOT</envar> and <envar>BOOST_PROXY</envar>, the
-      first variable will be ignored, and the second one will be converted to
-      option <literal>proxy</literal>.
-      </para>
-
-      <para>The above logic is sufficient in many cases, but it is also
-      possible to pass, as the second parameter of the &parse_environment;
-      function, any function taking a <code>std::string</code> and returning
-      <code>std::string</code>. That function will be called for each
-      environment variable and should return either the name of the option, or
-      empty string if the variable should be ignored. An example showing this
-      method can be found in "example/env_options.cpp".
-      </para>

-  <section>
-    <title>Types</title>
-
-    <para>Everything that is passed in on the command line, as an environmental
-    variable, or in a config file is a string. For values that need to be used
-    as a non-string type, the value in the variables_map will attempt to 
-    convert it to the correct type.</para>
-
-    <para>Integers and floating point values are converted using Boost's 
-    lexical_cast. It will accept integer values such as "41" or "-42". It will
-    accept floating point numbers such as "51.1", "-52.1", "53.1234567890" (as
-    a double), "54", "55.", ".56", "57.1e5", "58.1E5", ".591e5", "60.1e-5", 
-    "-61.1e5", "-62.1e-5", etc. Unfortunately, hex, octal, and binary
-    representations that are available in C++ literals are not supported by
-    lexical_cast, and thus will not work with program_options.</para>
-
-    <para>Booleans are special in that there are multiple ways to come at them. 
-    Similar to another value type, it can be specified as <code>("my-option",
-    value&lt;bool&gt;())</code>, and then set as:</para>
-    <screen>
-example --my-option=true
-    </screen>
-    <para>However, more typical is that boolean values are set by the simple
-    presence of a switch. This is enabled by &bool_switch; as in <code>
-    ("other-option", bool_switch())</code>. This will cause the value to
-    default to false and it will become true if the switch is found:</para>
-    <screen>
-example --other-switch
-    </screen>
-    <para>When a boolean does take a parameter, there are several options. 
-    Those that evaluate to true in C++ are: "true", "yes", "on", "1". Those
-    that evaluate to false in C++ are: "false", "no", "off", "0". In addition,
-    when reading from a config file, the option name with an equal sign and no
-    value after it will also evaluate to true.</para>

-1. (done)
-   Simplify and clarify interface.
-   
-   It turns out that most users are interested in 'variables_map' class, so
-   it must be possible to use it directly, without even knowing about
-   'options_and_arguments'. The proposed interface is:
-
-   options_description desc;
-   ....
-   variables_map vm;
-   load_from_command_line(vm, desc, argc, argv);
-
-2. (done)
-   Better separation of syntaxic and semantic processing, as suggested by
-   Pavol Droba. 
-
-   The problem with current 'option_description' interface is that the
-   'validator' and 'notifier' callbacks are not really usable by ordinary
-   users --- it's extender's interface. The current 'parameter' function uses
-   those callback to provide user-friendly semantic interface, but it's not
-   documented nor completely worked out.
-
-   In the new interface, the second parameter of 'option_description' ctor
-   will have two possibilities: just a string and a pointer to a new class
-   'value_descriptor'. When passed the latter, it will invoke the instance on
-   itself, and then delete the object. A function 'value' will be provided,
-   that will create value specific for a type.
-
-   Example
-       ("magic", value<int>("n", &n)->default_value(10), "magic value").
-
-   The 'value' function will create instances of 'typed_value_descriptor'
-   type, with the following methods:
-       - default_value
-       - interpreter
-       - validator
-       - notifier
-
-   The 'option_description' class we'll have two attributes to support
-   semantic operation: 'generator', which will handle conversion from string
-   into value (including application of default value), and 'notifier'. Similiar
-   to the the current design, those attributes will be set by
-   'value_descriptor' instances.
-   
-   Another function, "bool_switch" will create value descriptor for type bool,
-   with default value of false. The function is needed to avoid special-casing
-   'value' function on bool type, which was considered confusing (Neal D. Becker).
-
-3. (done) Support for positional options. 
-
-   Positional options will be treated uniformly with ordinary ones. User will
-   be able to specify that, for example, third positional option is to be
-   interpreted as option "output-file" with the same value.
-
-   The user interface will be simple: user will provide two instanes of
-   'options_description' to functions which parse command line. For example.
-
-   options_description desc;
-   desc.add_options()
-   ("magic", "n", "magic value")
-   ;
-
-   options_description pdesc;
-   pdesc.add_options()
-   ("output-file", "n", "output file")
-   ("input-files*", value< vector<string> >("n"), "files")
-   ;
-
-   variables_map vm;
-   load_from_command_line(vm, desc, pdesc, argc, argv);
-
-4. (done, except for registry) 
-   Multiple sources improvement.
- 
-   Need to implement support for registry/environment.
-   Also, must devise a way to handle different naming of option in
-   sources. Lastly, the storing of values into program variables should
-   become part of 'variables_map' interface.
-
-5. Improve documentation.
-
-   Chuck Messenger:
-   "When code is given for an example program, after the code, give examples of
-   using the program, along with the expected output."
-
-   Pavol Droba:
-    "I would prefer a few chapters explaining various components of the
-    library, each followed by a reference."
-
-    Pavel Vozenilek:
-    > Documentation should contain list of compilers the library works on and
-    > also info whether MSVC 6 port is feasible or not.
-    >
-    > The non-Doxygen part of documentation can be also a bit expanded: e.g. I
-    > would welcome some high level overview of the algorithms and structures and
-    > info about expected CPU/memory consumption.
-    >
-    > Also info whether there are any internal limits (like option length) .
-    >
-    > Some examples may be bit more annotated, also contain what is expected
-    > output.
-
-    Syntax highligting.
-
-    Document "*" in option names 
-    Automated tests for examples?
-    (new) Comments inside code snippets?
-    (new) Table of all symbols
-
-
-6. (deferred) 
-   Unicode support
-
-   - unicode in argv/argc
-   - Unicode in config files not supported
-    (
-       The difference between ASCII and unicode files is:
-         - big endian UTF16 starts with 2 bytes FE FF 9mandatory by Unicode
-        standard) - little endian UTF16 starts with FF FE
-          - UTF8 text starts with EF BB BF
-
-        Pavel Vozenilek
-     )
-
-7. Config file improvements
-
-   - should have "allow_unregistered" for config_file.
-   - (done) bool options in config file do not work.
-   - "#" inside strings, in config files (Pavel Vozenilek)
-
-8. 
-   Cmdline improvements
-
-   - must be able to parse WinMain string
-   - support for response files
-
-9. Other changes.
-
-   - (outdated) get_value -> value (Beman)
-   - (done) is "argv" const in std, or not? Adjust docs if not.

-   - (important) what if the same option has different definitions?
-   - (new) We lost the ability to specify options_description instance
-     in call to 'store'. So now we can't store just subset of options.
-     Is it a problem?
-   - (new) Improve formatting of 'arg'.   
-   - (new) revive real and regexp examples.
-   - (new) even more simpler syntax for assignent to var?

-/** @mainpage Program options documentation 
-
-    @section scope Scope
-
-    Briefly, the library should allow program developers to obtain
-    <em>program options</em>, i.e. (name,value) pairs from the user,
-    via conventional methods such as command line and config file.
-    
-    Necessary facilities include:
-    - parse command line
-    - parse config files
-    - perform semantic validation on input, such as checking for correct
-      type of parameters, and storing values.
-    - combine all inputs together, so that all program options can
-      be obtained in one place.
-
-    @section goals Goals
-    The fundamental goals for this library were:
-    - it should be more convenient to use it than parse command line by hand,
-      even when the number of possible options is 2,
-    - all popular command line styles should be supported,
-    - "you pay for what you use" principle is important: simple utilities
-      need not be forced to depend on excessive amount of code.
-    - it must be possible to validate option values, convert them to required
-      types, and store either in program variables, or in data structures
-      maintained by the library.
-    - data from command line and config file should be usable together, and
-      alternative program option sources (such as registry) should be
-      possible.
-
-   @section design_overview Design overview
-
-   To meet the stated goals, the library uses a layered architecture.
-   -# At the bottom, there are two parser classes, 
-      boost::program_options::cmdline and 
-      boost::program_options::config_file.
-    They are responsible for syntax matters only and provide simple 
-    iterator-like interface.
-   -# The boost::program_options::options_and_arguments holds the result of parsing command line or
-    config file. It is still concerned with syntax only and holds precisely
-    what is found on command line. There's a couple of associated parse
-    functions (
-    @ref parse_cmdline_func "1",
-    @ref parse_config_file_func "2"), 
-    which relieve the user from the need to iterate over options 
-    and arguments manually.
-   -# The class boost::program_options::options_description is a high-level 
-    description of allowed
-    program options, which does not depend on concrete parser class. In
-    addition, it can be used to provide help message. There are parse
-    functions which return options_and_arguments given options_description.
-   -# The options_description class also has semantic responsibilities. It's
-    possible to specify validators for option, their default values, and the 
-    like. There's a function boost::program_options::perform_semantic_actions, 
-    which handles this information and returns a map of option values.
-   -# Finally, at the top, there boost::program_options::variables_map class. 
-    It's possible to
-    store options in it, and obtain them later. Another feature is that
-    different variable_map instances can be linked together, so that both
-    command line and config file data is used. Additional option sources can
-    be added at this level.
-

-/** @page rationale Rationale
-
-    @section code_size Focus on code size
-
-    The program options library has two important properties:
-    - runtime performance is not important. After all, command line processing
-      is done only once, and the amount of data is small.
-    - code size matters. Since parsing command line is utility task, users
-    won't be glad to have lots of code linked to every binary which has
-    options.
-    
-    For the above reasons, the the library is designed so that it can be easily
-    used as shared library, with minimum code on the side of main application.
-    In particular, templates are used only where necessary, for example for 
-    validation of user-defined types. In other places, boost::function is
-    used to allow customization, but keep templates out of the public
-    interface.
-
-    @section string_vs_enums Strings vs. enums
-
-    In some places, the library uses strings to convey information that
-    could be represented by enumerations or values. For example, 
-    the program_options::option_description class allows to add "?" to the
-    parameter name to specify that the parameter is optional. For another
-    example, while program_options::cmdline class allows to obtain the
-    index of option, it does not require to specify an index for each option,
-    and it's possible to tell options by their names.
-
-    Such interface appears to be much more usable. If we were using
-    enumeration for different properties of parameter, there would be 
-    another argument to many functions, the need to type long, possible
-    qualified names, and little advantage. 
-
-    That little advantage is that if you type a wrong enumeration name,
-    you'd get a compile error. If you type '!' instead of '?' after parameter
-    name, you'd get incorrect behaviour.  However, such errors are deemed
-    rare.
-
-    @section char_vs_string const char* vs. std::string
-
-    Most of the interface uses const char* where std::string seems a natural 
-    choice. The reason is that those functions are called many times: for
-    example to declare all options. They are typically called with string
-    literals, and implicit conversion to string appears to take a lot of
-    code space. Providing both std::string and const char* version would
-    considerably bloat the interface. Since passing std::string is considered
-    rare, only const char* versions are provided.
-
-    @section init_syntax Initialization syntax
-
-    The syntax used for creating options_description instance was designed to 
-    be as easy as possible in the most common case. Consider:
-    @code
-    desc.add_options()
-            ("verbose", "", "verbosity level")
-            ("magic", "int", "magic value").notify(some_func)
-            ;
-    @endcode
-    Here, most common properties of options: name, presense of parameter and
-    description, are specified very concisely, and additional properties can
-    be given quite naturally, too.
-
-    Another possibility would be:
-    @code
-        option_description d1(...), d2(...);
-        desc.add(d1 & d2);
-    @endcode
-    or         
-    @code
-        option_description d1(...), d2(...);
-        desc = d1, d2;
-    @endcode
-
-    The drawback is the need to explicitly create new objects and give names
-    to them. The latter problem can be helped if objects are created inside
-    expressions:
-    @code
-        desc = option_description(...), option_description(...)
-    @endcode
-    but there's still extra typing.    
-
-    @section help_handling Handling of --help
-
-    It was suggested by Gennadiy Rozental that occurrence of <tt>--help</tt>
-    on command line results in throwing an exception. Actually, the 
-    &quot;special&quot; option must have been configurable. This was not 
-    implemented, because applications might reasonable want to process
-    the rest of command line even of <tt>--help</tt> was seen. For example,
-    <tt>--verbose</tt> option can control how much help should be output, 
-    or there may be several subcommand with different help screens.

-
-    Here, we'll give solution for some desires which seem common.
-
-    @section recipe_parameter_validation How to check for correct option value types and assign them?
-
-    There's the boost::program_options::parameter function. It

-    to boost::program_options::option_description constructor,
-    establishes correct validation routine. A simple example

-    designed to be very lightweight. 
-
-    Anyway, there's a version of the parse_command_line function
-    which does not take an options_description instance. Also, the
-    cmdline class ctor accepts an 'allow_unregistered' parameter. 
-    In both cases, all options will be allowed, and treated as if
-    they have optional parameter.
-
-    Note that with the default style, 
-    @verbatim
-    --foo bar
-    @endverbatim
-    will be taken as option "foo" with value "bar", which is
-    probably not correct. You should disable option parameter in
-    the next token to avoid problems.
-
-    @sa boost::program_options::cmdline
-
-    @section recipe_multiple_modules I have several separate modules which must controlled by options. What am I to do?
-
-    There are several solutions. 
-
-    @subsection sb1 Everything's global
-
-    You can create a single instance of the <tt>options_description</tt> class
-    somewhere near <tt>main</tt>. All the modules will export their own
-    options using other <tt>options_description</tt> instances which can
-    be added to the main one. After that, you'd parse command line and 
-    config files. The parsing results will be stored in one variables_map,
-    which will be passed to all modules, which can work with their own 
-    options.
-
-    @subsection sb2 Private option data
-
-    Assume one of the modules does not like to see irrelevant options.
-    For example, it outputs a configuration file for other program, and
-    irrelevant options will confuse that program. 
-
-    It's possible to give the module only the options that it has
-    registered. First, the module provides an options_description instance
-    which is added to the global one. Second the command line is parsed
-    to produce an options_and_arguments instance. Lastly, the <tt>store</tt>
-    function is called. If passed the options_description instance previously
-    returned by the module, it will store only options specified in that
-    instance. 
-    @sa @ref multiple_modules
-    
-
-    @subsection sb3 Unique option names
-
-    The most general solution would be to give unique names to options
-    for different modules. One module will declare option "module1.server",
-    and another would declare "module2.internal_checks". Of course, there
-    can be global options like "verbosity", declared by <tt>main</tt> and
-    used by all modules.
-
-    This solution avoids all possible name clashes between modules. On
-    the other hand, longer option names can be less user-friendly. This
-    problem can be alleviated if module prefix is used only for less 
-    common option, needed for fine-tuning.

-
-Privet, Volodya.
-
-Here what I am looking for to be supported by Command Line Argument 
-Framework directly or by means of easy extension:
-
-1. command line argument formats
-  a. -<one letter key> <value>
-  b. -<one letter key><value>
-  c. -<key> <value>
-  d. -<option> - any length
-  e. /<key> <value> - and all other cases like a,b,c but with / 
-instead
-  g. --<key> <value>
-  h. -<key substring> <value>
-    An example: let say you expecting argument -osagent_port
-    then following argument lists should be valid:
-       -o 15000
-       -osa 15000
-       -osagent_port 15000
-    On the other hand it should perform validity checks. For example
-    if you also expect another argument -osagent_host. then first 2
-    argument list above should generate runtime error and 3d should
-    pass. Arguments integrity check should also be performed, i.e. 
-    you should not allow for user to define 2 argument like this:
-     "-port"
-     "-port_type"
-
-2. argument types
-   I should be able to explicitle specify expected argument type. For 
-example: std::string, int, double, option(bool). The framework should 
-perform value validation. For example 1.23 is not valid for int 
-argument. The framework should allow to use user-defined classes as 
-expected types for command-line argument. In other word. If I provide 
-you a class with predefined psecification framework should try to 
-generate object of argument class. Some simple extention you can 
-provide youself. For example, using following command line you should 
-be able to generate std::list<int>
-     -values 2 5 7 8
-and using following command line you should be able to generate 
-std::list<std::string>
-     -files_to_test test1.td test2.td test3.td test4.td
-and using following command line user should be able to provide 
-argument class A to generate std::list<A>
-struct A{
-std::string key;
-int         value;
-};
-
--parameters_mapping name1 4 name5 7 name6 8 name9 1123
-
-3. argument storage.
-  a. Framework should be able to generate and store arguments 
-internally. In this case framework in responsable for memory.
-  b. Framework should be able to generate and store argument into the 
-user-bound location. In this case user in responsable for memory.
-
-4. arguments can have default values
-
-5. arguments can be optional and required. The framework should 
-automatically check presence of of all required arguments.
-
-6. argument value access
-  a. if user passed storage location - he will be able to get value 
-from there
-  b. by name and type. If any of them is incorrect - error. The same 
-rules aplied here as in 1.h if argument matching algorithm allows 
-substrings.
-  c. is_present check - to be able to check presence of optional 
-arguments.
-
-7. usage line.
-  The framework should be able to generate a using line given a 
-difinition of all feilds. To support this you will probably need 
-argument description as one of the command line argument 
-constructor's argument. Thr framework should be able to configured to 
-use different usage line. If command line contain predefined keyword 
-(-help or /? for example) framework should print usage message.
-
-8. Framework Error
-  If any of the following condition occures during command line 
-processing the framework should generate an error and print a usage 
-line:
-   a. invalid aargument
-   b. ambiguous argument
-   c. invalid value for the argument
-   d. absence of required argument
-   e. framework meet -help (of any other predefined keyword)
-
-Invalid name or type should generate exception during value access.
-
-Here my view on the problem.
-
-Regards,
-
-Gennadiy.
-
-
-P.S. Did you look into Brat Appleton's work? It seems to be close to 
-what you are doing.

-  <title>Tutorial</title>
-  
-  <para>In this section, we'll take a look at the most common usage scenarios
-  of the program_options library, starting with the simplest one. The examples
-  show only the interesting code parts, but the complete programs can be found
-  in the "BOOST_ROOT/libs/program_options/example" directory. Through all the
-  examples, we'll assume that the following namespace alias is in effect:
-<programlisting>namespace po = boost::program_options;</programlisting>
-  </para>
-
-  <section>
-    <title>Getting Started</title>
-
-  <para>The first example is the simplest possible: it only handles two
-    options. Here's the source code (the full program is in
-    "example/first.cpp"):
-
-<programlisting>
-// Declare the supported options.
-po::options_description desc(&quot;Allowed options&quot;);
-desc.add_options()
-    (&quot;help&quot;, &quot;produce help message&quot;)
-    (&quot;compression&quot;, po::value&lt;int&gt;(), &quot;set compression level&quot;)
-;
-
-po::variables_map vm;
-po::store(po::parse_command_line(ac, av, desc), vm);
-po::notify(vm);    
-
-if (vm.count(&quot;help&quot;)) {
-    cout &lt;&lt; desc &lt;&lt; &quot;\n&quot;;
-    return 1;
-}
-
-if (vm.count(&quot;compression&quot;)) {
-    cout &lt;&lt; &quot;Compression level was set to &quot; 
- &lt;&lt; vm[&quot;compression&quot;].as&lt;int&gt;() &lt;&lt; &quot;.\n&quot;;
-} else {
-    cout &lt;&lt; &quot;Compression level was not set.\n&quot;;
-}
-</programlisting>
-  </para>
-
-  <para>We start by declaring all allowed options using the
-    &options_description; class. The <code>add_options</code> method of that
-    class returns a special proxy object that defines
-    <code>operator()</code>. Calls to that operator actually declare
-    options. The parameters are option name, information about value, and option
-    description. In this example, the first option has no value, and the second
-    one has a value of type <code>int</code>.
-  </para>
-  
-  <para>After that, an object of class <code>variables_map</code> is
-    declared. That class is intended to store values of options, and can store
-    values of arbitrary types. Next, the calls to <code>store</code>,
-    <code>parse_command_line</code> and <code>notify</code> functions cause
-    <code>vm</code> to contain all the options found on the command
-    line.</para>
-
-  <para>And now, finally, we can use the options as we like. The
-    <code>variables_map</code> class can be used just like
-    <code>std::map</code>, except that values stored there must be retrieved
-    with the <code>as</code> method shown above. (If the type specified in the
-    call to the <code>as</code> method is different from the actually stored
-    type, an exception is thrown.)
-  </para>
-
-  <para>It's now a good time to try compiling the code yourself, but if
-    you're not yet ready, here's an example session:
-<screen>
-$ <userinput>bin/gcc/debug/first</userinput>
-Compression level was not set.
-$ <userinput>bin/gcc/debug/first --help</userinput>
-Allowed options:
-  --help                 : produce help message
-  --compression arg      : set compression level
-$ <userinput>bin/gcc/debug/first --compression 10</userinput>
-Compression level was set to 10.

-    <title>Option Details</title>
-    
-  <para>An option value, surely, can have other types than <code>int</code>, and
-  can have other interesting properties, which we'll discuss right now. The
-  complete version of the code snipped below can be found in
-  <filename>example/options_description.cpp</filename>.</para>
-
-  <para>Imagine we're writing a compiler. It should take the optimization
-    level, a number of include paths, and a number of input files, and perform some
-    interesting work. Let's describe the options:
-    <programlisting>
-int opt;
-po::options_description desc(&quot;Allowed options&quot;);
-desc.add_options()
-    (&quot;help&quot;, &quot;produce help message&quot;)
-    (&quot;optimization&quot;, po::value&lt;int&gt;(&amp;opt)-&gt;default_value(10), 
-  &quot;optimization level&quot;)
-    (&quot;include-path,I&quot;, po::value&lt; vector&lt;string&gt; &gt;(), 
-  &quot;include path&quot;)
-    (&quot;input-file&quot;, po::value&lt; vector&lt;string&gt; &gt;(), &quot;input file&quot;)
-;
-</programlisting>
-  </para>
-
-  <para>The <literal>"help"</literal> option should be familiar from 
-  the previous example. It's a good idea to have this option in all cases.
-  </para>
-
-  <para>The <literal>"optimization"</literal> option shows two new features. First, we specify
-    the address of the variable(<code>&amp;opt</code>). After storing values, that
-    variable will have the value of the option. Second, we specify a default
-    value of 10, which will be used if no value is specified by the user.
-  </para>
-
-  <para>The <literal>"include-path"</literal> option is an example of the 
-  only case where the interface of the <code>options_description</code> 
-  class serves only one
-    source -- the command line. Users typically like to use short option names
-    for common options, and the "include-path,I" name specifies that short
-    option name is "I". So, both "--include-path" and "-I" can be used.
-  </para>
-
-  <para>Note also that the type of the <literal>"include-path"</literal>
-  option is <type>std::vector</type>. The library provides special 
-  support for vectors -- it will be possible to specify the option several 
-  times, and all specified values will be collected in one vector.  
-  </para>
-    
-  <para>The "input-file" option specifies the list of files to
-    process. That's okay for a start, but, of course, writing something like:
-    <screen>
-<userinput>compiler --input-file=a.cpp</userinput>
-    </screen>
-    is a little non-standard, compared with
-    <screen>
-<userinput>compiler a.cpp</userinput>
-    </screen>
-    We'll address this in a moment.
-  </para>
-
-  <para>
-    The command line tokens which have no option name, as above, are
-    called "positional options" by this library. They can be handled
-    too. With a little help from the user, the library can decide that "a.cpp"
-    really means the same as "--input-file=a.cpp". Here's the additional code
-    we need:
-    <programlisting>
-po::positional_options_description p;
-p.add(&quot;input-file&quot;, -1);
-
-po::variables_map vm;
-po::store(po::command_line_parser(ac, av).
-          options(desc).positional(p).run(), vm);
-po::notify(vm);
-    </programlisting>    
-  </para>
-
-  <para>
-    The first two lines say that all positional options should be translated
-    into "input-file" options. Also note that we use the
-    &command_line_parser; class to parse the command
-    line, not the &parse_command_line;
-    function. The latter is a convenient wrapper for simple cases, but now we
-    need to pass additional information.
-  </para>
-
-  <para>By now, all options are described and parsed. We'll save ourselves the
-      trouble of implementing the rest of the compiler logic and only print the
-      options:
-    <programlisting>
-if (vm.count(&quot;include-path&quot;))
-{
-    cout &lt;&lt; &quot;Include paths are: &quot; 
-         &lt;&lt; vm[&quot;include-path&quot;].as&lt; vector&lt;string&gt; &gt;() &lt;&lt; &quot;\n&quot;;
-}
-
-if (vm.count(&quot;input-file&quot;))
-{
-    cout &lt;&lt; &quot;Input files are: &quot; 
-         &lt;&lt; vm[&quot;input-file&quot;].as&lt; vector&lt;string&gt; &gt;() &lt;&lt; &quot;\n&quot;;
-}
-
-cout &lt;&lt; &quot;Optimization level is &quot; &lt;&lt; opt &lt;&lt; &quot;\n&quot;;                
-</programlisting>
-  </para>
-
-  <para>Here's an example session:
-    <screen>
-$ <userinput>bin/gcc/debug/options_description --help</userinput>
-Usage: options_description [options]
-Allowed options:
-  --help                 : produce help message
-  --optimization arg     : optimization level
-  -I [ --include-path ] arg : include path
-  --input-file arg       : input file
-$ <userinput>bin/gcc/debug/options_description</userinput>
-Optimization level is 10
-$ <userinput>bin/gcc/debug/options_description --optimization 4 -I foo -I another/path --include-path third/include/path a.cpp b.cpp</userinput>
-Include paths are: foo another/path third/include/path
-Input files are: a.cpp b.cpp
-Optimization level is 4
-</screen>
-  </para>
-
-  <para>
-    Oops, there's a slight problem. It's still possible to specify the
-    "--input-file" option, and usage message says so, which can be confusing
-    for the user. It would be nice to hide this information, but let's wait
-    for the next example.
-  </para>

-    <title>Multiple Sources</title>
-
-    <para>It's quite likely that specifying all options to our compiler on the
-    command line will annoy users. What if a user installs a new library and
-    wants to always pass an additional command line element? What if he has
-    made some choices which should be applied on every run? It's desirable to
-    create a config file with common settings which will be used together with
-    the command line.
-    </para>
-
-    <para>Of course, there will be a need to combine the values from command
-    line and config file. For example, the optimization level specified on the
-    command line should override the value from the config file. On the other
-    hand, include paths should be combined.
-    </para>
-
-    <para>Let's see the code now. The complete program is in
-      "examples/multiple_sources.cpp". The option definition has two interesting
-      details. First, we declare several instances of the
-      <code>options_description</code> class. The reason is that, in general,
-      not all options are alike. Some options, like "input-file" above, should
-      not be presented in an automatic help message. Some options make sense only
-      in the config file. Finally, it's nice to have some structure in the help message,
-      not just a long list of options. Let's declare several option groups:
-      <programlisting>
-// Declare a group of options that will be 
-// allowed only on command line
-po::options_description generic(&quot;Generic options&quot;);
-generic.add_options()
-    (&quot;version,v&quot;, &quot;print version string&quot;)
-    (&quot;help&quot;, &quot;produce help message&quot;)    
-    ;
-    
-// Declare a group of options that will be 
-// allowed both on command line and in
-// config file
-po::options_description config(&quot;Configuration&quot;);
-config.add_options()
-    (&quot;optimization&quot;, po::value&lt;int&gt;(&amp;opt)-&gt;default_value(10), 
-          &quot;optimization level&quot;)
-    (&quot;include-path,I&quot;, 
-         po::value&lt; vector&lt;string&gt; &gt;()-&gt;composing(), 
-         &quot;include path&quot;)
-    ;
-
-// Hidden options, will be allowed both on command line and
-// in config file, but will not be shown to the user.
-po::options_description hidden(&quot;Hidden options&quot;);
-hidden.add_options()
-    (&quot;input-file&quot;, po::value&lt; vector&lt;string&gt; &gt;(), &quot;input file&quot;)
-    ;        
-</programlisting>
-      Note the call to the <code>composing</code> method in the declaration of the
-      "include-path" option. It tells the library that values from different sources
-      should be composed together, as we'll see shortly.
-    </para>
-
-    <para>    
-      The <code>add</code> method of the <code>options_description</code>
-      class can be used to further group the options:
-      <programlisting>
-po::options_description cmdline_options;
-cmdline_options.add(generic).add(config).add(hidden);
-
-po::options_description config_file_options;
-config_file_options.add(config).add(hidden);
-
-po::options_description visible(&quot;Allowed options&quot;);
-visible.add(generic).add(config);
-      </programlisting>
-    </para>
-
-    <para>The parsing and storing of values follows the usual pattern, except that
-      we additionally call <functionname>parse_config_file</functionname>, and
-      call the &store; function twice. But what
-      happens if the same value is specified both on the command line and in
-      config file? Usually, the value stored first is preferred. This is what
-      happens for the "--optimization" option. For "composing" options, like
-      "include-file", the values are merged.
-    </para>
-
-    <para>Here's an example session:
-<screen>
-$ <userinput>bin/gcc/debug/multiple_sources</userinput>
-Include paths are: /opt
-Optimization level is 1
-$ <userinput>bin/gcc/debug/multiple_sources --help</userinput>
-Allows options:
-
-Generic options:
-  -v [ --version ]       : print version string
-  --help                 : produce help message
-
-Configuration:
-  --optimization n       : optimization level
-  -I [ --include-path ] path : include path
-
-$ <userinput>bin/gcc/debug/multiple_sources --optimization=4 -I foo a.cpp b.cpp</userinput>
-Include paths are: foo /opt
-Input files are: a.cpp b.cpp
-Optimization level is 4
-</screen>
-      The first invocation uses values from the configuration file. The second
-      invocation also uses values from command line. As we see, the include
-      paths on the command line and in the configuration file are merged,
-      while optimization is taken from the command line.

-Full Usage Examples
-===================
-
-These were run on windows, so some results may show that environment, but 
-results should be similar on POSIX platforms.
-
-Help
-----
-To see the help screen, with the available options just pass the --help (or -h) 
-parameter. The program will then exit.
-
-    > example.exe --help
-    Program Options Example
-    Usage: example [OPTION]... MASTER-FILE [FILE]...
-      or   example [OPTION] --run-gui
-
-      -h [ --help ]              display this help message
-      -v [ --version ]           show program version
-      -c [ --config ] arg        config files to parse (always parses default.cfg)
-
-      --path arg                 the execution path to use (imports from
-                                 environment if not specified)
-      --verbosity arg (=INFO)    set verbosity: DEBUG, INFO, WARN, ERROR, FATAL
-      -I [ --include-path ] arg  paths to search for include files
-      --run-gui                  start the GUI
-
-Version is similar to help (--version or -v).
-
-    > example.exe -v
-    Program Options Example 1.0
-
-Basics
-------
-Running without any options will get the default values (path is set from the 
-environment):
-
-    > example.exe 
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: INFO
-    Include Path:
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-We can easily override that environment path with a simple option:
-
-    > example.exe --path a/b/c;d/e/f
-    First 75 chars of the system path:
-    a/b/c;d/e/f
-    Verbosity: INFO
-    Include Path:
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-You can use a space or equals sign after long options, also backslashes are
-treated literally on windows, on POSIX they need to be escaped.
-
-    > example.exe --path=a\b\c\;d\e\\f
-    First 75 chars of the system path:
-    a\b\c\;d\e\\f
-    Verbosity: INFO
-    Include Path:
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-For short options you can use a space:
-
-    > example.exe -I path/to/includes
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: INFO
-    Include Path:
-        path\to\includes
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-Or you can put the option immediately after it:
-
-    > example.exe -Ipath/to/includes
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: INFO
-    Include Path:
-        path\to\includes
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-The include path (--include-path or -I) option allows for multiple paths to be 
-specified (both on the command line and in config files) and combined into a 
-vector for use by the program.
-
-    > example.exe --include-path=a/b/c --include-path d/e/f -I g/h/i -Ij/k/l
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: INFO
-    Include Path:
-       a/b/c
-       d/e/f
-       g/h/i
-       j/k/l
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-There are also the option of flags that do not take parameters and just set a 
-boolean value to true. In this case, running the gui also causes default values
-for the gui to be output to the screen.
-
-    > example.exe --run-gui
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: INFO
-    Include Path:
-    Master-File:
-    Additional Files:
-    GUI Enabled: true
-    GUI Height: 100
-    GUI Width: 100
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-There are also "positional" options at the end of the command line. The first
-one specifies the "master" file the others are additional files.
-
-    > example.exe --path=a-path -I an-include master.cpp additional1.cpp additional2.cpp
-    First 75 chars of the system path:
-    a-path
-    Verbosity: INFO
-    Include Path:
-       an-include
-    Master-File: master.cpp
-    Additional Files:
-       additional1.cpp
-       additional2.cpp
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-Environment Variables
----------------------
-In addition to the PATH environment variable, it also knows how to read the 
-EXAMPLE_VERBOSE environmental variable and use that to set the verbosity
-option/
-
-    > set EXAMPLE_VERBOSE=DEBUG
-    > example.exe
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: DEBUG
-    Include Path:
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-However, if the --verboseity flag is also set, it will override the env
-variable. This illustrates an important example, the way program_options works,
-is that a parser will not override a value that has previously been set by 
-another parser. Thus the env parser doesn't override the command line parser.
-(We will see this again in config files.) Default values are seperate from this
-heirarcy, they only apply if no parser has set the value and it is being read.
-
-    > set EXAMPLE_VERBOSE=DEBUG
-    > example.exe --verbosity=WARN
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: WARN
-    Include Path:
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-(You can unset an environmental variable with an empty set command)
-   
-    > set EXAMPLE_VERBOSE=
-    > example.exe
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: INFO
-    Include Path:
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-
-Config Files
-------------
-Config files generally follow the [INI file format]
-(https://en.wikipedia.org/wiki/INI_file) with a few exceptions. 
-
-Values can be simply added tp options with an equal sign. Here are two include
-paths added via the default config file (default.cfg), you can have optional
-spaces around the equal sign.
-
-    # You can use comments in a config file
-    include-path=first/default/path
-    include-path = second/default/path
-
-Results in
-
-    > example.exe
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: INFO
-    Include Path:
-       first/default/path
-       second/default/path
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 127.0.0.1
-    Network Port: 12345
-
-Values can also be in sections of the config file. Again, editing default.cfg
-
-    include-path=first/default/path
-    include-path = second/default/path
-
-    [network]
-    ip=1.2.3.4
-    port=3000
-
-Results in
-
-    > example.exe
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: INFO
-    Include Path:
-       first/default/path
-       second/default/path
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 1.2.3.4
-    Network Port: 3000
-
-This example is also setup to allow multiple config files to be specified on
-the command line, which are checked before the default.cfg file is read (but
-after the environment and command line parsing). Thus we can set the first.cfg
-file to contain the following:
-
-    verbosity=ERROR
-
-    [network]
-    ip = 5.6.7.8
-
-Results in:
-
-    > example.exe --config first.cfg
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: ERROR
-    Include Path:
-       first/default/path
-       second/default/path
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 5.6.7.8
-    Network Port: 3000
-
-But since the config files are read after the command line, setting the
-verbosity there causes the value in the file to be ignored.
-
-    > example.exe --config first.cfg --verbosity=WARN
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: WARN
-    Include Path:
-       first/default/path
-       second/default/path
-    Master-File:
-    Additional Files:
-    GUI Enabled: false
-    Network Address: 5.6.7.8
-    Network Port: 3000
-
-The config files are parsed in the order they are received on the command line.
-So adding the second.cfg file:
-
-    verbosity=FATAL
-    run-gui=true
-
-    [gui]
-    height=720
-    width=1280
-
-Results in a combination of all three config files:
-
-    > example.exe --config first.cfg --config second.cfg
-    First 75 chars of the system path:
-    C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
-    Verbosity: ERROR
-    Include Path:
-       first/default/path
-       second/default/path
-    Master-File:
-    Additional Files:
-    GUI Enabled: true
-    GUI Height: 720
-    GUI Width: 1280
-    Network Address: 5.6.7.8
-    Network Port: 3000
-
-Incidently the boolean run-gui option could have been set a number of ways 
-that all result in the C++ boolean value of true:
-
-    run-gui=true
-    run-gui=on
-    run-gui=1
-    run-gui=yes
-    run-gui=
-
-Since run-gui is an option that was set with the bool_switch type, which
-forces its use on the command line without a parameter (i.e. --run-gui instead
-of --run-gui=true) it can't be given a "false" option, bool_switch values can 
-only be turned true. If instead we had a value ("my-switch", po::value<bool>())
-that could be set at the command line --my-switch=true or --my-switch=false, or 
-any of the other types of boolean keywords true: true, on, 1, yes; 
-false: false, off, 0, no. In a config file this could look like:
-
-    my-switch=true
-    my-switch=on
-    my-switch=1
-    my-switch=yes
-    my-switch=
-
-    my-switch=false
-    my-switch=off
-    my-switch=0
-    my-switch=no
