+17 August 2003
+Added support for insertion of user code in the generated code.
+
+16 August 2003
+Applied a patch by Gottfried Ganssauge that adds exception specifiers to 
+wrapper functions and pointer declarations. Thanks a lot Gottfried!!
+
+Applied a patch by Prabhu Ramachandran that fixes ae problem with the 
+pure virtual method generation. Thanks again Prabhu!
+
+10 August 2003
+Support for incremental generation of the code has been added. This changes
+how --multiple works; documentation of this new feature will follow. Thanks
+to Prabhu Ramachandran, that saw the need for this feature and discussed a
+solution. 
+
+Automatically convert \ to / in Windows systems before passing the paths to
+gccxml.
+
+Fixed a bug reported by Prabhu Ramachandran, where in some classes the virtual
+methods were being definied incorrectly. Thanks a lot Prabhu!
+
+7 July 2003
+Applied 2 patches by Prabhu Ramachandran: a fix in the new --multiple method,
+and two new functions "hold_with_shared_ptr" and its counterpart for auto_ptr.
+Thanks a lot Prabhu!
+
+Fixed a bug where the macro BOOST_PYTHON_OPAQUE_SPECIALIZED_TYPE_ID was being
+called multiple times for the same type.
+Thanks to Gottfried Ganßauge for reporting this!
+
+Fixed bug where using AllFromHeader didn't use bases<> when exporting 
+hierarchies.
+
+Fixed the staticmethod bug.
+
+5 July 2003
+Changed how --multiple works: now it generates one cpp file for each pyste
+file, makeing easier to integrate Pyste with build systems.
+
+4 July 2003
+Applied patch that solved a bug in ClassExporter and added a distutils install
+script (install/setup.py), both contributed by Prabhu Ramachandran.
+Thanks Prabhu!
+
+2 July 2003
+Jim Wilson found a bug where types like "char**" were being interpreted as 
+"char*". Thanks Jim!
+
+16 June 2003
+Thanks to discussions with David Abrahams and Roman Sulzhyk, some behaviours
+have changed:
+
+- If you export a derived class without exporting its base classes, the derived
+  class will explicitly export the bases's methods and attributes. Before, if
+  you were interested in the bases's methods, you had to export the base
+  classes too.
+
+- Added a new function, no_override. When a member function is specified as
+  "no_override", no virtual wrappers are generated for it, improving
+  performance and letting the code more clean.
+
+- There was a bug in which the policy of virtual member functions was being
+  ignored (patch by Roman Sulzhyk). 
+  
+Thanks again to Roman Sulzhyk for the patches and discussion in the c++-sig.
+
+4 June 2003
+Major improvements in memory usage.
+
+3 June 2003
+Appliced a patch from Giulio Eulisse that allows unnamed enumerations to be
+exported with an AllFromHeader construct. Thanks a lot Giulio!
+
+2 June 2003
+Added a new construct, add_method. See documentation.
+
+23 May 2003
+Support for global variables added.
+Various bug fixes.
+
+08 May 2003
+Fixed bug where in a certain cases the GCCXMLParser would end up with multiple
+declarations of the same class
+
+22 Apr 2003
+- Now shows a warning when the user tries to export a forward-declared class.
+  Forward-declared classes are ignored by the AllFromHeader construct.
+- Fixed a bug where classes, functions and enums where being exported, even if
+  excluded from a AllFromHeader construct.
+
+16 Apr 2003
+Added a more generic (but ugly) code to declare the smart pointer converters.
+
+07 Apr 2003
+- Removed the warnings about forward declarations: it was not accurate enough.
+  Another strategy must be thought of.
+- Fixed bug in the --multiple mode, where the order of the class instantiations
+  could end up wrong.
+- Lots of fixes in the documentation, pointed out by Dirk Gerrits. Thanks Dirk!
+- Fixed support for the return_opaque_pointer policy (the support macro was not
+  being declared).
+
+
+06 Apr 2003
+Support for the improved static data members support of Boost.Python.
+
+05 Apr 2003
+New option for generating the bindings: --multiple.
+
+02 Apr 2003
+Forward declarations are now detected and a warning is generated.
+
+24 Mar 2003
+Default policy for functions/methods that return const T& is now
+return_value_policy<copy_const_reference>().
+
+22 Mar 2003
+Exporting virtual methods of the base classes in the derived classes too.
+
+21 Mar 2003
+Added manual support for boost::shared_ptr and std::auto_ptr (see doc).
+
+19 Mar 2003 
+Added support for int, double, float and long operators acting as expected in
+python.
+
+14 Mar 2003 
+Fixed bug: Wrappers for protected and virtual methods were not being generated.

+Pyste - Python Semi-Automatic Exporter
+======================================
+
+Pyste is a Boost.Python code generator. The user specifies the classes and
+functions to be exported using a simple interface file, which following the
+Boost.Python's philosophy, is simple Python code. Pyste then uses GCCXML to
+parse all the headers and extract the necessary information to automatically
+generate C++ code.
+
+The documentation can be found in the file index.html accompaning this README.
+
+Enjoy!
+Bruno da Silva de Oliveira (nicodemus@globalite.com.br)

+- David Abrahams, creator of Boost.Python, for tips on the syntax of the interface
+  file and support.
+- Marcelo Camelo, for design tips, support and inspiration for this project.

+====
+
+Pyste is a young tool, so please help it to get better! Send bug reports to
+nicodemus@globalite.com.br, accompaining the stack trace in case of exceptions.
+If possible, run pyste with --debug, and send the resulting xmls too (pyste
+will output a xml file with the same of each header it parsed).

+Suppose that you want to add a function to a class, turning it into a member
+function:</p>
+<code><pre>
+    <span class=keyword>struct </span><span class=identifier>World
+    </span><span class=special>{
+        </span><span class=keyword>void </span><span class=identifier>set</span><span class=special>(</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>msg</span><span class=special>) { </span><span class=keyword>this</span><span class=special>-&gt;</span><span class=identifier>msg </span><span class=special>= </span><span class=identifier>msg</span><span class=special>; }
+        </span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>msg</span><span class=special>;
+    };
+

+        </span><span class=keyword>return </span><span class=identifier>w</span><span class=special>.</span><span class=identifier>msg</span><span class=special>;
+    }
+</span></pre></code>
+<p>
+Here, we want to make <tt>greet</tt> work as a member function of the class <tt>World</tt>. We do
+that using the <tt>add_method</tt> construct:</p>
+<code><pre>
+    <span class=identifier>W </span><span class=special>= </span><span class=identifier>Class</span><span class=special>(</span><span class=string>&quot;World&quot;</span><span class=special>, </span><span class=string>&quot;hello.h&quot;</span><span class=special>)
+    </span><span class=identifier>add_method</span><span class=special>(</span><span class=identifier>W</span><span class=special>, </span><span class=string>&quot;greet&quot;</span><span class=special>)
+</span></pre></code>
+<p>
+Notice also that then you can rename it, set its policy, just like a regular
+member function:</p>
+<code><pre>
+    <span class=identifier>rename</span><span class=special>(</span><span class=identifier>W</span><span class=special>.</span><span class=identifier>greet</span><span class=special>, </span><span class=literal>'Greet'</span><span class=special>)

+<p>
+Now from Python:</p>
+<code><pre>
+    <span class=special>&gt;&gt;&gt; </span><span class=identifier>import </span><span class=identifier>hello
+    </span><span class=special>&gt;&gt;&gt; </span><span class=identifier>w </span><span class=special>= </span><span class=identifier>hello</span><span class=special>.</span><span class=identifier>World</span><span class=special>()

+    </span><span class=special>{

+</span></pre></code>
+<p>
+You can just use the <tt>AllFromHeader</tt> construct:</p>
+<code><pre>
+    <span class=identifier>hello </span><span class=special>= </span><span class=identifier>AllFromHeader</span><span class=special>(</span><span class=string>&quot;hello.h&quot;</span><span class=special>)
+</span></pre></code>
+<p>
+this will export all the declarations found in <tt>hello.h</tt>, which is equivalent
+to write:</p>
+<code><pre>
+    <span class=identifier>Class</span><span class=special>(</span><span class=string>&quot;World&quot;</span><span class=special>, </span><span class=string>&quot;hello.h&quot;</span><span class=special>)

+</span></pre></code>
+<p>
+Note that you can still use the functions <tt>rename</tt>, <tt>set_policy</tt>, <tt>exclude</tt>, etc. Just access

+<code><pre>

+<code><pre>
+    <span class=keyword>struct </span><span class=identifier>World

+<p>
+Here's the interface file for it, named <tt>world.pyste</tt>:</p>
+<code><pre>

+</span></pre></code>
+<p>
+and that's it!</p>
+<p>
+The next step is invoke Pyste in the command-line:</p>
+<code><pre>python pyste.py --module=hello world.pyste</pre></code><p>
+this will create a file &quot;<tt>hello.cpp</tt>&quot; in the directory where the command was

+[def GCCXML             [@http://www.gccxml.org GCCXML]]
+[def Boost.Python       [@../../index.html Boost.Python]]
+
+[page Introduction]
+
+[h2 What is Pyste?]
+
+Pyste is a Boost.Python code generator. The user specifies the classes and
+functions to be exported using a simple ['interface file], which following the
+Boost.Python's philosophy, is simple Python code. Pyste then uses GCCXML to
+parse all the headers and extract the necessary information to automatically
+generate C++ code.
+
+[h2 Example]
+
+Let's borrow the class [^World] from the [@../../doc/tutorial/doc/exposing_classes.html tutorial]: 
+
+    struct World
+    {
+        void set(std::string msg) { this->msg = msg; }
+        std::string greet() { return msg; }
+        std::string msg;
+    };
+
+Here's the interface file for it, named [^world.pyste]:
+
+    Class("World", "world.h")
+
+and that's it!
+
+The next step is invoke Pyste in the command-line:
+
+[pre python pyste.py --module=hello world.pyste]
+
+this will create a file "[^hello.cpp]" in the directory where the command was
+run. 
+
+Pyste supports the following features:
+
+* Functions
+* Classes
+* Class Templates
+* Virtual Methods
+* Overloading
+* Attributes 
+* Enums (both "free" enums and class enums)
+* Nested Classes
+* Support for [^boost::shared_ptr] and [^std::auto_ptr]
+* Global Variables
+
+[page Running Pyste]
+
+To run Pyste, you will need:
+
+* Python 2.2, available at [@http://www.python.org python's website].
+* The great [@http://effbot.org elementtree] library, from Fredrik Lundh.
+* The excellent GCCXML, from Brad King.
+
+Installation for the tools is available in their respective webpages.
+
+[blurb 
+[$theme/note.gif] GCCXML must be accessible in the PATH environment variable, so
+that Pyste can call it. How to do this varies from platform to platform.
+]
+
+[h2 Ok, now what?]
+
+Well, now let's fire it up:
+
+[pre 
+'''
+>python pyste.py
+
+Pyste version 0.6.5
+
+Usage:
+    pyste [options] --module=<name> interface-files
+
+where options are:
+    -I <path>           add an include path    
+    -D <symbol>         define symbol    
+    --multiple          create various cpps (one for each pyste file), instead
+                        of only one (useful during development)                        
+    --out               specify output filename (default: <module>.cpp)
+                        in --multiple mode, this will be a directory
+    --no-using          do not declare "using namespace boost";
+                        use explicit declarations instead
+    --pyste-ns=<name>   set the namespace where new types will be declared;
+                        default is the empty namespace
+    --debug             writes the xml for each file parsed in the current
+                        directory
+    -h, --help          print this help and exit
+    -v, --version       print version information      
+'''                        
+]
+
+Options explained:
+
+The [^-I] and [^-D] are preprocessor flags, which are needed by GCCXML to parse
+the header files correctly and by Pyste to find the header files declared in the
+interface files.
+
+[^--multiple] tells Pyste to generate multiple cpps for this module (one for
+each header parsed) in the directory named by [^--out], instead of the usual
+single cpp file. This mode is useful during development of a binding, because
+you are constantly changing source files, re-generating the bindings and
+recompiling. This saves a lot of time in compiling.
+
+[^--out] names the output file (default: [^<module>.cpp]), or in multiple mode,
+names a output directory for the files (default: [^<module>]).
+
+[^--no-using] tells Pyste to don't declare "[^using namespace boost;]" in the
+generated cpp, using the namespace boost::python explicitly in all declarations.
+Use only if you're having a name conflict in one of the files.
+
+Use [^--pyste-ns] to change the namespace where new types are declared (for
+instance, the virtual wrappers). Use only if you are having any problems. By
+default, Pyste uses the empty namespace.
+
+[^--debug] will write in the current directory a xml file as outputted by GCCXML
+for each header parsed. Useful for bug reports.
+
+[^-h, --help, -v, --version] are self-explaining, I believe. ;)
+
+So, the usage is simple enough:
+
+[pre >python pyste.py --module=mymodule file.pyste file2.pyste ...]
+
+will generate a file [^mymodule.cpp] in the same dir where the command was
+executed. Now you can compile the file using the same instructions of the
+[@../../doc/tutorial/doc/building_hello_world.html tutorial]. Or, if you prefer:
+
+[pre >python pyste.py --module=mymodule --multiple file.pyste file2.pyste ...]
+
+will create a directory named "mymodule" in the current directory, and will
+generate a bunch of cpp files, one for each header exported. You can then
+compile them all into a single shared library (or dll).
+
+[h2 Wait... how do I set those I and D flags?]
+
+Don't worry: normally GCCXML is already configured correctly for your plataform, 
+so the search path to the standard libraries and the standard defines should 
+already be set. You only have to set the paths to other libraries that your code 
+needs, like Boost, for example.
+
+Plus, Pyste automatically uses the contents of the environment variable
+[^INCLUDE] if it exists. Visual C++ users should run the [^Vcvars32.bat] file,
+which for Visual C++ 6 is normally located at:
+
+    C:\Program Files\Microsoft Visual Studio\VC98\bin\Vcvars32.bat
+
+with that, you should have little trouble setting up the flags.
+
+[blurb [$theme/note.gif][*A note about Psyco][br][br]
+Although you don't have to install [@http://psyco.sourceforge.net/ Psyco] to use Pyste, if you do, Pyste will make use of it to speed up the wrapper generation. Speed ups of 30% can be achieved, so it's highly recommended.
+]
+
+[page The Interface Files]
+
+The interface files are the heart of Pyste. The user creates one or more
+interface files declaring the classes and functions he wants to export, and then
+invokes Pyste passing the interface files to it. Pyste then generates a single
+cpp file with Boost.Python code, with all the classes and functions exported.
+
+Besides declaring the classes and functions, the user has a number of other
+options, like renaming e excluding classes and member functionis. Those are
+explained later on.
+
+[h2 Basics]
+
+Suppose we have a class and some functions that we want to expose to Python
+declared in the header [^hello.h]:
+
+    struct World
+    {
+        World(std::string msg): msg(msg) {} 
+        void set(std::string msg) { this->msg = msg; }
+        std::string greet() { return msg; }
+        std::string msg;
+    };
+
+    enum choice { red, blue };
+    
+    namespace test {
+    
+    void show(choice c) { std::cout << "value: " << (int)c << std::endl; }
+    
+    }
+
+We create a file named [^hello.pyste] and create instances of the classes
+[^Function], [^Class] and [^Enum]:
+
+    Function("test::show", "hello.h")
+    Class("World", "hello.h")
+    Enum("choice", "hello.h")
+
+That will expose the class, the free function and the enum found in [^hello.h]. 
+
+[page:1 Renaming and Excluding]
+
+You can easily rename functions, classes, member functions, attributes, etc. Just use the
+function [^rename], like this:
+
+    World = Class("World", "hello.h")
+    rename(World, "IWorld")
+    show = Function("choice", "hello.h")
+    rename(show, "Show")
+
+You can rename member functions and attributes using this syntax:
+
+    rename(World.greet, "Greet")
+    rename(World.set, "Set")
+    choice = Enum("choice", "hello.h")
+    rename(choice.red, "Red")
+    rename(choice.blue, "Blue")
+
+You can exclude functions, classes, member functions, attributes, etc, in the same way,
+with the function [^exclude]:
+
+    exclude(World.greet)
+    exclude(World.msg)
+
+To access the operators of a class, access the member [^operator] like this
+(supposing that [^C] is a class being exported):
+
+    exclude(C.operator['+'])
+    exclude(C.operator['*'])
+    exclude(C.operator['<<'])
+
+The string inside the brackets is the same as the name of the operator in C++.[br]
+
+[h2 Virtual Member Functions]
+
+Pyste automatically generates wrappers for virtual member functions, but you
+may want to disable this behaviour (for performance reasons, or to let the
+code more clean) if you do not plan to override the functions in Python. To do
+this, use the function [^final]:
+
+    C = Class('C', 'C.h')
+    final(C.foo) # C::foo is a virtual member function
+
+No virtual wrapper code will be generated for the virtual member function
+C::foo that way.
+
+[page:1 Policies]
+
+Even thought Pyste can identify various elements in the C++ code, like virtual
+member functions, attributes, and so on, one thing that it can't do is to
+guess the semantics of functions that return pointers or references. In this
+case, the user must manually specify the policy. Policies are explained in the
+[@../../doc/tutorial/doc/call_policies.html tutorial].
+
+The policies in Pyste are named exactly as in Boost.Python, only the syntax is
+slightly different. For instance, this policy:
+
+    return_internal_reference<1, with_custodian_and_ward<1, 2> >()
+
+becomes in Pyste:    
+
+    return_internal_reference(1, with_custodian_and_ward(1, 2))
+
+The user can specify policies for functions and virtual member functions with
+the [^set_policy] function:
+
+    set_policy(f, return_internal_reference())
+    set_policy(C.foo, return_value_policy(manage_new_object))
+
+[blurb 
+[$theme/note.gif] [*What if a function or member function needs a policy and
+the user doesn't set one?][br][br] If a function needs a policy and one
+was not set, Pyste will issue a error.  The user should then go in the
+interface file and set the policy for it, otherwise the generated cpp won't
+compile.
+]
+
+[blurb
+[$theme/note.gif] 
+Note that, for functions that return [^const T&], the policy
+[^return_value_policy<copy_const_reference>()] wil be used by default, because
+that's normally what you want. You can change it to something else if you need
+to, though.
+]
+
+[page:1 Templates]
+
+Template classes can easily be exported too, but you can't export the template
+itself... you have to export instantiations of it! So, if you want to export a
+[^std::vector], you will have to export vectors of int, doubles, etc.
+
+Suppose we have this code:
+
+    template <class T>
+    struct Point
+    {
+        T x;
+        T y;
+    };
+
+And we want to export [^Point]s of int and double:
+
+    Point = Template("Point", "point.h")
+    Point("int")
+    Point("double")
+
+Pyste will assign default names for each instantiation. In this example, those
+would be "[^Point_int]" and "[^Point_double]", but most of the time users will want to
+rename the instantiations:
+
+    Point("int", "IPoint")         // renames the instantiation
+    double_inst = Point("double")  // another way to do the same
+    rename(double_inst, "DPoint")
+
+Note that you can rename, exclude, set policies, etc, in the [^Template] object
+like you would do with a [^Function] or a [^Class]. This changes affect all
+[*future] instantiations:
+
+    Point = Template("Point", "point.h")
+    Point("float", "FPoint")        // will have x and y as data members
+    rename(Point.x, "X")
+    rename(Point.y, "Y")
+    Point("int", "IPoint")          // will have X and Y as data members
+    Point("double", "DPoint")       // also will have X and Y as data member
+
+If you want to change a option of a particular instantiation, you can do so:
+
+    Point = Template("Point", "point.h")
+    Point("int", "IPoint")          
+    d_inst = Point("double", "DPoint")       
+    rename(d_inst.x, "X")           // only DPoint is affect by this renames,
+    rename(d_inst.y, "Y")           // IPoint stays intact
+
+[blurb [$theme/note.gif] [*What if my template accepts more than one type?]
+[br][br]
+When you want to instantiate a template with more than one type, you can pass
+either a string with the types separated by whitespace, or a list of strings
+'''("int double" or ["int", "double"]''' would both work).
+]
+
+[page:1 Wrappers]
+
+Suppose you have this function:
+
+    std::vector<std::string> names();
+
+But you don't want to export [^std::vector<std::string>], you want this function
+to return a python list of strings. Boost.Python has excellent support for
+that:
+
+    list names_wrapper()
+    {
+        list result;
+        // call original function
+        vector<string> v = names();
+        // put all the strings inside the python list
+        vector<string>::iterator it;
+        for (it = v.begin(); it != v.end(); ++it){
+            result.append(*it);    
+        }
+        return result;
+    }
+    
+    BOOST_PYTHON_MODULE(test)
+    {
+        def("names", &names_wrapper);
+    }
+
+Nice heh? Pyste supports this mechanism too. You declare the [^names_wrapper]
+function in a header named "[^test_wrappers.h]" and in the interface file:
+
+    Include("test_wrappers.h")
+    names = Function("names", "test.h")
+    set_wrapper(names, "names_wrapper")
+
+You can optionally declare the function in the interface file itself:
+
+    names_wrapper = Wrapper("names_wrapper",
+    """
+    list names_wrapper()
+    {
+        // code to call name() and convert the vector to a list...
+    }
+    """)
+    names = Function("names", "test.h")
+    set_wrapper(names, names_wrapper)
+
+The same mechanism can be used with member functions too. Just remember that
+the first parameter of wrappers for member functions is a pointer to the
+class, as in:
+
+    struct C
+    {
+        std::vector<std::string> names();
+    }
+
+    list names_wrapper(C* c)
+    {
+        // same as before, calling c->names() and converting result to a list 
+    }
+
+And then in the interface file:
+
+    C = Class("C", "test.h")
+    set_wrapper(C.names, "names_wrapper")
+
+[blurb 
+[$theme/note.gif]Even though Boost.Python accepts either a pointer or a
+reference to the class in wrappers for member functions as the first parameter,
+Pyste expects them to be a [*pointer]. Doing otherwise will prevent your
+code to compile when you set a wrapper for a virtual member function.
+]
+
+[page:1 Exporting An Entire Header]
+
+Pyste also supports a mechanism to export all declarations found in a header
+file. Suppose again our file, [^hello.h]:
+
+    struct World
+    {
+        World(std::string msg): msg(msg) {} 
+        void set(std::string msg) { this->msg = msg; }
+        std::string greet() { return msg; }
+        std::string msg;
+    };
+
+    enum choice { red, blue };
+    
+    void show(choice c) { std::cout << "value: " << (int)c << std::endl; } 
+
+You can just use the [^AllFromHeader] construct:
+
+    hello = AllFromHeader("hello.h")
+
+this will export all the declarations found in [^hello.h], which is equivalent
+to write:
+
+    Class("World", "hello.h")
+    Enum("choice", "hello.h")
+    Function("show", "hello.h")
+
+Note that you can still use the functions [^rename], [^set_policy], [^exclude], etc. Just access
+the members of the header object like this:
+
+    rename(hello.World.greet, "Greet")
+    exclude(hello.World.set, "Set")
+
+
+[page:1 Smart Pointers]
+
+Pyste for now has manual support for smart pointers. Suppose:
+
+    struct C
+    {
+        int value;
+    };
+
+    boost::shared_ptr<C> newC(int value)
+    {
+        boost::shared_ptr<C> c( new C() );
+        c->value = value;
+        return c;
+    }
+
+    void printC(boost::shared_ptr<C> c)
+    {
+        std::cout << c->value << std::endl;
+    }
+
+To make [^newC] and [^printC] work correctly, you have to tell Pyste that a
+convertor for [^boost::shared_ptr<C>] is needed.
+
+    C = Class('C', 'C.h')
+    use_shared_ptr(C)
+    Function('newC', 'C.h')
+    Function('printC', 'C.h')
+
+For [^std::auto_ptr]'s, use the function [^use_auto_ptr].
+
+This system is temporary, and in the future the converters will automatically be
+exported if needed, without the need to tell Pyste about them explicitly.
+
+[h2 Holders]
+
+If only the converter for the smart pointers is not enough and you need to
+specify the smart pointer as the holder for a class, use the functions
+[^hold_with_shared_ptr] and [^hold_with_auto_ptr]:
+
+    C = Class('C', 'C.h')
+    hold_with_shared_ptr(C)
+    Function('newC', 'C.h')
+    Function('printC', 'C.h') 
+
+[page:1 Global Variables]
+
+To export global variables, use the [^Var] construct:
+
+    Var("myglobal", "foo.h")
+
+Beware of non-const global variables: changes in Python won't reflect in C++!
+If you really must change them in Python, you will have to write some accessor
+functions, and export those.
+
+[page:1 Adding New Methods]
+
+Suppose that you want to add a function to a class, turning it into a member
+function:
+
+    struct World
+    {
+        void set(std::string msg) { this->msg = msg; }
+        std::string msg;
+    };
+
+    std::string greet(World& w)
+    {
+        return w.msg;
+    }
+
+Here, we want to make [^greet] work as a member function of the class [^World]. We do
+that using the [^add_method] construct:
+
+    W = Class("World", "hello.h")
+    add_method(W, "greet")
+
+Notice also that then you can rename it, set its policy, just like a regular
+member function:
+
+    rename(W.greet, 'Greet')
+
+Now from Python:
+
+    >>> import hello
+    >>> w = hello.World()
+    >>> w.set('Ni')
+    >>> w.greet()
+    'Ni'
+    >>> print 'Oh no! The knights who say Ni!'
+    Oh no! The knights who say Ni!

+<p>
+You can easily rename functions, classes, member functions, attributes, etc. Just use the
+function <tt>rename</tt>, like this:</p>
+<code><pre>
+    <span class=identifier>World </span><span class=special>= </span><span class=identifier>Class</span><span class=special>(</span><span class=string>&quot;World&quot;</span><span class=special>, </span><span class=string>&quot;hello.h&quot;</span><span class=special>)

+    </span><span class=identifier>rename</span><span class=special>(</span><span class=identifier>show</span><span class=special>, </span><span class=string>&quot;Show&quot;</span><span class=special>)
+</span></pre></code>
+<p>
+You can rename member functions and attributes using this syntax:</p>
+<code><pre>
+    <span class=identifier>rename</span><span class=special>(</span><span class=identifier>World</span><span class=special>.</span><span class=identifier>greet</span><span class=special>, </span><span class=string>&quot;Greet&quot;</span><span class=special>)
+    </span><span class=identifier>rename</span><span class=special>(</span><span class=identifier>World</span><span class=special>.</span><span class=identifier>set</span><span class=special>, </span><span class=string>&quot;Set&quot;</span><span class=special>)
+    </span><span class=identifier>choice </span><span class=special>= </span><span class=identifier>Enum</span><span class=special>(</span><span class=string>&quot;choice&quot;</span><span class=special>, </span><span class=string>&quot;hello.h&quot;</span><span class=special>)
+    </span><span class=identifier>rename</span><span class=special>(</span><span class=identifier>choice</span><span class=special>.</span><span class=identifier>red</span><span class=special>, </span><span class=string>&quot;Red&quot;</span><span class=special>)
+    </span><span class=identifier>rename</span><span class=special>(</span><span class=identifier>choice</span><span class=special>.</span><span class=identifier>blue</span><span class=special>, </span><span class=string>&quot;Blue&quot;</span><span class=special>)
+</span></pre></code>
+<p>
+You can exclude functions, classes, member functions, attributes, etc, in the same way,
+with the function <tt>exclude</tt>:</p>
+<code><pre>
+    <span class=identifier>exclude</span><span class=special>(</span><span class=identifier>World</span><span class=special>.</span><span class=identifier>greet</span><span class=special>)
+    </span><span class=identifier>exclude</span><span class=special>(</span><span class=identifier>World</span><span class=special>.</span><span class=identifier>msg</span><span class=special>)
+</span></pre></code>
+<p>
+To access the operators of a class, access the member <tt>operator</tt> like this
+(supposing that <tt>C</tt> is a class being exported):</p>
+<code><pre>
+    <span class=identifier>exclude</span><span class=special>(</span><span class=identifier>C</span><span class=special>.</span><span class=keyword>operator</span><span class=special>[</span><span class=literal>'+'</span><span class=special>])
+    </span><span class=identifier>exclude</span><span class=special>(</span><span class=identifier>C</span><span class=special>.</span><span class=keyword>operator</span><span class=special>[</span><span class=literal>'*'</span><span class=special>])
+    </span><span class=identifier>exclude</span><span class=special>(</span><span class=identifier>C</span><span class=special>.</span><span class=keyword>operator</span><span class=special>[</span><span class=literal>'&lt;&lt;'</span><span class=special>])
+</span></pre></code>
+<p>
+The string inside the brackets is the same as the name of the operator in C++.<br></p>
+<a name="virtual_member_functions"></a><h2>Virtual Member Functions</h2><p>
+Pyste automatically generates wrappers for virtual member functions, but you
+may want to disable this behaviour (for performance reasons, or to let the
+code more clean) if you do not plan to override the functions in Python. To do
+this, use the function <tt>final</tt>:</p>
+<code><pre>
+    <span class=identifier>C </span><span class=special>= </span><span class=identifier>Class</span><span class=special>(</span><span class=literal>'C'</span><span class=special>, </span><span class=literal>'C.h'</span><span class=special>)
+    </span><span class=identifier>final</span><span class=special>(</span><span class=identifier>C</span><span class=special>.</span><span class=identifier>foo</span><span class=special>) </span>##<span class=identifier>C</span><span class=special>::</span><span class=identifier>foo </span><span class=identifier>is </span><span class=identifier>a </span><span class=keyword>virtual </span><span class=identifier>member </span><span class=identifier>function
+</span></pre></code>
+<p>
+No virtual wrapper code will be generated for the virtual member function
+C::foo that way.</p>

+    -D &lt;symbol&gt;         define symbol

+    --out               specify output filename (default: &lt;module&gt;.cpp)
+                        in --multiple mode, this will be a directory
+    --no-using          do not declare &quot;using namespace boost&quot;;
+                        use explicit declarations instead
+    --pyste-ns=&lt;name&gt;   set the namespace where new types will be declared;
+                        default is the empty namespace
+    --debug             writes the xml for each file parsed in the current
+                        directory
+    -h, --help          print this help and exit
+    -v, --version       print version information      
+                        
+</pre></code><p>
+Options explained:</p>
+<p>
+The <tt>-I</tt> and <tt>-D</tt> are preprocessor flags, which are needed by <a href="http://www.gccxml.org">
+GCCXML</a> to parse
+the header files correctly and by Pyste to find the header files declared in the
+interface files.</p>
+<p>
+<tt>--multiple</tt> tells Pyste to generate multiple cpps for this module (one for
+each header parsed) in the directory named by <tt>--out</tt>, instead of the usual
+single cpp file. This mode is useful during development of a binding, because
+you are constantly changing source files, re-generating the bindings and
+recompiling. This saves a lot of time in compiling.</p>
+<p>
+<tt>--out</tt> names the output file (default: <tt>&lt;module&gt;.cpp</tt>), or in multiple mode,
+names a output directory for the files (default: <tt>&lt;module&gt;</tt>).</p>
+<p>
+<tt>--no-using</tt> tells Pyste to don't declare &quot;<tt>using namespace boost;</tt>&quot; in the
+generated cpp, using the namespace boost::python explicitly in all declarations.
+Use only if you're having a name conflict in one of the files.</p>
+<p>
+Use <tt>--pyste-ns</tt> to change the namespace where new types are declared (for
+instance, the virtual wrappers). Use only if you are having any problems. By
+default, Pyste uses the empty namespace.</p>
+<p>
+<tt>--debug</tt> will write in the current directory a xml file as outputted by <a href="http://www.gccxml.org">
+GCCXML</a>
+for each header parsed. Useful for bug reports.</p>
+<p>
+<tt>-h, --help, -v, --version</tt> are self-explaining, I believe. ;)</p>
+<p>
+So, the usage is simple enough:</p>
+<code><pre>&gt;python pyste.py --module=mymodule file.pyste file2.pyste ...</pre></code><p>
+will generate a file <tt>mymodule.cpp</tt> in the same dir where the command was
+executed. Now you can compile the file using the same instructions of the
+<a href="../../doc/tutorial/doc/building_hello_world.html">
+tutorial</a>. Or, if you prefer:</p>
+<code><pre>&gt;python pyste.py --module=mymodule --multiple file.pyste file2.pyste ...</pre></code><p>
+will create a directory named &quot;mymodule&quot; in the current directory, and will
+generate a bunch of cpp files, one for each header exported. You can then
+compile them all into a single shared library (or dll).</p>
+<a name="wait____how_do_i_set_those_i_and_d_flags_"></a><h2>Wait... how do I set those I and D flags?</h2><p>
+Don't worry: normally <a href="http://www.gccxml.org">
+GCCXML</a> is already configured correctly for your plataform, 
+so the search path to the standard libraries and the standard defines should 
+already be set. You only have to set the paths to other libraries that your code 
+needs, like Boost, for example.</p>
+<p>
+Plus, Pyste automatically uses the contents of the environment variable
+<tt>INCLUDE</tt> if it exists. Visual C++ users should run the <tt>Vcvars32.bat</tt> file,
+which for Visual C++ 6 is normally located at:</p>
+<code><pre>
+    <span class=identifier>C</span><span class=special>:\</span><span class=identifier>Program </span><span class=identifier>Files</span><span class=special>\</span><span class=identifier>Microsoft </span><span class=identifier>Visual </span><span class=identifier>Studio</span><span class=special>\</span><span class=identifier>VC98</span><span class=special>\</span><span class=identifier>bin</span><span class=special>\</span><span class=identifier>Vcvars32</span><span class=special>.</span><span class=identifier>bat
+</span></pre></code>
+<p>
+with that, you should have little trouble setting up the flags.</p>

+<p>
+To make <tt>newC</tt> and <tt>printC</tt> work correctly, you have to tell Pyste that a
+convertor for <tt>boost::shared_ptr&lt;C&gt;</tt> is needed.</p>
+<code><pre>
+    <span class=identifier>C </span><span class=special>= </span><span class=identifier>Class</span><span class=special>(</span><span class=literal>'C'</span><span class=special>, </span><span class=literal>'C.h'</span><span class=special>)

+</span></pre></code>
+<p>
+For <tt>std::auto_ptr</tt>'s, use the function <tt>use_auto_ptr</tt>.</p>
+<p>
+This system is temporary, and in the future the converters will automatically be
+exported if needed, without the need to tell Pyste about them explicitly.</p>
+<a name="holders"></a><h2>Holders</h2><p>
+If only the converter for the smart pointers is not enough and you need to
+specify the smart pointer as the holder for a class, use the functions

+Template classes can easily be exported too, but you can't export the template
+itself... you have to export instantiations of it! So, if you want to export a
+<tt>std::vector</tt>, you will have to export vectors of int, doubles, etc.</p>
+<p>
+Suppose we have this code:</p>
+<code><pre>
+    <span class=keyword>template </span><span class=special>&lt;</span><span class=keyword>class </span><span class=identifier>T</span><span class=special>&gt;
+    </span><span class=keyword>struct </span><span class=identifier>Point
+    </span><span class=special>{
+        </span><span class=identifier>T </span><span class=identifier>x</span><span class=special>;
+        </span><span class=identifier>T </span><span class=identifier>y</span><span class=special>;
+    };
+</span></pre></code>
+<p>
+And we want to export <tt>Point</tt>s of int and double:</p>
+<code><pre>
+    <span class=identifier>Point </span><span class=special>= </span><span class=identifier>Template</span><span class=special>(</span><span class=string>&quot;Point&quot;</span><span class=special>, </span><span class=string>&quot;point.h&quot;</span><span class=special>)
+    </span><span class=identifier>Point</span><span class=special>(</span><span class=string>&quot;int&quot;</span><span class=special>)
+    </span><span class=identifier>Point</span><span class=special>(</span><span class=string>&quot;double&quot;</span><span class=special>)
+</span></pre></code>
+<p>
+Pyste will assign default names for each instantiation. In this example, those
+would be &quot;<tt>Point_int</tt>&quot; and &quot;<tt>Point_double</tt>&quot;, but most of the time users will want to
+rename the instantiations:</p>
+<code><pre>
+    <span class=identifier>Point</span><span class=special>(</span><span class=string>&quot;int&quot;</span><span class=special>, </span><span class=string>&quot;IPoint&quot;</span><span class=special>)         // </span><span class=identifier>renames </span><span class=identifier>the </span><span class=identifier>instantiation
+    </span><span class=identifier>double_inst </span><span class=special>= </span><span class=identifier>Point</span><span class=special>(</span><span class=string>&quot;double&quot;</span><span class=special>)  // </span><span class=identifier>another </span><span class=identifier>way </span><span class=identifier>to </span><span class=keyword>do </span><span class=identifier>the </span><span class=identifier>same
+    </span><span class=identifier>rename</span><span class=special>(</span><span class=identifier>double_inst</span><span class=special>, </span><span class=string>&quot;DPoint&quot;</span><span class=special>)
+</span></pre></code>
+<p>
+Note that you can rename, exclude, set policies, etc, in the <tt>Template</tt> object
+like you would do with a <tt>Function</tt> or a <tt>Class</tt>. This changes affect all
+<b>future</b> instantiations:</p>
+<code><pre>
+    <span class=identifier>Point </span><span class=special>= </span><span class=identifier>Template</span><span class=special>(</span><span class=string>&quot;Point&quot;</span><span class=special>, </span><span class=string>&quot;point.h&quot;</span><span class=special>)

+The interface files are the heart of Pyste. The user creates one or more
+interface files declaring the classes and functions he wants to export, and then
+invokes Pyste passing the interface files to it. Pyste then generates a single
+cpp file with <a href="../../index.html">
+Boost.Python</a> code, with all the classes and functions exported.</p>
+<p>
+Besides declaring the classes and functions, the user has a number of other
+options, like renaming e excluding classes and member functionis. Those are
+explained later on.</p>
+<a name="basics"></a><h2>Basics</h2><p>
+Suppose we have a class and some functions that we want to expose to Python
+declared in the header <tt>hello.h</tt>:</p>
+<code><pre>
+    <span class=keyword>struct </span><span class=identifier>World
+    </span><span class=special>{

+    
+    }
+</span></pre></code>
+<p>
+We create a file named <tt>hello.pyste</tt> and create instances of the classes
+<tt>Function</tt>, <tt>Class</tt> and <tt>Enum</tt>:</p>
+<code><pre>
+    <span class=identifier>Function</span><span class=special>(</span><span class=string>&quot;test::show&quot;</span><span class=special>, </span><span class=string>&quot;hello.h&quot;</span><span class=special>)
+    </span><span class=identifier>Class</span><span class=special>(</span><span class=string>&quot;World&quot;</span><span class=special>, </span><span class=string>&quot;hello.h&quot;</span><span class=special>)

+That will expose the class, the free function and the enum found in <tt>hello.h</tt>. </p>

+<p>
+Nice heh? Pyste supports this mechanism too. You declare the <tt>names_wrapper</tt>
+function in a header named &quot;<tt>test_wrappers.h</tt>&quot; and in the interface file:</p>
+<code><pre>
+    <span class=identifier>Include</span><span class=special>(</span><span class=string>&quot;test_wrappers.h&quot;</span><span class=special>)
+    </span><span class=identifier>names </span><span class=special>= </span><span class=identifier>Function</span><span class=special>(</span><span class=string>&quot;names&quot;</span><span class=special>, </span><span class=string>&quot;test.h&quot;</span><span class=special>)
+    </span><span class=identifier>set_wrapper</span><span class=special>(</span><span class=identifier>names</span><span class=special>, </span><span class=string>&quot;names_wrapper&quot;</span><span class=special>)
+</span></pre></code>
+<p>
+You can optionally declare the function in the interface file itself:</p>
+<code><pre>
+    <span class=identifier>names_wrapper </span><span class=special>= </span><span class=identifier>Wrapper</span><span class=special>(</span><span class=string>&quot;names_wrapper&quot;</span><span class=special>,
+    </span><span class=string>&quot;&quot;</span><span class=string>&quot;
+    list names_wrapper()
+    {
+        // code to call name() and convert the vector to a list...
+    }
+    &quot;</span><span class=string>&quot;&quot;</span><span class=special>)
+    </span><span class=identifier>names </span><span class=special>= </span><span class=identifier>Function</span><span class=special>(</span><span class=string>&quot;names&quot;</span><span class=special>, </span><span class=string>&quot;test.h&quot;</span><span class=special>)
+    </span><span class=identifier>set_wrapper</span><span class=special>(</span><span class=identifier>names</span><span class=special>, </span><span class=identifier>names_wrapper</span><span class=special>)
+</span></pre></code>
+<p>
+The same mechanism can be used with member functions too. Just remember that
+the first parameter of wrappers for member functions is a pointer to the
+class, as in:</p>
+<code><pre>
+    <span class=keyword>struct </span><span class=identifier>C
+    </span><span class=special>{
+        </span><span class=identifier>std</span><span class=special>::</span><span class=identifier>vector</span><span class=special>&lt;</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string</span><span class=special>&gt; </span><span class=identifier>names</span><span class=special>();
+    }
+
+    </span><span class=identifier>list </span><span class=identifier>names_wrapper</span><span class=special>(</span><span class=identifier>C</span><span class=special>* </span><span class=identifier>c</span><span class=special>)
+    {
+        // </span><span class=identifier>same </span><span class=identifier>as </span><span class=identifier>before</span><span class=special>, </span><span class=identifier>calling </span><span class=identifier>c</span><span class=special>-&gt;</span><span class=identifier>names</span><span class=special>() </span><span class=keyword>and </span><span class=identifier>converting </span><span class=identifier>result </span><span class=identifier>to </span><span class=identifier>a </span><span class=identifier>list 
+    </span><span class=special>}
+</span></pre></code>
+<p>
+And then in the interface file:</p>
+<code><pre>
+    <span class=identifier>C </span><span class=special>= </span><span class=identifier>Class</span><span class=special>(</span><span class=string>&quot;C&quot;</span><span class=special>, </span><span class=string>&quot;test.h&quot;</span><span class=special>)
+    </span><span class=identifier>set_wrapper</span><span class=special>(</span><span class=identifier>C</span><span class=special>.</span><span class=identifier>names</span><span class=special>, </span><span class=string>&quot;names_wrapper&quot;</span><span class=special>)
+</span></pre></code>
