Subject: [PATCH] New convenience rule package.install. Use that rule in
 top-level Jamfile.v2. Introduce new top-level Jamfile rule 'boost-install'.
 Use it in date_time, other libraries to follow soon.

+#  Provides mechanism for installing whole packages into a specific
+#  directory structure. This is opposed to the 'install' rule, that
+#  installs a number of targets to a single directory, and does not
+#  care about directory structure at all.
+
+#  Example usage:
+#
+#    package.install boost : <properties>
+#                          : <binaries>
+#                          : <libraries>
+#                          : <headers>
+#                          ;
+#
+#  This will install binaries, libraries and headers to the 'proper' location, given
+#  by command line options --prefix, --exec-prefix, --bindir, --libdir and 
+#  --includedir. 
+#
+#  The rule is just a convenient wrapper, avoiding the need to define several
+#  'install' targets.
+#
+#  The only install-related feature is <install-source-root>. It will apply to
+#  headers only and if present, paths of headers relatively to source root will be
+#  retained after installing. If it's not specified, then "." is assumed, so 
+#  relative paths in headers are always preserved.
