+The GNU C++ library sources have been specially formatted so that with the
+proper invocation of another tool (Doxygen), a set of HTML pages
+are generated from the sources files themselves. The resultant
+documentation is referred to as Source Level Documentation, and is
+useful for examining the signatures of public member functions for
+the library classes, finding out what is in a particular include
+file, looking at inheritance diagrams, etc.

+The source-level documentation for the most recent releases can be
+viewed online:

+This generated HTML collection, as above, is also available for download in the libstdc++ snapshots directory at
+ <literal><URL:ftp://gcc.gnu.org/pub/gcc/libstdc++/doxygen/></literal>.
+ You will almost certainly need to use one of the
+ <ulink url="http://gcc.gnu.org/mirrors.html">mirror sites</ulink> to download
+ the tarball. After unpacking, simply load libstdc++-html-*/index.html
+ into a browser.

+Documentation for older releases is available for download only, not
+online viewing.

+In addition, an initial set of man pages are also available in the
+same place as the HTML collections. Start with C++Intro(3).
