The GNU C++ library sources have been specially formatted so that
with the proper invocation of another tool (Doxygen), a set of
indexed reference material can generated from the sources files
themselves. The resultant documentation is referred to as the API
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.
