# DocMaker is a very simple program used to generate HTML documentation
# from the source files of the FreeType packages.
# DocMaker 0.1 (c) 2000-2001 David Turner <david@freetype.org>
#
# DocMaker is a very simple program used to generate the API Reference
# of programs by extracting comments from source files, and generating
# the equivalent HTML documentation.
#
# DocMaker is very similar to other tools like Doxygen, with the
# following differences:
#
# - it is written in Python (so it's slow, but easy to maintain and
# improve)
#
# - the comment syntax used by DocMaker is simpler and makes for
# clearer comments
#
# Of course, it doesn't have all the goodies of most similar tools,
# (e.g. C++ class hierarchies), but hey, it's only 2000 lines of
# python
#
# DocMaker is mainly used to generate the API references of several
# FreeType packages.
#
# I should really be using regular expressions to do this, but hey,
# i'm too lazy right now, and the damn thing seems to work :-)
