# c2man.pl v0.1 Copyright (C) 2000 Mike McCormack
#
# Genenerates Documents from C source code.
#
# Input is source code with specially formatted comments, output
# is man pages. The functionality is meant to be similar to c2man.
# The following is an example provided in the Wine documentation.
#
# TODO:
# Write code to generate HTML output with the -Th option.
# Need somebody who knows about TROFF to help touch up the man page generation.
# Parse spec files passed with -w option and generate pages for the functions
# in the spec files only.
# Modify Makefiles to pass multiple C files to speed up man page generation.
# Use nm on the shared libraries specified in the spec files to determine which
# source files should be parsed, and only parse them.(requires wine to be compiled)
