[feature request] Doxygen comments for parser files

Dear List,

for the documentation of my current project I use doxygen. So I have all
my files pretty commented but not the parser files (cmdline.c and
cmdline.h). One can define such an option as --doxygen-comments to
enable this feature. Some comments are already in the source code but
not in the doxygen syntax. What do you think about it?

Best regards,
Yegor Yefremov
