Don't worry about help2man as its use will be optional. As for
getopt_long I would like to use it as I'd rather not implement my own
cross platform option parsing. I would like to see the following
strategy forward: There is the GNU Portability Library
(http://www.gnu.org/software/gnulib/) which is basically a collection of
code snippets that tie in with automake. So in the case of getopt there
are automake macros which test the capabilities of getopt.h and in the
case of a non-gnu or non-posix provide their own implementation of
getopt_long. This should have us covered for any Unix, Windows and Mac
and probably more. I got the idea when looking at the source code of GNU
hello :-).
I will try to set up the whole thing on a separate branch where it can
be tested and evaluated. If we decide that we like it we can merge it
back to the main branch.
Comments, ideas, objections?
Thanks
Christian
