Yep. It would be a matter of following the symlink.

Hmm - a "good guess" type parser should be pretty easy:
1. skip everything behind a '#' on a line.
2. search for "Section" and "Pointer" within a line (strstr).
3. get next protocol and device entries, eventually looking for EndSection,
but that should already be Paranoia.

That should read pretty much any sane XF86config file. If someone breaks
lines and such, it's his fault IMHO.

YES. Would also help for other stuff. It would especially help LibGII and
LibGGI to avoid having to reconfigure the confdir every time, if they can
get it from LibGG.

And we should add a simple "escape-expander" wrapper for reading configfiles.
It should automatically handle a few simple escapes in the file and stuff like
file-inclusion.

How about:

FILE *ggConfOpen(char *conffilename);
ggConfGets(char *s, int size, FILE *stream);
ggConfClose(*stream);

Don't know, if we'd need writing/seeking. IMHO not a good idea.

And the Gets (modeled after fgets, in case you wonder) should
automatically do some trivial globbings like eating up comments
and doing stuff like

.include %home%/.ggi/bla.conf
.include %confdir%/bla.extended.conf

Maybe we should use @ instead of % a la autoconf ... ?

CU, ANdy
