Regarding getflags(), here's an example of how I've used it with sokoban (the
shell version)


main(argc, argv)
int *argc;
char *argv;
{
	BOOL	optrestore = optscore = 0;
	int 	optlevel = 1;
	...
	getflags(&argc,&argv,"r,s,n#",&optrestore,&optscore,&optlevel);
	...
}

What it does is scan for -r, -s, or -n <number> (there need not be a space 
between n and <number> for getflags to recognize n as the flag and <number>
as the argument.  It will fill the boolean variables with a 1 if they are
present and fill optlevel with the argument following -n.

Sometimes it is more advantageous to use a homebrew flag checker, by just
making a loop for argc and checking each argv, as is the case with a lf2cr
converter I wrote, which has a command line like :
	lf2cr <filename> [-o <outputfile>] [-l] [-s]
getflags() only works (for me, at least) when you have a flag you want.  It
won't find a simple filename after the program name, unless it has a -flag
for it.

If that is hard to follow, I can probably confuse everyone more if they need
more help, but feel free to ask!
