Mark> I'm not sure what argp is (pointer, Tom?)

argp is an options-parsing library by Miles Bader.  He wrote it for
HURD.

I didn't see it on alpha, sigh.  There are some examples of how to use
it there, but that's hardly helpful.

argp has the nice feature of automatically generating (nice-looking!)
`--help' output.  It also is implemented as a layer over GNU getopt.
This is a feature because it means that it will handle the
POSIXLY_CORRECT stuff properly.

However, if it isn't being actively developed, then maybe we should
avoid it.  I'll ask around.

Mark> Take a look at http://nis-www.lanl.gov/~jt/Software/

I looked at this.  It seems roughly equivalent to the argp package.
The argp package might generate slightly nicer --help output, and I
don't think opt handles the POSIX stuff.  These things probably don't
matter as much as the maintainership issue.


I'll send "arg.h" (which describes argp fairly well) to anybody who is
interested.
