getopt with negative numbers?

[J. Clifford Dyer]

If you can access the argument list manually, you could scan it for a negative integer, and then insert a '--' argument before that, if needed, before passing it to getopt/optparse.  Then you wouldn't have to worry about it on the command line. 

Cheers,
Cliff
