Michael C. Martin e47073bc1d New command-line system. 
This is a full optparse-based parser for all the options we want
to have in Ophis 2.0, but the pass-disablers aren't working yet.

This also doesn't handle positional arguments the way we hope
to eventually; that will come later.

optparse is deprecated in 2.7, but its replacement isn't available
in any previous version of Python, so we avoid it so as to not
gratuitously break compatibility on older machines.

It would be nice to at least stay usable on stock Leopard Macs (2.5).

README 

Ophis is a cross-assembler for the 65xx series of chips. It supports
the stock 6502 opcodes, the 65c02 extensions, and syntax for the
"undocumented opcodes" in the 6510 chip used on the Commodore
64. (Syntax for these opcodes matches those given in the VICE team's
documentation.)

Ophis is written in pure Python and should be highly portable.
