RE: Mac python programming

Nod well you have two very interested programmers over here that will help
if we can colaberate.  If not just let us know when it's all ready snicker.

Played around with it a bit more--I'll send you a diff offlist.

It's kind of a dirty hack at this point; I have reg ex's filtering out
the raw tts commands obtained from stdin.  The official servers
(espeak, outloud, etc) are all written using tcl.  Tcl, after a little
reading, has a very nice feature where its commandloop will map
commands received through stdin directly to procedures defined in the
script.  In python, we have to do this parsing ourselves which sucks.
Also, multiple "q" (that's tts speak chunks) get sent at one time so I
still need to put in queueing on the server side...

But, yes, it "talks", but not really yet all that functional, though it's
close.
