[SciPy-user] chaco:I found W, now what?

Hey Jim,

Chaco itself is in quite a state of flux with things breaking and
getting fixed on a daily or at least weekly basis.  Until it stabilizes
a little more, keeping the docs updated will be difficult.  Sorry about
that, and I ask for your patience. :)  Also, most advances are made in
wxPython first.  On the positive side, it is getting close to being a
full implementation -- well as full of implementation as we plan.

My experience with a the Mac and Python cover a total of maybe 2 days,
and the whole thing continues to befuddle me.  Line endings, framework
vs. non-framework builds, resource forks, creator type, etc.  I haven't
figured them out yet.

The main reason of porting to the Mac OS (so far) is to compare Chaco
against Quartz's behavior.  They should be pretty much the same.  I
managed to get an initial test of the mac stuff working, but, after
seeing that it looked the same, I haven't maintained it.  I'm hoping
someone more comfortable on OSX will pick it up at some point.

All of that said, I think it should all still run.  As I remember, the
tests were done from the MacPython command line.  The following might

	>>> import maccore2d
	>>> maccore2d.show_all_samplers()

Sorry I can't be of more help.
