Alfredo,

I used to have a simple test harness that read in some test
page source from a file and called ReplaceInlineAxiom. That is
very simple but you have to comment-out any reference to the
Zope environment (one one case I think). If you like, I can
take a look for it and send you a copy.

But now that I have tried iPython interactive shell for Python
- motivated by the fact that Sage uses a customized version of
iPython for it's command line interpreter - I would say that
is definitely a better way to fly!

Not that I know of. Almost a year ago! I did try running Axiom
inside fbrun and it seemed to work as I described. This is one
of those projects that I was hoping to get to real-soon-now. :)

Hmmm... Well as I recall I did get so far as installing X-windows
with Xfbdev on axiom-developer.org but its been too long since
I did anything with this so I don't recall much more about it.

More later, gotta run.
