Hey Fernando.   I actually broke down and started using ipython
instead of pyCrust recently, despite my dislike for being stuck in the
lame Windows console.  It is a great shell, (love the ? and "func arg"
--> "func(arg)" features).  Just sad that it's locked into text mode.
Hopefully the ipython1 project will keep moving along so we can have
ipython in a GUI before long.

As for its debug console ability, I wasn't aware of that.  I knew you
could have it trigger the debugger at a breakpoint, but then you drop
into a prompt with debugger syntax rather than normal python syntax,
right?  So you have to prefix every command with something.  Is there
some other mode that I'm not aware of that gives you a regular

No gui also means setting breakpoints by line number or function name, no?
