Well again, the XULRunner app works!  I set up my directory structure, with
a toplevel app directory/chrome, components, etc... just the way the
tutorials describe, and everything works great.... it's when I try to import
the python xpcom libraries interactively though, ie: "from xpcom import
components" that I have the resolution issue...

I've added as many conceivable paths to my PYTHONPATH as I can imagine, as
well as started my interactive python shell from a myriad of different
locations with no luck

Is there any better material regarding how to get started with this stuff,
than the sparse examples I've found already?  Maybe this isn't the
technology to be using if it's falling into disservice?

I guess if I stick with it... are there any diagnostic tools I can pick up
to ease my headaches?  Right now I'm limited to taking my one simple
XULrunner example, and sort of permuting it to do different stuff, using
javascript alerts as my primary source of debug statements (bleck!)

I guess even beyond that, does anyone have any suggestions regarding
mozconfig files I can use to build the trunk to give me the appropriate
suite of tools for developing a standalone XUL application? (a la songbird,
etc...)  I could post mine, if that's informative.

So many questions, sorry to sort of fork the topic of this thread.
