Nicholas, Has,
thanks a lot for bringing me up to speed!
the help functions didnt all work for me, and I completely missed
htmldoc.py, so I was flying blind....
e.g. quicktime.can_export.help() results in errors for me (using
apples tiger pythonw)
========================================================================

Appscript Help (-t)
Reference: app(u'/Applications/QuickTime Player.app').can_export

but now, thanks to htmldoc.py, I have the full quicktime help anyway
thanks again!
