Older notes, pruned but left here for reference...
Anyone have any good help on how to use scripted documents on MacOS (pre-X I guess... MacOS X should work the same way as other OSes with regards to launching apps, right?)
What LV has found is that if you start up a MacOS tclkit, then do a source of the scripted document, then you come close to getting things to work. The missing step is that currently at least, there is a missing environment variable which you need to set before sourcing the scripted document. That step is to do something like:
set $::env(PATH) "."
