Thanks for the response.

That will help quite a bit, for things like making #include guards in my C
bundle. But for some other things, I'd like to be able to share across
bundles (eg. copyright notices). I suppose I could do something like that by
just putting it in the TM_SUPPORT folder instead of the TM_BUNDLE_SUPPORT?

I do know a little Ruby... Is it just Ruby that's supported, or any
scripting language?

Thanks again,
