I too would like some more information on this subject.
It's been a few months since this thread started and it had no replies yet.
Personally I'd like to convert this bundle: https://github.com/masterzen/puppet-textmate-bundle
, to add Puppet syntax highlighting support.
Tried dragging and dropping the contents of the bundle inside a new directory. It shows up in the menu but when I load the syntax there's no highlighting whatsoever.
I have no clue where to begin debugging due to lack of documentation.
