[TextMate] Handling file extensions

I installed Lars Pind's OpenACS bundle (http://pinds.com/blog/one-entry?entry%5fid=20990) and started playing around with it a bit. I noticed that for some reason TM can't open the files (with extensions adp, tcl and xql) from the project drawer. With normal open command they opened nicely.

I fixed this by adding the extensions to Info.plist file in TextMate application folder, but I fear it gets replaced when upgrading. Besides, I guess there's (or should be) a way a bundle developer could add file extensions TextMate (with a given bundle) can handle. Any pointers on how to obtain this?

TIA, Jarkko
