Hello, Thanks to everyone for your help. I thought about Tres's solution and quickly discovered that I would be doing a *lot* of clicking/typing if I wanted to upload all of the files necessary to make the ExtJS framework available. I'll look into the WebDAV idea; I didn't think of that until you mentioned it. However, I came up with another possible solution that may be generally useful after some (a lot actually) of coaxing. I threw this together in the time between my new year's festivities :) : it's incredibly sloppy at the moment, but before I worried about cleaning it up, I wanted to get some feedback from you guys about it (pardon the annoying formatting problems): def package_home(gdict): """Returns the location of the file that calls the function. You must pass it globals() as the argument for it to work right. :Parameters: gdict : dict A dictionary containing all of the global definitions for the module.

And someone could just pass ../'s to the path to get anywhere on the file system they wanted, I suppose. All of these could easily be fixed of course, but I wanted feedback before I put more than 30 minutes into the prospect :) Thanks for all your help! -Matt _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
