I need to know when a user opens a file.

1. Python process that is constant
2. File is *checked in* through perforce and is not writable
3. The file is opened using one of several programs.
ex. Can be accessed through Photoshop, paint ets
4. When the user opens the file or a file in a directory - python can then say hey are you wanting to check that out in perforce

Problems: Only ask...
