[TxMt] env variable to get all project files?

[kumar mcmillan]

I vaguely recall this question coming up but I wanted to re-emphasize 
it.
There is currently no way for a command to operate on all files 
contained in a project [or is there?].  there is TM_PROJECT_DIRECTORY 
but this is only a path to where <project>.tmbundle lives.  Allan do 
you have plans for adding this soon?

Some motivations for such a request :
Another developer and I would like to work on some eclipse-style 
refactoring tools [ 
http://www-128.ibm.com/developerworks/library/os-ecref/ ] but there 
would have to be a way to access all files in a project.  Also, the one 
reason holding me back from using the Subversion bundle [almost] 
exclusively is its inability to commit all files in a project.
