How about 'tmt'?
I like it.
... it didn't have a quick to type name like 'cvs', or 'svn'. Three characters or less seems to be my personal tolerance before I start to get annoyed.
Well, actually I'm a bit incapable of typing both svn and the svn command that follows correctly, so I alias svn as 7, and then I can have lots of fun typing "7 up".
