[Distutils] svn tagging setuptools command

[Ian Bicking]

Upon further thought, I think I'm forcing this into distutils.commands 
entry points unnecessarily.  --command-packages can be applied through 
the commandline or through the setup.cfg file.  I have to figure out the 
exact details, but as I remember it's not particularly difficult.

I expect I'll still want a entry point for all these that acts like 
distutils.commands, but under a different name.  Then a command-packages 
managing command (that's hard to parse ;) could use that to list 
available command packages.  The command-packages managing command 
itself would be installed globally.
