Add purge-app parameter to evolve command

Review Request #1621 — Created May 30, 2010 and discarded


Django Evolution (deprecated)


We want a more granular way of purging applications.  In particular, we'd like to be able to purge a *particular* application, as opposed to *all* deletable applications.

The changes I've made might violate a bit of the DRY principle - I guess this is because I wanted to change as little of the original django-evolution as possible.  I imagine it's going to undergo a big refactor soon anyhow.
All of the tests in the suite currently pass.  Couldn't find a test for purge, but I've tested it manually, and it seems to work alright.  purge-app does what I need it to do.
  2. Swap these.
  3. Can you wrap to < 80 chars?
  4. We may want to check if both parameters are used, and warn the user.
  5. Blank line between these.
  6. Wrap to < 80 chars.
