"""Simple svn commit wrapper which emails a given list of people.

Usage:

  ipsvnc [args]

This is equivalent to doing

  svn commit [args]

If the commit operation is successful (the script asks for confirmation), a
hardwired list of maintainers is informed of the commit.

This is a poor-man's substitute for a proper svn post-commit hook with an
ipython-svn email list, which we're waiting to get soon.  It should be removed
once that facility is in place.

This only works on a unix box which can send mail by itself."""
