"""Usage: python test.py [module(s) ...]

When called without optional module names, run the test suites for
*all* modules.  This may raise lots of errors if you haven't installed
one of the versioning control systems.

When called with module name arguments, only run the test suites from
those modules and their submodules.  For example:
  python test.py libbe.bugdir libbe.storage
