I was thinking it would make sense to grab the doc from the class that
handles the options for the particular subcommand, since it is the only
class/function that we already know the name of and that is already
associated with the subcommand.

class RmvobOptions(usage.Options):
	"""Remove a VOB, yada yada yada <<< Here's my doc to go into usage
	"""
	optParameters = [
		['vobs', 'v', None, "Comma-delimitted list of VOBs to remove"],
		['original', 'o', None, "Site to remove VOBs from"],
	]
	def postOptions(self):
		for opt in ["vobs","original"]:
			if not self[opt]:
				raise usage.UsageError, "--vobs and --original are required."

Does that make sense?  Is that something you can do, or should I get
familiar with the code and submit a patch?
Thanks for your other suggestions as well.
