=head1 list-rs-containers.pl

Lists all containers owned by a Rackspace account.

This command queries Rackspace's cloud files for the list of all containers
owned by a user. The login and API key for Rackspace must be set using the
C<--user> and C<--key> flags, unless defaults have been set in the Virtualmin
configuration.

By default output is in a human-readable table format, but you can switch to
a more parsable output format with the C<--multiline> flag. Or to just get a
list of filenames, use the C<--name-only> flag.
