=head1 download-rs-file.pl
Downloads a single file from a Rackspace container.
This command downloads a file to your Virtualmin system from Rackspace's Cloud
Files service. 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.
The C<--container> flag must be given to specify the container the file is
stored in, the C<--dest> flag to choose the file to file, and the C<--file>
flag to set the source filename.
