=head1 list-gcs-files.pl
Lists all files in a Google Cloud Storage bucket.
This command lists all files in a bucket under the cloud storage account
currently configured for use by Virtualmin, specified by the C<--bucket> flag.
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.
