=head1 list-s3-accounts.pl

Lists all S3 Virtualmin accounts.

This command lists all S3 accounts registered with Virtualmin.

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 access keys, use the C<--name-only> flag.
