=head1 list-dropbox-files.pl

Lists all files under a Dropbox path.

This command lists all files under a path owner by the cloud storage account
currently configured for use by Virtualmin, specified by the C<--path> 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.
