+=head1 NAME
+
+RemoteSite::FTP::Experimental.pm - Access a remote FTP site.
+
+=head1 DESCRIPTION
+
+C<RemoteSite::FTP::Experimental> is inherited from the abstract base class C<RemoteSite>, implementing the abstract methods required for transfer of files to and from a remote site when the remote site is an FTP server.
+
+This class differs from C<RemoteSite::FTP> only in using a different mechanism for listing the contents of directories on FTP sites.
