    <para>Dropbear is a relatively small SSH server and client. Dropbear has a small
     memory footprint suitable for memory-constrained environments, while still having
     the same features as OpenSSH. It does not depend on OpenSSL and it has a MIT
     style license.</para>

    <para>Dropbear depends on zlib.</para>
