20    <para>Dropbear is a relatively small SSH 2 server and client. Dropbear has a small
21     memory footprint suitable for memory-constrained environments, while still having
22     the same features as OpenSSH. It does not depend on OpenSSL and it has a MIT
23     style license. Optionally it can even be made smaller.
