+
+tentacle_client [options] [file] [file] ...
+
+=head1 DESCRIPTION
+
+B<tentacle_client(1)> is a client for B<tentacle>, a B<client/server> file transfer protocol that aims to be:
+
+=over
+
+=item    * Secure by design.
+
+=item    * Easy to use.
+
+=item    * Versatile and cross-platform. 
+
+=back 
+
+Tentacle was created to replace more complex tools like SCP and FTP for simple file transfer/retrieval, and switch from authentication mechanisms like .netrc, interactive logins and SSH keys to X.509 certificates. Simple password authentication over a SSL secured connection is supported too.
+
+The client and server (B<TCP port 41121>) are designed to be run from the command line or called from a shell script, and B<no configuration files are needed>. 
+
+If IO::Socket::INET6 is installed, the tentacle client supports IPv6.

+
+=head1 VERSION
+
+Version 0.6.1
+
+=head1 USAGE
+
+tentacle_server B<< -s F<storage_directory> >> [I<options>]
+
+=head1 DESCRIPTION
+
+B<tentacle_server(1)> is a server for B<tentacle>, a B<client/server> file transfer protocol that aims to be:
+
+=over
+
+=item    * Secure by design.
+
+=item    * Easy to use.
+
+=item    * Versatile and cross-platform. 
+
+=back 
+
+Tentacle was created to replace more complex tools like SCP and FTP for simple file transfer/retrieval, and switch from authentication mechanisms like .netrc, interactive logins and SSH keys to X.509 certificates. Simple password authentication over a SSL secured connection is supported too.
+
+The client and server (B<TCP port 41121>) are designed to be run from the command line or called from a shell script, and B<no configuration files are needed>.
