This package ships several plugins. To use them, you need to enable them by
adding them to $rcmail_config['plugins'] array in your
`/etc/roundcube/main.inc.php' file.

Some plugins need to be configured directly in `/etc/roundcube/main.inc.php'
while some others have specific configuration files. For the later, look at
`/etc/roundcube/plugins'. You will find empty files that you can modify to
configure the corresponding plugin.
