Installing Plugin
=================
Simply untar the file in the plugins directory, and make sure it is
in its own directory, and that the name of the directory is the name
of the plugin. For example:

  $ cd /var/www/squirrelmail/plugins
  $ tar -zxvf /home/archives/limit_languages-1.0-1.4.0.tar.gz

Then go to SquirrelMail config directory and run conf.pl. Choose option
8 and enable the plugin.

  $ cd ../config
  $ ./conf.pl

Save configuration changes and exit.

Plugin's configuration is stored in config/limit_languages_config.php
or plugins/limit_languages/config.php. If both files are missing, plugin
uses default configuration, languages are not filtered and error message
is displayed in message listing. If both files are present, plugin uses 
values from config/limit_languages_config.php

See available configuration options in 
plugins/limit_languages/config_default.php.
