  Lire::PluginManager->register_default_plugins();

  my $plugin = new MyDlfConverter();
  Lire::PluginManager->register_plugin( $plufin );

  my $plugins = Lire::PluginManager->plugins( 'dlf_analyser' );

  my $converter = Lire::PluginManager->get_plugin('dlf_analyser', 'combined');

All method can be called as class method on the Lire::PlugingManager module or on an instance.

There are four kind of plugins defined in Lire: dlf_analyser, dlf_converter, chart_type and output_format.

The type and name of the plugin are queried using the Lire::Plugin interface. An error will be thrown if there is already a plugin registered under the same name and type. Unregister the plugin CW$name of type CW$type. The method will dies if there is no such plugin. Returns in an array reference all the analysers that declare CW$schema as their src_schema(). Returns in an array reference all the analysers that declare CW$schema as their dst_schema().

This method will load and initialize all the plugins available. The plugins are registered by executing all the perl scripts found in the directories listed in the 'plugins_init_path' configuration variable.

These scripts should call Lire::PluginManager->register_plugin() to register the plugins.

For compatibility with previous versions of Lire, it will also registers the DlfConverters initialized using older mechanism.
