The functionalities of manitou-mdx can be extended by writing Perl modules that are hooked to manitou-mdx as plugins. A plugin module may be a self-contained piece of code, but more often it's used as an interface to an external program, such as a spam filter or a converter that extracts text from a complex file format. Also, plugins may use external Perl modules from the CPAN archive or other sources.
