Mono.Addins is a framework for creating extensible applications, and for
creating libraries which extend those applications.

Mono.Addins has been designed to be easy to use and useful for a wide range
of applications: from simple applications with small extensibility needs, to
complex applications which need support for large add-in structures.

This new framework intends to set an standard for building extensible
applications and add-ins in Mono.

Requires Mono and Gtk-Sharp, available at SlackBuilds.org
