Foswiki Contribs 
Extensions to Foswiki that are not 
System.plugins
  Overview 
The term "Contrib" is used to refer to any package that is not just a simple plugin. 
Foswiki contribs may 
-  extend the functionality of Foswiki, in a lower-level way than plugins,
-  or provide alternative implementations for sections of the Foswiki core e.g. user management, or when an extension just can't be implemented as a plugin because it requires very close access to Foswiki internals,
-  or they might provide other files that Foswiki uses, for example language files,
-  or they might be packages of topics that implement a "Wiki Application", using the wiki macro language, TML.
