Overview

****************************************************************************************************** Plugin registry maintaining the plugins of a gem. ****************************************************************************************************** A plugin must have a name according convention:

|plugin-gem-name| = |target-name|plugin-entity|plugin-type|

|--- plugin-name ---------|

Eg: “pizza-stone-oven” and “pizza-electric-oven” could be two “oven” plugins for a “pizza” gem

A plugin must also have a certain layout with a plugin-file in it’s installation folder:

[plugin-gem-home]/lib//plugin.rb

Where plugin.rb will provide a plugin-loader to create the plugin’s runtime object ******************************************************************************************************
