Detailed Description

This ResourceManager manages GPU shader programs.

This class not only manages the programs themselves, it also manages the factory classes which allow the creation of programs using a variety of syntaxes. Plugins can be created which register themselves as program factories and as such the engine can be extended to accept virtually any kind of program provided a plugin is written.
