Ogre assumes that there are separate programs to deal with but GLSL has one program object that represents the active shader objects during a rendering state.
GLSL shader objects are compiled separately and then attached to a program object and then the program object is linked. Since Ogre can only handle one program being active in a pass, the GLSL Link Program Manager does the same. The GLSL Link program manager acts as a state machine and activates a program object based on the active programs. Previously created program objects are stored along with a unique key in a hash_map for quick retrieval the next time the program object is required.
