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