GLSL low level compiled shader object - this class is used to get at the linked program object and provide an interface for GLRenderSystem calls. GLSL does not provide access to the low level code of the shader so this class is really just a dummy place holder. GLSL uses a program object to represent the active vertex and fragment programs used but Axiom materials maintain seperate instances of the active vertex and fragment programs which creates a small problem for GLSL integration. The GLSLGpuProgram class provides the interface between the GLSLLinkProgramManager , GLRenderSystem, and the active GLSLProgram instances.
