I'm always wary of adding non-standard functionality to PyOpenGL, but as I've been trying to write tutorials for how to use shaders I'm finding that it really is necessary to have a module that provides the appropriate "alternate" definitions and provides the basic compileShader/compileProgram functions (with error checking and log extraction).

So, to use a shader in PyOpenGL (in the 3.0.1 upcoming release):

from OpenGL.GL.shaders import *
...
	self.shader = compileProgram(
		compileShader(
		'''void main() {
			gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;
			gl_FrontColor = gl_Color;
		}''',GL_VERTEX_SHADER),
		compileShader('''void main() {
			gl_FragColor = gl_Color;
		}''',GL_FRAGMENT_SHADER),
	)
...
	glUseProgram(self.shader)

I'm sure I'll regret it as soon as the comments start, but oh well, the folly of youth.
