Add 'use strict' and fix make_opengl accordingly.
Add function prototypes. Write "$a $b" rather than the more complex $a . " " . $b. Document which OpenGL spec files need to be downloaded. Update the documentation of the list of supported OpenGL versions. Tweak the usage so it always reports the right command name.
