/*
Input used to generate the Python module "glmodule.c".
The stub generator is a Python script called "cgen.py".

Each definition must be contained on one line:

<returntype> <name> <type> <arg> <type> <arg>

<returntype> can be: void, short, long (XXX maybe others?)

<type> can be: char, string, short, float, long, or double
	string indicates a null terminated string;
	if <type> is char and <arg> begins with a *, the * is stripped
	and <type> is changed into string

<arg> has the form <mode> or <mode>[<subscript>]
	where <mode> can be
		s: arg is sent
		r: arg is received		(arg is a pointer)
	and <subscript> can be (N and I are numbers):
		N
		argI
		retval
		N*argI
		N*I
		N*retval
	In the case where the subscript consists of two parts
	separated by *, the first part is the width of the matrix, and
	the second part is the length of the matrix.  This order is
	opposite from the order used in C to declare a two-dimensional
	matrix.
