/*
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.
