stdwin
On Unix running X11, it can only be used if the DISPLAY
environment variable is set or an explicit `-display
displayname' argument is passed to the Python interpreter.
Functions have names that usually resemble their C STDWIN counterparts with the initial `w' dropped. Points are represented by pairs of integers; rectangles by pairs of points. For a complete description of STDWIN please refer to the documentation of STDWIN for C programmers (aforementioned CWI report).
