 * This is a template for creating your own window drivers for Squeak:
 * 
 *   - copy the entire contents of this directory to some other name
 *   - rename this file to be something more appropriate
 *   - modify acinclude.m4, Makefile.in, and ../vm/sqUnixMain accordingly
 *   - implement all the stubs in this file that currently do nothing
 *
