 * so that you can output your own ad-hoc debugging info.
 * However, if you use stderr diretly, please delete calls to it once
 * you finished debugging so that it won't clutter up.
 * Also use TRACE_ENABLE to turn off output of any debugging info
 * when compiling for a gui front-end so that running gui won't generate
 * output on command line
