Usage: $PROGNAME [options]
Run the emugen test suite. This scripts looks for sub-directories
named t.<number>/input, and uses them as input to 'emugen'. It then
compares the output to t.<number>/expected/ content.
Valid options:
--help|-h|-? Print this help.
--out-dir=<dir> Generate outputs into <dir>.
--emugen=<program> Emugen program path, if not in path.
--tool=<tool> Launch visual diff tool in case of differences.
