# $1 = location of Xyce binary
# $2 = location of xyce_verify.pl script
# $3 = location of compare script
# $4 = location of circuit file to test
# $5 = location of gold standard prn file

# If Xyce does not produce the appropriate output files, then we return exit code 14.
# If Xyce succeeds, but the test fails, then we return exit code 2.
# If the shell script fails for some reason, then we return exit code 1.

# responsible for capturing any error output from Xyce and the STDOUT & STDERR
# from the comparison program.  The outside script, run_xyce_regression,
# expects the STDERR output from Xyce to go into $CIRFILE.err, the STDOUT
# output from comparison to go into $CIRFILE.prn.out and the STDERR output from
# comparison to go into $CIRFILE.prn.err.
