The original message is:
./main.py -wdghf
usage: main.py [-h] [--config-file CONFIG_FILE] [--output-dir
OUTPUT_DIR] [-t TIMEOUT] [-v] [-s] [--tarball TARBALL]
[--compile-timeout COMPILE_TIMEOUT] [--test-suite TEST_SUITE
[TEST_CASES ...]] [--re-run RE_RUN]
main.py: error: unrecognized arguments: -wdghf

So this is what's confusing. I guess it doesn't mention that the user
should use the help argument and that's where the confusion was? From
my point of view that's just standard (to run a command with -h in
case of an error such as the one above), but maybe it is better to
state it explicitly.
