=head1 SYNOPSIS

    % perl t/harness [options] [testfiles]

=head1 DESCRIPTION

The short command line options are:

=over 4

=item C<-w>

Turn warnings on.

=item C<-g>

Run the C<CGoto> core.

=item C<-j>

Run with JIT enabled.

=item C<-C>

Run the C<CGP> core.

=item C<-S>

Run Switched.

=item C<-b>

Run bounds checking enabled.

=item C<-d>

Run with debugging enabled.

=item C<-f>

Run fast core.

=item C<-r>

compile to Parrot bytecode and then run the bytecode.

=item C<-O[012]>

Run optimized to the specified level.

=item C<-D[number]>

Pass the specified debug bits to the parrot interpreter.  Note that 
C<-D40> (fill I, N registers with garbage) is always enabled.  
See 'parrot --help-debug' for available flags.

=back

There are also long command line options:

=over 4

=item C<--running-make-test>

Some test scripts run more quickly when this is set.

=item C<--gc-debug>

Invoke parrot with '--gc-debug'.

=item C<--html>

Emit a C<smoke.html> file instead of displaying results.

=item C<--code-tests>

Run only the file metadata and basic coding standards tests.
