Usage: perl Makefile.PL <options>

Possible Options are:

  --verbose     Enable verbose mode
  --noprompt    Disable interactive dialog

  --test-dsn=dsn        Sets data source for testing.  Uses dbi:mysql:test
                        by default.
  --test-user=user      Username and password to use with the dsn above
  --test-pass=password  during testing.  They both default to undef.
