=head2 PARAMETERS:

=head3 MANDATORY PARAMETERS

    -j --project [project]: desired project name.

=head3 OPTIONAL PARAMETERS

    -c --config [config]: configuration name to filter runs.  Can be passed multiple times.
    -s --status [status]: only list runs with one or more tests having [status] in testrail.  Can be passed multiple times.
    -e --encoding: Character encoding of arguments.  Defaults to UTF-8.
                   See L<Encode::Supported> for supported encodings.

=head3 CONFIG OPTIONS

    In your \$HOME, (or the current directory, if your system has no
    concept of a home directory) put a file called .testrailrc with
    key=value syntax separated by newlines.
    Valid Keys are: apiurl,user,password

=head3 CONFIG OVERRIDES

    These override the config, if present.
    If neither are used, you will be prompted.

  --apiurl   [url] : full URL to get to TestRail index document
  --password [key] : Your TestRail Password, or a valid API key (TestRail 4.2 and above).
