=head2 MANDATORY PARAMETERS

=over 4

--apiurl     : full URL to get to TestRail index document

--user       : Your TestRail User Name.

-j --project : desired project name.

-t --testsuite  : desired testsuite name to search for cases within.  May be passed multiple times.

-d --directory : directory to search for tests to correlate with TestRail cases.  May be passed multiple times.

=back

All mandatory options not passed with the above switches, or in your ~/.testrailrc will be prompted for.

=head2 SEMI-OPTIONAL PARAMETERS

=over 4

-m --missing : Only show cases which are in the directory passed, but not TestRail.  Mutually exclusive with orphans.

-o --orphans : Only show cases which are in TestRail, but not the directory passed.  Mutually exclusive with missing.

-n --no-recurse : do not recurse subdirectories when considering what tests need adding/updating/pruning.

-e --encoding   : Character encoding of arguments.  Defaults to UTF-8. See L<Encode::Supported> for supported encodings.

=back

=head1 CONFIGURATION FILE

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.
