=head1 NAME

TestRail::API - Provides an interface to TestRail's REST api via HTTP

=head1 SYNOPSIS

    use TestRail::API;

    my $tr = TestRail::API->new($username, $password, $host);

=head1 DESCRIPTION

C<TestRail::API> provides methods to access an existing TestRail account using API v2.  You can then do things like look up tests, set statuses and create runs from lists of cases.
It is by no means exhaustively implementing every TestRail API function.
