=head1 NAME

rt-server - RT standalone server

=head1 SYNOPSIS

    # runs prefork server listening on port 8080, requires Starlet
    rt-server --port 8080

    # runs prefork server listening on port 8080 at /rt
    rt-server --port 8080 --webpath /rt

    # runs server listening on port 8080
    rt-server --server Standalone --port 8080
    # or
    standalone_httpd --port 8080

    # runs other PSGI server on port 8080
    rt-server --server Starman --port 8080

=head1 DESCRIPTION

The C<rt-server> utility uses Plack so you can pass through additional
options described in the L<plackup|https://metacpan.org/pod/distribution/Plack/script/plackup>
documentation. For example, if you want to see server logs when developing,
you can start the server like:

    sbin/rt-server --env development --access-log var/access.log

Log output will then go to var/access.log.
