You can install this using in the usual Perl fashion:

        perl Makefile.PL
        make
        make test
        # (or) env MQHOST="localhost" make test
        make install

The documentation is in the module file. Once you install the file, you can read it with perldoc.

perldoc Net::RabbitMQ

If you want to read it before you install it, you can use perldoc directly on the module file.

perldoc RabbitMQ.pm
