[NEW PORT] shells/zoidberg: A modular PERL shell

        A modular Perl shell written, configured, and operated
        entirely in Perl. It aspires to be a fully operational login
        shell with all the features one normally expects. But it
        also gives direct access to Perl objects and data structures
        from the command line, and allows you to run Perl code
        within the scope of your command line.
