sorladmin_script.pl

#!/usr/bin/env perl

use FindBin;
use local::lib "$FindBin::Bin/../local-lib";
use lib 'lib';

#use Solr::Admin::Web;

use Web::Simple 'Solr::Admin::Web';

package Solr::Admin::Web;

sub dispatch_request {
    my($self) = @_;

    sub (GET) {
        [ 200, [ 'Content-type', 'text/plain' ], [ 'Result!' ] ]
    },
}

Solr::Admin::Web->run_if_script;
