# do work:
use Qudo;
my $qudo2 = Qudo->new(
    driver_class => 'Skinny', # optional.
    databases => [+{
        dsn      => 'dbi:SQLite:/tmp/qudo.db',
        username => '',

DESCRIPTION

Qudo is simple and extensible job queue manager system.

Your application can insert job into DB ,that is managed by Qudo. And Your application can get & execute job by Qudo worker. Qudo corresponds to deal with DB as MySQL and SQLite.

If you add Hook Point around job's working method , you can add it easily and many point of work milestone. Qudo is consided about adding Hook Point Flexibility.
