Custom Policy implementation is done using a script file plug-in written in Perl.

The following qb.conf parameters must be set appropriately:

supervisor_policy_binding = Perl

supervisor_policy_library = path_to_script

To create a new custom supervisor policy, the developer must create a Perl module with the following Perl subroutines:

1. qb_init()
2. qb_approve_modify($oldjob, $newjob, $user)
3. qb_approve_submit($job)
4. qb_calcstatus($subjobstatus, $agendastatus)
5. qb_sudo_admin($username, $job)

A function, if not defined will, automatically be overridden with the "Default Policy".

Here are details on each subroutine.
