>Subject: [PATCH] Bug 30484: Implement support for ILL request updates
>
>This commit adds support for the concept of ILL request update notices.
>
>- Adds a new Koha::Illrequest::SupplierUpdate class that is used to
>encapsulate an update to a request, this update may come from a
>supplier via a backend or from core ILL via, perhaps, a user action
>- Adds a new Koha::Illrequest::SupplierUpdateProcessor base class that
>can be subclassed in order to create a processor that can be passed an
>update and act accordingly.
>- Updates to Illrequest.pm to support the above classes and allow core
>Koha to offer update processors
>- A shell script to initiate a periodic process to check for updates
>meeting given criteria and run the appropriate processors
