Koha/C4/Review.pm
rangi 9796fc3b87 A work in progress still.
This module is for dealing with user submitted reviews of items
Currently it allows (with some scripts) a user to review any item on their reading record.
The review is marked unvetted, and a librarian must vette and approve the review before it can show to the public

The scripts to add/edit a review, and to display them for the opac are done.
The script to display a list of reviews waiting vetting for the librarians has also been done.
