This is the plugin description
From the release page you can download the latest *.kpz file
Koha's Plugin System allows for you to add additional tools and reports to Koha that are specific to your library. Plugins are installed by uploading KPZ ( Koha Plugin Zip ) packages. A KPZ file is just a zip file containing the perl files, template files, and any other files necessary to make the plugin work.
The plugin system needs to be turned on by a system administrator.
To set up the Koha plugin system you must first make some changes to your install.
