[Koha] Is this plugin in use? macles.pl

There is a plugin for the MARC edit form called macles.pl, "Gestion des index MACLES" I'm assuming it's specific to UNIMARC. Does anyone know if this is still in use? It's been broken since I think version 16.05, so I'm curious whether it can be removed. Thanks, Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
