From ecb483c282d48a6236c2aafd3beaa355e5a75e73 Mon Sep 17 00:00:00 2001 From: José Bollo Date: Mon, 7 Aug 2017 17:20:37 +0200 Subject: afm-binding: provide afm as a unique binding MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is the first stone (not fully tested) to implment the afm-main as a binding. At the end, this component will replace afm-user-daemon and afm-system-daemon.
