From 045880fb3602540472b3760832a73b431514bb7f Mon Sep 17 00:00:00 2001 From: Benjamin Poirier Date: Wed, 18 Nov 2009 10:51:40 -0500 Subject: [PATCH] Unify ltt-armall* scripts Adds switches to ltt-armall to control locking-related and network-related marker activation (off by default). Modifies ltt-disarmall to simply disconnect all active markers (and no more).
