+#!/bin/bash
+# Script written by @srepac as requested by @Mark Jim
+# This script perform uninstall of pikvm from raspbian.  This performs the following:
+#
+# 1. Stop/disable kvmd services
+# 2. Remove the main kvmd package files based on what was installed (see /var/cache/kvmd/installed_ver.txt file)
+#
+# CAVEATS:
+# 1. Script does not remove /usr/bin/ttyd (webterm), /usr/bin/ustreamer, /usr/bin/ustreamer-dump
+# 2. Script does not remove /usr/bin/janus (webrtc) and all its dependent files also
+# 3. Script does not remove any directories; you may end up with empty directories
+###
+# CHANGELOG:
+# 1.0	20220218	created script
+# 1.1	20220220	confirm uninstall and add -f option to perform destructive commands
+# 1.2   20220225	restore original /etc/motd
+# 2.0   20220225	save custom configs for possible restores during re-install later
+VER=2.0
