+#
+# Munin plugin to monitor Tor traffic
+#
+# Author: Ge van Geldorp <ge@gse.nl>
+#
+# Parameters understood:
+#
+# 	host       - Change which host to graph (default localhost)
+# 	port       - Change which port to connect to (default 9051)
+#	password   - Plain-text control channel password (see torrc
+#	             HashedControlPassword parameter)
+#	cookiefile - Name of the file containing the control channel cookie
+#	             (see torrc CookieAuthentication parameter)
+#
+# Using HashedControlPassword authentication has the problem that you must
+# include the plain-text password in the munin config file. To have any
+# effect, that file shouldn't be world-readable.
+# If you're using CookieAuthentication, you should run this plugin as a user
+# which has read access to the tor datafiles. Also note that bugs in versions
+# upto and including 0.1.1.20 prevent CookieAuthentication from working.
+#
+# Usage: place in /etc/munin/node.d/ (or link it there using ln -s)
+#
+# Parameters understood:
+# 	config   (required)
+# 	autoconf (optional - used by munin-config)
+#
+#
+# Magic markers - optional - used by installation scripts and
+# munin-config:
+#
+#%# family=contrib
+#%# capabilities=autoconf
