+#!/bin/bash
+#
+# Plugin to monitor CPU usage, for a selected set of users
+#
+# Usage: Place in /etc/munin/node.d/ (or link it there  using ln -s)
+#        Add this to your /etc/munin/plugin-conf.d/munin-node:
+#		[cpubyuser]
+#		env.USERS root yann
+#
+#	 root and yann being a list of the users to monitor.
+#	 You need to also make sure that awk is installed
+#
+# 2008-12-08 v 1.3.1 Hanisch Elián:
+#				- support for dots in user names.
+#				- fix labels
+#
+# 2008-12-01 v 1.3 Hanisch Elián:
+#				- fixes, refactoring and code cleanup
+#				- Users that use cpu but aren't in the USERS env var
+#				are plotted as "others", set others.graph to 'no' if
+#				you	don't want this.
+#
+# 2008-03-20 v 1.2 fireball:	fixed minor screwup, works now ^^
+#
+# 2008-01-09 v 1.1 fireball:	fixed "-" in usernames, those get replaced by "_" now.
+#				set usernames in config accordingly (that is with _)
+#
+#
+# Parameters understood:
+#
+#       config   (required)
+#       autoconf (optional - used by munin-config)
+#
+
+#%# family=auto
+#%# capabilities=autoconf
