+
+=head1 NAME
+
+multimemory - Munin plugin to monitor memory usage of processes. Which processes
+are configured in client-conf.d
+
+=head1 APPLICABLE SYSTEMS
+
+Any system with a compatible ps command.
+
+=head1 CONFIGURATION
+
+There is no default configuration.  This is an example:
+
+  [multimemory]
+	 env.os freebsd
+     env.names apache2 mysqld php-cgi
+
+Set env.os to freebsd if you are running this script on a machine which doesnt have
+GNU sed installed (FreeBSD / OpenBSD / Solaris ...), else set it to linux.
+
+The names are used to grep with directly, after cleaning. So, this plugin
+only supports very basic pattern matching. To fix: see multips
+
+=head1 INTERPRETATION
+
+This plugin adds up the RSS of all processes matching the
+regex given as the process name, as reported by ps.
+
+=head1 MAGIC MARKERS
+
+  #%# family=manual
+  #%# capabilities=autoconf
+
+=head1 VERSION
+  0.3 light improvement in FreeBSD part of ps parsing
+  0.2 second release, it should now work on machines without GNU sed
+  0.1 first release, based on:
+    multimemory.in 1590 2008-04-17 18:21:31Z matthias
+  As distributed in Debian.
+
+=head1 BUGS
+
+None known
