+=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.names apache2 mysqld php-cgi
+
+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.
