+=head1 NAME
+
+ipmi_ - Plugin to monitor temperature or fan speed using IPMI
+
+=head1 CONFIGURATION
+
+On FreeBSD make sure sysutils/ipmitool is installed. The command 
+should run as "root". Please make sure plugin configuration file is 
+modified accordingly.
+
+[ipmi_*]
+user root
+
+=head2 ENVIRONMENT VARIABLES
+
+This plugin does not use environment variables
+
+=head2 WILDCARD PLUGIN
+
+This plugin should be linked as ipmi_temp or ipmi_fans, and will show
+either temperatures or fan speeds based on its link name.
+
+=head1 NOTE
+
+WARNING: Munin has a 10 second default timeout on plugins.  On some
+hosts IPMICMD takes longer than that to probe all your hardware.  In
+this case this plugin us unusable.
+
+DELL machines return Fan speed in RPM, while HP machines reflect it as
+percent. This plugin detects and configures graphs correctly.
