[Cluster-devel] [PATCH] fence_rackswitch: Add metadata output for fence_rackswitch agent

[Marek 'marx' Grac <mgrac@redhat.com>]

Adding this feature allow us to generate manual pages directly from XML,
so both GUI tools and manual pages can see same feature.

Resolves: rhbz#714841 (partial)

-.SH NAME
-fence_rackswitch - I/O Fencing agent for RackSaver RackSwitch
-
-.SH SYNOPSIS
-.B
-fence_rackswitch
-[\fIOPTION\fR]...
-
-.SH DESCRIPTION
-fence_rackswitch is an I/O Fencing agent which can be used with the RackSaver 
-RackSwitch.  It logs into the RackSwitch and boots a specified plug.
-Using the http interface to the RackSwitch should be avoided while a GFS cluster is 
-running because the connection may interfere with the operation of this agent.
-
-fence_rackswitch accepts options on the command line as well as from stdin.  
-fenced sends the options through stdin when it execs the agent.  fence_rackswitch 
-can be run by itself with command line options which is useful for testing.

-Vendor URL: http://www.bladenetwork.net
