 =head1 DESCRIPTION
 
-The B<mkrrnodes> command is a sample tool that adds or deletes (-d) nodes according to a specific
-naming convention.  You can input the connected unit name (CU, a subset of the cluster, usually in its own
-subnet and managed by an xCAT service node) using the -C flag, and you can input the start and end
-range using the -R flag. It will also automatically define required nodegroups.
-
-In this example tool, the node names will have the format:
-
-B<rr>I<x048y>
-
-where:
- x is a-z, indicating the CU name
- 048 is the node number within that CU
- y is a-c, indicating which of 3 blades within the "triblade" group it is
+The mkrrnodes add or delete (-d) the nodes requested by inputting the CU name (-C) flag and the start and end range (-R) flag.  It will also automatically define required nodegroups.
