+
+
+ This tool will build a directory of files for each defined 
+ nodegroup in xCAT.  The file will be named the nodegroup name and 
+ contain a list of nodes that belong to the nodegroup. 
+ The file can be used as input to the AIX dsh command run in the DSH 
+ context.
+ The purpose of this tool is to allow backward compatiblity with scripts 
+ that were created using the AIX or CSM dsh command.
+
+
+ groupfiles4dsh  -p <directory to place generated nodegroup files> 
+ example: groupfiles4dsh -p /tmp/dshnodegrpfiles
+
+  Use:   export DSH_CONTEXT=DSH  ( default unless CSM is installed)
+		 export DSH_NODE_RSH=/bin/ssh   (default is rsh)
+		 export DSH_NODEGROUP_PATH= /tmp/dshnodegrpfiles
+         
+		 dsh  -N all  date  ( all is a group in xCAT)
+		 dsh -a date   ( see man dsh,  DSH context)
