USAGE_TEXT="Usage: crm_failcount <command> [<options>]
Common options:
--help Display this text, then exit
--version Display version information, then exit
-V, --verbose Specify multiple times to increase debug output
-q, --quiet Print only the value (if querying)
Commands:
-G, --query Query the current value of the resource's fail count
-D, --delete Delete resource's recorded failures
Additional Options:
-r, --resource=value Name of the resource to use (required)
-n, --operation=value Name of operation to use (instead of all operations)
-I, --interval=value If operation is specified, its interval
-N, --node=value Use failcount on named node (instead of local node)"
