 The options that can be passed to the program are as follows:
 
--p, --print-nodes
+-p, \--print-nodes
   Prints the before and after node status, in a format designed to allow
   the user to understand the node's most important parameters. See the
   man page **htools**(1) for more details about this option.
 
--t *datafile*, --text-data=*datafile*
+-t *datafile*, \--text-data=*datafile*
   The name of the file holding cluster information, to override the data
   in the JSON request itself. This is mostly used for debugging. The
   format of the file is described in the man page **htools**(1).
 
---simulate *description*
+\--simulate *description*
   Backend specification: similar to the **-t** option, this allows
   overriding the cluster data with a simulated cluster. For details
   about the description, see the man page **htools**(1).
 
--S *filename*, --save-cluster=*filename*
+-S *filename*, \--save-cluster=*filename*
   If given, the state of the cluster before and the iallocator run is
   saved to a file named *filename.pre-ialloc*, respectively
   *filename.post-ialloc*. This allows re-feeding the cluster state to
