/*---------------------------------------------------------------------------

Automated test of the DMAPI functions dm_set_region() and dm_get_region().

The command line is:

        test_region [-s sid] ls_path directory 

where 
   pathname
      is the name of a file
   ls_path
      is the path to a specific copy of ls, important only for its size
   sid
      is the session ID whose events you you are interested in.
