1. Combined verify_ps_directories and verify_nps_directories into a
   single verify_directories eliminating the conditional.
2. Left the "double check" in place as it does not hurt anything and
   does allow for a secondary validation before proceeding.
3. Kept the sleep.  Its purpose and there are several more in the code
   to slow down the scrolling of the output allowing the user to
   actually see what occurred.  There are no synchonization issues
   associated with it.  Just user friendliness.  It is an install,
   not a production process and therefore does not require being
   all that efficient.
