ftlm_parse_sentinel: Usage Message
      ftlm_parse_sentinel [OPTIONS] TAG COMMAND
      -h                  -- Print help message.
      -v                  -- Increase output verbosity.
      -trackdisplay       -- Track display field. The display field is normally
                             used to indicate what display was used for a
                             checkout. There are cases where some vendors use
                             the display field store information that is not
                             related to the display and some cases where the
                             display contains spaces and other special
                             characters. Because of this, the display field in
                             the checkout line is ignored by default.
      Some versions of Sentinel's lsmon utility on Windows have the behavior of
      requiring the enter key to be pressed at the end of its output dump. This
      means that when executed as a background task in LicenseMonitor, the task
      will never end. If the lsmon utility being interfaced with exhibits this
      behavior, make a copy of the vovlsmon.bat script template found in
      $VOVDIR/bat and place it somewhere outside of the $VOVDIR directory.
      Modify it to point to the lsmon.exe being interfaced with, then configure
      the status command to point to this script instead of lsmon.exe directly.
      On Windows, use / for the path delimiter and // before each space if there
      are spaces in the command path.
