19.18. Short Options #

   For convenience there are also single letter command-line option
   switches available for some parameters. They are described in
   Table 19.5. Some of these options exist for historical reasons, and
   their presence as a single-letter option does not necessarily indicate
   an endorsement to use the option heavily.
