   #  Use Getopt::Long to parse the parameters of the program.
   #
   #  Return value is a list consisting of:
   #    A 'command' which is one of:
   #       push   - table push requested.
   #       reinit - reinit requested.
   #   Additional parameters as follows:
   #       for push: Tablename, hostname
   #       for reinit: Appname  hostname
   #
   #   This function does not validation of the parameters of push and
   #   reinit.
   #
   #   returns a list.  The first element of the list is the operation name
   #   (e.g. reinit or push).  The second element is the switch parameter.
   #   for push, this is the table name, for reinit, this is the process name.
   #   Additional elements of the list are the command argument.  The count of
   #   command arguments is validated, but not their semantics.
   #
   #   returns an empty list if the parse fails.
