o Add the -foreground switch. This switch behaves like -background except

  that ppp stays in the foreground.
o Add the -quiet switch to quieten ppps startup
o Add the -nat flag and discourage the use of the -alias flag.  Both do
  the same thing.
o Correct some nat usage strings.
o Change the internal ``alias'' command to ``nat''.
