  You might want to read the section of the comp.unix.questions FAQ which
discusses why shell scripts can't change their parents' environments.  Unless
you're planning on making this a file that people "source", rather than
running as an executable shell script.

  If you don't have a copy of the FAQ and it has expired at your site, see the
end of this message for instructions on how to get it.
