# This is a CGI script to present a form in which to change a password.

# This form doesn't actually have to be written as a CGI script,
# however, it is done so here to demonstrate the procedures described
# in the Tcl '96 paper by Don Libes.  You can find this same form
# written as static html in the example directory of the Expect
# package.

    # lines - cookie use here is simply a convenience for users.
