Date	Version	Description
-------	-------	------------------------------------------------------
11/1/99 5.31.3	Shlomi Mahlab <[email protected]> noted all.tcl in CVS
		but not distribution.

		More notes from Keith Brown on HP cc complaints in exp_pty.c.

10/28/99 5.31.2	"Keith Brown" <[email protected]> noted that HP cc
		objected to auto aggregate initialization in
		expLogChannelOpen.

10/22/99 5.31.1 Official release!

		P Darcy Barnett <[email protected]> noted Makefile could
		produce "autoconf not found" for non-developers using CVS.
		Made configure detect and provide advice on workaround.

		Fixed bug in interact -echo exhibited in rftp example.

		Ryan Murray <[email protected]> noted Expect wasn't
		handling handling 8-bit bytes correctly.  I had accidentally
		used Tcl_Write instead of Tcl_WriteChar.

		Ashley Pittman <[email protected]> noted that digital unix
		V5.0 prefers openpty (4000 ptys) over ptmx (60 ptys), so I'm
		reversing the login in pty_termios.c.  This also controls
		linux, but no linux hackers have weighed in on this subject
		yet.

		Andrew Tannenbaum <[email protected]> noted exp_internal
		command and "expect -exact" were broken.

6/29/99 5.31.0	See the NEWS file for this date for an overview.  (I'm
		too tired to add all the details.  Maybe later.)

		Fixed exp_clib so that it immediately reported failure of
		exec (in spawn) rather than passing it back through pipe.

		Removed error checking from ioctl(TIOCSCTTY) to pacify the
		variety of (but not all) Linux systems and a few others which
		define TIOCSCTTY but return an error although seem to work
		anyway.

		Added configure test for 0 vs 2-arg setpgrp.

		Kenji Kamizono <[email protected]> noted it was possible
		to compile Linux (2.2.5) so that it recognized both openpty
		and ptmx leading to conflicts.  I arbitrarily chose ptmx.

10/15/99 5.30.2	Herve Tireford <[email protected]> noted extraneous
		sleep(20) in clib.  Apparently left over from debugging, oops.

8/18/99 5.30.1	Added test for newer versions of Tcl that are incompatible.

		Kenji Kamizono <[email protected]> noted it was possible
		to compile Linux (2.2.5) so that it recognized both openpty
		and ptmx leading to conflicts.  I arbitrarily chose ptmx.

4/1/99	5.30.0  Martin Forssen <[email protected]> provided fix to allow configure
		to start with LDFLAGS from environment.

======================================================================
======================================================================

Date: 10/22/99

** SUMMARY

Expect 5.31 now works with Tcl 8.2.  Expect 5.31 does NOT work with
prior releases of Tcl.  Thanks to an incredible amount of work by
Scott Stanton, Henry Spencer, Melissa Hirschl, and funding from
Scriptics for making this possible.

** NEW FEATURES

What?  You mean that working with Tcl 8.2 isn't enough?????

intended for end-user consumption in interactive dialogues.

** CHANGES IN BEHAVIOR (POTENTIAL INCOMPATIBILITIES)

The interpreter command used to exit upon eof.  Now it uses "-eof
script" to control this behavior.  The default behavior is to return.
(This change was required because Expect now gives control to Tcl upon
exit and Tcl waits (potentially forever) for all processes to die on
exit.)  Explicit calls to interpreter are almost non-existent.
However, you should look for *implicit* calls via interact commands
with a pattern but no action.  This required changes in the examples:
dislocate, dvorak, kibitz, and xkibitz.

Indirect variables can no longer start with "exp".  Such variables
will be interpreted as channel names.

# Warning: Tk definitions are very similar to Tcl definitions but

# so don't do changes to Tcl thinking you can cut and paste it do 
# the Tk differences and later simply substitute "Tk" for "Tcl".
# Known differences:
#  - Acceptable Tcl major version #s is 8.2-9.* while Tk is 8.2-9.*
#  - Searching for Tcl includes looking for tclInt.h, Tk looks for tk.h
#  - Computing major/minor versions is different because Tk depends on
#    headers to Tcl, Tk, and X.
#  - Symbols in tkConfig.sh are different than tclConfig.sh
#  - Acceptable for Tk to be missing but not Tcl.
