From: FAQ General information
Subject: -I- Origin of the comp.lang.tcl FAQ information.

    The information in this set of FAQs comes from several sources.  The
primary source of information is the group itself - I spend (much too
much) time each month culling through what I feel are some of the best
answers, gathering up new information on ports, etc. and adding it
here.  I also gather new application information and add it as
best I can.  The next most predominant source of information comes from
the authors of the various software packages.  Finally, a small amount
comes from my personal experiences.

    I am always on the search for folk to assist in the maintenance
of these FAQs.  In fact, if you feel that you would like to coordinate
this effort, PLEASE let me know!

------------------------------

From: FAQ General information
Subject: -II- What is Tcl?  Tk?  Extended Tcl?

    Tcl and Tk originated with Dr. John Ousterhout (Oh'-stir-hout -
last syllable rhymes with rout, not root) from the University of California,
Berkeley, California.

    Tcl (current release version 7.3) stands for ``tool command
language'' and is pronounced ``tickle.'' The author's home ftp site for
the Tcl source code is ftp.cs.berkeley.edu.  Tcl is actually two
things: a language and a library.  First, Tcl is a simple textual
language, intended primarily for issuing commands to interactive
programs such as text editors, debuggers, illustrators, and shells.  It
has a simple syntax and is also programmable, so Tcl users can write
command procedures to provide more powerful commands than those in the
built-in set.

    Second, Tcl is a library package that can be embedded in
application programs.  The Tcl library consists of a parser for the Tcl
language, routines to implement the Tcl built-in commands, and
procedures that allow each application to extend Tcl with additional
commands specific to that application.  The application program
generates Tcl commands and passes them to the Tcl parser for
execution.  Commands may be generated by reading characters from an
input source, or by associating command strings with elements of the
application's user interface, such as menu entries, buttons, or
keystrokes.  When the Tcl library receives commands it parses them into
component fields and executes built-in commands directly.  For commands
implemented by the application, Tcl calls back to the application to
execute the commands.  In many cases commands will invoke recursive
invocations of the Tcl interpreter by passing in additional strings to
execute (procedures, looping commands, and conditional commands all
work in this way).

    An application program gains three advantages by using Tcl for
its command language.  First, Tcl provides a standard syntax:  once
users know Tcl, they will be able to issue commands easily to any
Tcl-based application.  Second, Tcl provides programmability.  All a
Tcl application needs to do is to implement a few application-specific
low-level commands.  Tcl provides many utility commands plus a general
programming interface for building up complex command procedures.  By
using Tcl, applications need not re-implement these features.  Third,
extensions to Tcl, such as the Tk toolkit, provide mechanisms for
communicating between applications by sending Tcl commands back and
forth.  The common Tcl language framework makes it easier for
applications to communicate with one another.

    Tk (current release 3.6) - an extension to Tcl which provides
the programmer with an interface to the X11 windowing system.  The
author's home ftp site for the Tk source is ftp.cs.berkeley.edu.
Note that many users will encounter Tk via the ``wish'' command.  Wish
is a simple windowing shell which permits the user to write Tcl
applications in a prototyping environment.

    Extended Tcl (tclX) (Version 7.3a) - This is an extended set of
commands for Tcl developed by Karl Lehenbauer and Mark Diekhans.  The
authors' home ftp site for Extended Tcl is ftp.neosoft.com.  Extended
Tcl is oriented towards system programming tasks, with many additional
interfaces to the Unix operating system along with other useful
utilities.

From: FAQ General information
Subject: -III- Do these packages run on my machine?

A. Unix

    Tcl runs on Sun 3s and 4s running SunOS 4 and SunOS 5 (Solaris
1.x and 2.x), DECstations running Ultrix, DEC VAXen running Ultrix or
BSD, DEC Alphas running OSF/1, 386s running SCO Unix, Xenix, Bell-Tech,
Silicon Graphics running IRIX, HPs running HP-UX as well as HP Snakes
running OSF/1 and HP-UX.  Intel [34]86 systems running 386bsd, netbsd,
freebsd, BSDI, and Linux have Tcl ported.  Various CPUs running System
V.4 report having ported Tcl.  Tcl also appears to be running on
Sequent Symmetry running Dynix as well as OSF/1.  It also has been
reported to run fine on IBM RS6000 under AIX 3.x as well as IBM ES/9000
and AIX/ESA.  There were few problems getting it running under Mt. Xinu
Mach.  It also has been ported to Encore 91's running UMAX V (an 88k
based System V with BSD extension Unix).  It also runs on Apollos
running BSD/SYSV.  Tcl runs on a Cray running Unicos.  At least one
person has ported Tcl to a Mac (IIfx) running A/UX v3.0.  Someone
ported Tcl to a Sony NeWS machine running NEWS-OS 4.2.
A port to a Convex 3220 and 3880 was also reported.

    Tk (being based on Tcl) generally requires X11R4 or better as the only
additional software requirement.  It runs on any of the above Unix
systems with that base of software.  It also runs on VMS and OSF/1.

    For information on Tcl/Tk/TclX availability (see "tcl-faq/part4").


B. MacOS

    See below for details of a Macintosh Tcl Mailing list.


---

    Ray Johnson <[e-mail]> has a package called
MacTcl.  This is a fairly straight port of Tcl to the Macintosh.  It is
designed to be used as libraries to be embedded into other
applications.  A basic shell is included.  Most Tcl features are
present, including many Unix-like features.  Additional features
include supporting the env variable and sourcing Tcl code from a
resource.  The current version is available at
ftp://harbor.ecn.purdue.edu/pub/tcl/distrib/MacTcl7.3.sea.hqx

    As of this time, I have no leads on anyone porting Tk to MacOS.
I also have not heard of anyone porting Tcl/Tk to an Apple PowerPC.

    Also (see "tcl-faq/part4"), the Tcl programs/packages catalog,
for the latest port locations and versions.


C. INTEL DOS-like systems

    Numerous ports to DOS are available.  One unsupported port to MS-DOS
of Tcl and Extended Tcl V6.0a, done by "Karl Lehenbauer" <[e-mail]>,
is available on ftp://harbor.ecn.purdue.edu/pub/tcl/distrib/dostcl.zoo for
binaries and ftp://harbor.ecn.purdue.edu/pub/tcl/distrib/dostcl60.zoo for
source.

    A port of Tcl V6.2 to MS-DOS was done by
"John Martin" <[e-mail]> and is available via FTP from
ftp://cajal.uoregon.edu/pub/tcl.dos.port/ and
ftp://harbor.ecn.purdue.edu/pub/tcl/distrib/tcl62.dos.tar.Z .

    A source code only port of Tcl V6.7 to MS-DOS, done by
[e-mail] (Peter Sprenger), is available from
him, somewhere on wuarchive.wustl.edu
or as
ftp://harbor.ecn.purdue.edu/pub/tcl/distrib/tcl67dos.zip .

    A port of Tcl, version 7.3, to MS-DOS, done by
[e-mail] (Tom Poindexter), is available as
ftp://harbor.ecn.purdue/edu/pub/tcl/distrib/mstcl73*.zip .  This
also includes TclX 7.3a and Tk ported to Desqview/X libraries.

    A port of Tcl, V6.1 ?, done by unknown, to MS-DOS Windows
V 3.1 ?, is available as binary at
ftp://harbor.ecn.purdue.edu/pub/tcl/distrib/w_tclbin.zip and as source at
ftp://harbor.ecn.purdue.edu/pub/tcl/distrib/w_tclsrc.zip .

    An MS-DOS Windows DLL instance of Tcl 6.2 was generated by
Ugo Cei <[e-mail]>.  Contact him for more details.

    A Windows DLL was made by [e-mail] (Ekkehard Beier)
by slightly modifying a DOS 6.2 Tcl port.  There are still problems
with the system/WinExec command.  A very rudimentary Debugger User Interface
using Borland's Classlib is part of the zip-file, too.
I used it with BC3.1++/AF on MS W3.1.  You can get a copy from

ftp://metallica.prakinf.tu-ilmenau.de/pub/DOS/wintcl.zip

via anonymous ftp.  Unfortunately Ekki doesn't have time currently to
finish the Windows port and user Interface.

    [e-mail] (Shigeaki Miyata) reports being in a group
which is preparing a commercial port of Tk to MSDOS Windows.  More
details are to follow.

    Omar Stanford <[e-mail]> reported in March of 1994
that he had almost completed his port of Tcl 7.3 to MS-Windows 3.1.
He had incorporated extensions for networking (including NetWare),
Windows Sockets, and many Windows API functions.  He also was working on
a facility for dynamically allocating commands to the Tcl environment.
If there are other extensions that one would like to see under Windows 3.1,
or if you are interested in beta testing, drop him a line.

    Also, Simon Kenyon <[e-mail]> of the Information
Technology Centre, Dublin, IRELAND, mentions that they are starting to
port Tk to MS-Windows.  There is a mailing list (see below) for
folk who are interested.

    Someone, whose name I don't have, reported porting Tcl to QNX
with a fair amount of hacking.

    A port of Tcl 7.3, except for glob or commadn pipelines, to OS/2 2.x
using C Set++ has been done by [e-mail] (Bud Bach).  As of this date, I
have no leads on anyone porting Tk to any version of OS/2.

    Also (see "tcl-faq/part4"), the Tcl programs/packages catalog,
for the latest port locations.


D. VMS

    A port of Tcl 7.3 and Tk 3.6 to VMS was done by Angel Li
<[e-mail]>.  The files are at
ftp://mango.rsmas.miami.edu/pub/VMS-tcl/tcl73-tk36-itcl13.tar.Z
and were compressed with the Unix compress command.  The pathname may
be subject to change as I have seen notes from Angel Li mentioning that
BLT 1.6 and the photo widget have also been ported.  These were compiled
on an Alpha running OpenVMS T6.1.

    A port of Tcl 6.3 onto VMS 5.5 was done by Wolfgang Kechel
<[e-mail]> and Till Imanuel Panzschke.  Contact them
directly for assistance.

    A port of most of Tcl 6.7 and Tk 3.2 was done by John Kimball
<[e-mail]> to VMS 5.5.  The files are on:
ftp://src.honeywell.com/pub/tcl67-tk32-on-vms55.tar.Z .

    A port of Tcl 7.0 and Tk 3.3 has being done to VMS on the
VAX and Alpha.  These are available as:
ftp://src.honeywell.com/pub/vms-tcl/tcl70-tk33-on-vms55.tar.Z
or
ftp://src.honeywell.com/pub/tcl70-tk33-on-vms55.tar.Z

    Gerald W. Lester ([e-mail]) says the following _should_ work.
If you installed the POSIX package on VMS (its free), then you should be
able to configure and make tcl.  To access tcl you would have to do one
of the following: 1) Use the POSIX shell, or 2) do a "psx tcl".
Tcl scripts would not execute directly from DCL; to execute a script foo.tcl
from DCL you would have to do "psx foo.tcl".
DISCLAIMER: I have not built any version of tcl under VMS POSIX, these
comments are based on other work I've done with VMS POSIX.

    Also (see "tcl-faq/part4"), the Tcl programs/packages catalog,
for the latest port locations.


E. AmigaDOS

    Karl Lehbauer <[e-mail]> has indicated that
he started a port of Tcl 3.x to the Amiga.  He has a working
version, but is no longer working on it.  His version uses the
Amiga's shared libraries and implements the "send" command.
He wrote a MIDI file loader and player as well.  Contact him for
further details.

    Ty Sarna <[e-mail]> has ported Tcl 6.x to the Amiga.
He says:
> I've ported 3.3 and several 6.x versions to the Amiga, and it can be
> done in under and hour if you leave out the "Unix" functionality.
> However, "Unix" functionality includes things like file I/O!

    Another Amiga user, [e-mail] (Colas Nahaboo), mentioned
that using Amiga gcc and the PD X server DaggeX and Xlibs that a port of
Tk might be possible.

    [e-mail] (Marco van der Heiden) has completed a port
to the Amiga, and suggests Amiga developers contact him by email.

    Also (see "tcl-faq/part4"), the Tcl programs/packages catalog,
for the latest port locations.


F. NeXT

Gianmaria Bertanzon <[e-mail]> reports:
> We are using tk3.2 on NeXT ( Motorola ) under NextStep 3.0 under X.
> The compilation was easy. (we do not remember precisely all the steps)

    Also (see "tcl-faq/part4"), the Tcl programs/packages catalog,
for the latest port locations.


G. Other

    A port to the Apple IIgs and GNO 1.1/GSOS environment is underway.


    A beta port of Tcl 7 has been done to VxWorks.
    You can find it at thor.atd.ucar.edu:~ftp/pub/vx/tclvx7.0.v2.tar.gz .

    Also (see "tcl-faq/part4"), the Tcl programs/packages catalog,
for the latest port locations.


------------------------------

From: FAQ General information
Subject: -IV- Other than C, what languages can talk to tcl/tk?

A. Shell
    There are at least two interfaces which are shell-like.  The
first is wish, which is a windowing shell like interface that is a part
of the Tk package.  The second is tcl, a line command interpreter that
is part of the Extended Tcl package.

B. C++
    Check out tcl++.h in Extended Tcl.  Based on an original
implementation by Parag Patel, it defines a Tcl interpreter class by
which Tcl interpreters can be created as objects under C++.

    Also, ftp://harbor.ecn.purdue.edu/pub/tcl/distrib/tk3.2forC++.patch
is a patch that allows tk 3.2 main.c and other extension routines
to be compiled with a C++ compiler.  Thanks to Ken Yap <[e-mail]>
for this code.

    Mark Diekhans and Karl Lehenbauer have used this, in
combination with the handle facility in Extended Tcl, to build Tcl
commands around C++ classes.

    The Tcl handle facility provides a way to manage table entries
that can be referenced by a textual handle from Tcl code.  This is
provided for applications that need to create data structures in one
command, return a reference (i.e. pointer) to that particular data
structure and then access that data structure in other commands.  An
example application is file handles.

    A handle table was built containing pointers to the instances
of a class that were to be accessed from Tcl, say a class `foo_cl', and
then a "new" command defined that created an instance of that class and
returned a Tcl handle to it.  The handle could then passed among Tcl
commands that accessed each member function.  The handle is in effect
an explicit `this' pointer.

    For example:

     set obj [foo_cl::new]
     foo_cl::baz $obj "Hello world"
     foo_cl::delete $obj

It's not totally object-oriented, but it's still very usable.

C. Modula-3
    Norman Ramsey <elan.uucp!nr> says:
    A long time back, Eric Muller posted a Modula-3 interface to
the C Tcl library.  I wrote down a Modula-3/Tcl interface that used
Modula-3 types rather than C types, and that used objects to build
closures for commands.  I wrote part of the implementation but never
finished it.  I have mailed copies to [e-mail], who asked the
question, and I will post them if there seems to be general interest.

D. Eiffel
    [e-mail] (Stephan Herrmann) says:
    ... [the tclish package provides] the marriage of two very different
principles by means of combining two programming languages into a
hybrid program architecture.

E. Ada
    [e-mail] (Dennis Heimbigner) introduced
an adatcl package which gives Ada programmers access to Tcl interpreters.
See the catalog for details of the package.

F. Other

    Duncan Sinclair <[e-mail]> has details of a hack
into wish.c some hooks for a Tk <-> any language system, and has been using
it for communication with functional languages such as Haskell and Lazy ML.
A paper, plus sample code, is available by ftp from
ftp://ftp.dcs.gla.ac.uk/pub/glasgow-fp/authors/Duncan_Sinclair/fumx.* .

D. Published articles, books, and similarly available resources


1. Computer Shopper, V12 N12, page 862 had an article referencing Tickle,
the shareware package under Macintosh System 7 which is based on Tcl.

2. MacWEEK, Sept 14, 1992, V6 N32, page 91(1), Enhancing text editors for
Mac developers.
This article is a product announcement for Alpha 5.0, the Macintosh
editor which incorporates Tcl.

3. Computer Language, V9 N7, page 76 had an article referencing Tcl in
a hardware/software testing package which talks to a remote machine via
a proprietary interface card.

4. SunWorld, V5 N10, pages 95-96 had a article discussing Tcl, Tk and
expect.

5. UNIX REVIEW, V11 N4, April 1993, pages 93-94, Tcl, Tk, and friends
by Richard Morin.
The article, a part of "The Internet Notebook", mentions a little about
Tcl and Tk, where to find the sources, where to find the draft of the
book, and where to find the contributed software.

6. SunExpert, V4 N3, pages 32-36, by Richard Morin.  As part of Morin's
I/Opener series of articles, this is just a brief overview of Tcl and Tk.
It mentions some of the technical ideas behind Tcl and Tk, where to find
the Tcl source and mentions that the draft of the book is available on
ftp.cs.berkeley.edu.  A 'hello, world' 3 line wish script is really
all that is shown.

7. Libes, Don, "Obfuscated C and Other Mysteries", Wiley & Sons,
January 1993.

This book has a whole chapter on Tcl.  Aimed at the C programmer, it
describes how to effectively use Tcl from C applications.  Another
chapter is on Expect - a walk-through of some of the more interesting
code in Expect.  These chapters originally appeared as separate
articles in The C Users Journal, Vol. 8, No. 7, July 1990, and Vol. 9,
No. 1, 1991.  (Incidentally, the reason the book has such a peculiar
title is that it also contains explanations of the Obfuscated C Code
Contest winners.)

8.  IEEE Design & Test of Computers, June 1993, pages 46-54,
"RISE++: A Symbolic Environment for Scan-Based Testing" by Steve Vinoski.
An article describing a system called the Remote Interactive Scan
Environment (RISE++) that marries Tcl with RPC for the purpose of
testing remote computer systems.

9. The X Journal, March-April 1993, pages 74-81, "HYPERTOOLS
A revolution in GUI applications" (listed in the TOC as "Hypertools: A GUI
revolution") by John K. Ousterhout and Lawrence A. Rowe.

10. Proceedings 1993 Tcl/Tk Workshop, Berkeley, CA, June, 1993.  See above
for online version information concerning these proceedings.

11. iX (multiuser/multitasking magazine), September 1993,
pages 76-84 and 182-185.  Two articles written in the German language.
These concern the design (interpreter and library) of Tcl/Tk and its
connections with C++.  The articles say where to find the packages and
some associated tools (such as XF).  There are short examples on how to
write programs with Tcl/Tk (taken from the demo-directory of the
package) and examples on using XF.  Very informative.

12. Network Computing (CMP Publishing, Inc), November 15, 1993, pp. 99
"Very Rich E-Mail".  References safe-tcl.

13. The Addison-Wesley Publishing Company's quarterly newsletter "Innovations"
dated Winter 93/94 contains an interview with John K. Ousterhout on pp 2,9,10.
It mentions the April 1994 release date, Dr. Ousterhout's background
at UCB and involvement in Sprite.  John gives a overview of what Tk and
Tcl are, what companies are using Tcl, where Tcl/Tk fits in relationship
to AWK, Perl, Motif, and X Windows (sic), mentions there are between 10,000
and 50,000 people developing applications in Tcl/Tk, discusses where in
the classroom the textbook fits, and gives an overview of John's view
of the future of Tcl/Tk.

Also on page 3 of the same newsletter is the overview of the book
listing it as 512 pages and a list price of $36.75.

One can send email to [e-mail] (Pradeepa Siva) to request a copy
of the newsletter, or call him at Addison-Wesley Publishing Company
617/944-3700, ext 2940, or call Addison-Wesley directly to request
it at 800/238-9682.

14. EXE, Nov. 1993, V8 N6, p84(4), Ticklish X windows.
This is a tutorial as a part of a regular Unix column. It covers Tcl/Tk as a
scripting language for writing small X-Windows applications.

15. UNIX Review, March 1994, V12 N3, p87-90.  Tickled Pink, by
Kevin Richard and Eric F. Johnson.  This is part of the programming column
"CROSS THOUGHTS".

The authors attempt to provide a very brief taste for Tcl/Tk and to convey
the purposes for which they consider Tcl suited.  They provide a standard
example of "Hello, world" in Tcl, and also a version written in Motif/C.

There were quite a few surprisingly negative remarks in a column which
tried to be positive about Tcl/Tk.

16. iX, January 1994, pp 148-152, another German article about the
interpretative  class system that is a part of the GOOD graphics system.

17. The first text book dedicated to Tcl and Tk has been published.
The title is _Tcl and the Tk Toolkit_, by John K. Ousterhout.  The
publisher is Addison-Wesley, and it became available in April, 1994.
The ISBN for the book is 0-201-63337-X.  A note from the author about
the book:

"The Tcl book is more up-to-date than the drafts;  for example, the
draft of Part II predates the Tk 3.6 release, so some of the example
scripts don't work with the current Tk release, and the drafts contain
a number of bugs that have been fixed in the final book.  The book
also has more information about the individual widget classes than
the draft, an explanation of Tcl_AppInit, and a number of other
improvements.  Finally, it has an index."

If you cannot find it in your local bookstore, one place you can call
is Addison-Wesley Publishing Company at 800/822-6339.  It is paperback
and the reference price is $36.75.

Note that the examples from the book are available in one large file
as ftp://ftp.cs.berkeley.edu/ucb/tcl/book.examples.Z .

18. Walnut Creek CDROM has published the Tcl/Tk CDROM.  This
is a snapshot of the ftp.cs.berkeley.edu and harbor.ecn.purdue.edu
archives, as well as the archives for comp.lang.tcl newsgroup.
The snapshot of the current CDROM is from early April, 1994.

------------------------------

From: FAQ General information
Subject: -VI- Where do I report problems, bugs, or enhancements - or -
        What is comp.lang.tcl?

    There are two alternatives for reporting bugs and problems.
The first is the USENET news group news:comp.lang.tcl, an unmoderated USENET
newsgroup, created for the discussion of the Tcl programming language
and tools that embed it, such as the Tk toolkit for the X window
system, expect, and Extended Tcl.  Please note that postings of source
code to comp.lang.tcl do not get archived to harbor.ecn.purdue.edu - if
you want your code to be available from the User Contributions archive
you will need to make arrangements for someone to ftp it there.  See
elsewhere in the FAQ for more details on the archive site.

    The second would be to report problems, suggestions, new
ideas, etc. to the author.  Email to

[e-mail] (John Ousterhout)

will get comments to the author of Tcl and Tk - to find the email
address of the authors of other Tcl/Tk based programs,

From: FAQ General information
VII. Are there any mailing lists covering topics related to Tcl/Tk?

    There are quite a number of mailing lists which cover topics
relating to the Tcl community.  As you begin one, if you will send
me information relating to the mailing list, I will add it below.

o    Basic Object Systems (BOS)

    BOS is a SELF-like objects extension to Tcl.

    To join, send email to [e-mail] and then
    send messages to [e-mail] .

o    Dejagnu

    This set of mailing lists are NOT maintained by Cygnus, the
    developers of Dejagnu.

    Dejagnu is an expect 5.x based package designed to be a framework
    for testing other software.  Test suites exist for various GNU
    products such as GDB and binutils.

    3 mailing lists - dejagnu-bugs, dejagnu-developers, and
    dejagnu-questions - have been created as a part of the
    yggdrasil.com listserv.

    To subscribe, send the line:

    subscribe dejagnu-bugs [e-mail]

    to the email address [e-mail] where you put your
    own email address in place of [e-mail] and you put
    the name of the mailing list you wish to join after subscribe.

o    Comp.Lang.Tcl by email

        For those USENET-deprived individuals who are thus unable
    to read comp.lang.tcl, an email alternative is available.
    If you get comp.lang.tcl you do not need to sign up for this list.

        A service called "listserv" is being run out of CERN to forward
    comp.lang.tcl postings via e-mail to people who don't have direct
    access to the newsgroup.  In addition, they are archiving the newsgroup
    so you can retrieve old postings from them.  Here is some more
    information about the service:

    1) send a mail to [e-mail] with one line in the body:

    subscribe tcltk

    2) see how it works (you will receive the mail with instructions from
       listserv);

    3) unsubscribe by a mail to [e-mail] with one line
       in the body:

    signoff tcltk

    4) again, signing off will be confirmed by listserv

o    Macintosh Tcl

        W. Ross Brown <[e-mail]> previously maintained a
    mailing list for discussion of Tcl on the Macintosh.  This list
    is being phased out and users are encouraged to move to the new
    Macintosh Tcl Mailing list.  Here is it's announcement:

    ---

        This Mailing List is devoted to the issues of Tcl on
    the Macintosh.  This includes (but not limited to) such
    topics as ports of Tcl to the Mac (MacTcl), Tcl questions
    relating only to the Mac (file I/O etc.), and porting of Tk to
    the Mac.

        A previous mailing list was supported by Ross Brown.
    Ross, however, had to manage the list by hand.  This list will
    be managed by listserv software and will hopefully be more
    active.  If you were previously on Ross's mailing list you are
    encouraged to switch to this new list.  Ross's mailing will be
    phased out shortly.

        To get more information about the mailing list send a message
    to "[e-mail]" with the line "information mactcl" in
    the body of the message (the subject is ignored).

        To subscribe to the mailing list send a message to
    "[e-mail]" with the line "subscribe mactcl Your Name"
    in the body of the message.  Substitute 'Your Name' with
    whatever your real name is.

        Otherwise, all posting of articles to the mailing list
    should be sent to [e-mail].

o    Microsoft Windows port of Tk

        Simon Kenyon <[e-mail]> announced in early
    April 1994 that the Information Technology Centre of Dublin, IRELAND
    was undertaking the port of Tk to MS-Windows.  He has set up the
    mstk mailing list for those interested in discussing it.

From: FAQ General information
Subject: -VII- Where can I find the FAQ and who do I contact for more
        information about it?

    I am going to attempt to keep a copy of this file up to date on
ftp://harbor.ecn.purdue.edu/pub/tcl/docs/tcl-faq.p0[1-5].gz .  There
are mirrors of harbor.ecn.purdue.edu maintained elsewhere - for
instance, it appears that cs.huji.il, ftp.denet.dk, ftp.luth.se,
hplyot.obspm.fr, rs3.hrz.th-darmstadt.de, sunsite.unc.edu,
swdsrv.edvz.univie.ac.at all have some portion of the harbor archives
available.  Also, I will be posting it on a regular basis to at least
comp.lang.tcl, news.answers, and comp.answers.

    Many FAQs, including this one, are available on the archive
site ftp://rtfm.mit.edu/pub/usenet/news/answers/ .  The subdirectory and
name under which a FAQ is archived appears in the Archive-name line at
the top of the article.  For example, this part of the comp.lang.tcl
FAQ is archived as
ftp://rtfm.mit.edu/pub/usenet/news/answers/tcl-faq/part1.Z .
There is a Northern European archive for the FAQ at
ftp://src.doc.ic.ac.uk/usenet/news.answers/comp.lang.tcl/ .

    There is also a mail server from which you can obtain a copy of
the FAQ.  Send an email message to [e-mail] or
[e-mail]) with the word help in the body of the
message to find out how to use it.

    Also, this FAQ is available from within gopher (by looking at
any one of the gopher holes presenting news.answers or FAQ lists), from
WAIS servers (such as the comp.lang.tcl.src), from a number of sites
which have available via ftp archives of news.answers and comp.answers
(use archie to locate one of these sites available around the world),
and probably other resources as well.

    Other news.answers/FAQ archives (which carry some or all of the FAQs
in the rtfm.mit.edu archive), sorted by country, are:

The user can use a WorldWideWeb client to access the FAQ from this point.

    A WWW URL for the FAQ, where the FAQ is treated simply as one
long scrollable document (suitable for doing a search against, for
instance) is:

http://realsoon.wpi.edu:8080/faqs/tcl.FAQ

    A complete archive of the newsgroup is available from:

ftp://ftp.neosoft.com/pub/archive/usenet/comp/lang/tcl/

A good place to start looking through this archive is:
ftp://ftp.neosoft.com/pub/usenet-archives/comp/lang/tcl/+Index
which contains a list of all the filenames and subject lines of each of the
articles.

    Let me know when you find the FAQ in new and unusual locations
so I can update this resource guide!

    The Tcl commercial use FAQ is available as
ftp://harbor.ecn.purdue.edu/pub/tcl/docs/tcl-commercial-faq.gz
currently.  The author, Gerald W. Lester <[e-mail]>, may in the future
expand the locations where you may find this.  It contains information
either about commercial products which incorporate Tcl as a part of them
or which teach about Tcl and Tk in some manner.
    If you have corrections, enhancements, modifications,
clarifications, suggestions, ideas, new questions, new answers to
questions which have never been asked, or something else that I have
not covered above, contact me at [e-mail].
