Aug 6, 2003

I’m pleased to announce the availability of Mac OS X binary
distributions for Tcl/Tk Aqua 8.4.4, the Mac OS X native port of the Tcl
scripting language and the Tk toolkit.

The distributions are downloadable as compressed disk images from the
Tcl/Tk Aqua file release page on Sourceforge:

Three variants are available:

* TclTkAquaBI: Batteries-Included distribution, includes many popular
extensions (c.f. list below). This is a superset of ActiveState’s
ActiveTcl distribution (on other platforms).
Installs in systemwide locations, administrator password required. (15.3M)

* TclTkAqua: smaller distribution of just the TclTk frameworks, Wish,
tclsh and html docs (including debug versions of the frameworks).
Installs in systemwide locations, administrator password required. (4.8M)

* TclTkAquaStandalone: drag & drop install capable, self-contained
version of Wish with embedded TclTk frameworks (no debug frameworks
or documentation included). Can be used off read-only media and
installed by unprivileged users. (1.7M)

Note that these distributions require at least Mac OS X 10.2 (Jaguar);
Mac OS X 10.1 is no longer supported.

— About Tcl/Tk —

Tool Command Language (Tcl) is an interpreted language and a very
interpreter for that language. Tcl is embeddable and extensible, and
been used by companies and organizations world-wide since its creation
1988 by John Ousterhout.

As a language, it is much like UNIX shell languages. There is very
syntax and it is easy to learn. It is used to glue together building
blocks built in system programming languages like C, C++, and Java.
building blocks appear as commands, or verbs, in the script language.
is easy to embed Tcl into a legacy program so you can script the
of that program and add in other building blocks like a GUI interface.
Tcl interpreter is written in C and has been ported to almost every
computer platform.

Tk is a portable GUI toolkit for Tcl, it allows simple and dynamic
of graphical interfaces that run on Mac, Windows, UNIX and other

The following were the main changes in Tcl/Tk 8.4.4. A complete list
