— Mac specific changes/fixes for Mac Tcl/Tk 8.3.3, May 4, 2001 —
* The following are the main mac specific changes since 8.3.2p1:
– use of DLLIMPORT and DLLEXPORT like on other platforms, no longer use
.exp files to determine what gets exported from DLLs, this also needs
the #defines BUILD_tcl, BUILD_tk & STATIC_BUILD to be setup properly,
thus
– revised precompiled header handling: we now include a common header
file ‘MW_TclHeaderCommon.h’ from all .pch files, the .pch files
themselves now only setup #defines like in makefiles on other
platforms.
– added support for -filetypes option to tk_getSaveFile (tcl bug #221636)
– added update event handling for background windows while in a
NavigationMgr dialog
– fixed crashing bug and memory leak in memory allocation code; modernized
memory allocation, now use temporary memory instead of system heap
when application heap is full and use RecoverHandle instead of memory
allocation tracking; increased fraction of application heap reserved
for OS routines to 512K.

— About Tcl/Tk —
Tool Command Language (Tcl) is an interpreted language and a very portable
interpreter for that language. Tcl is embeddable and extensible, and has
been used by companies and organizations world-wide since its creation in
1988 by John Ousterhout.
As a language, it is much like UNIX shell languages. There is very little
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. These building
blocks appear as commands, or verbs, in the script language. It is easy to
embed Tcl into a legacy program so you can script the behavior of that
program and add in other building blocks like a GUI interface. The 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 creation
of graphical interfaces that run on Mac, Windows, UNIX and other platforms.

An informal survey shows over 100 Tcl-related SourceForge projects
