— Mac specific changes for Mac Tcl/Tk 8.3.4, Oct 19, 2001 —

– timezone support

– mac time epoch changed to standard unix epoch

– glob -dir compatibility mode for unix style relative paths

– fix to glob -join, it wasn’t traversing aliased folders. This notably
fixes the bug of pkgIndex files not being seen inside aliased folders.

– when loading shared libraries, comparison of package name to code
fragment name changed to only match on the length of the package name,
this allows for fragment names with version numbers appended.

– crashing bug fix when printing to console at program exit after
the console has already been closed.

– correct use of Tcl_JoinPath in tk_library initialization

– reorganized resources to avoid multiple copies in applications and
shared libraries, the script libraries & Xcursors etc are now no longer
duplicated in Wish but are only included in the resources of Tk.shlb.
Corrected how tk deals with tcl library files present both in
resources and in $tk_library directory (the $tk_library now always
takes precedence).


— 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

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.
