As is well known, most [Tcl] distributions provide two interpreters,
[tclsh] and [wish].  The main differences between these are that wish
automatically starts Tk and on Windows doesn't pop up a DOS console
window ([puts] commands to standard output just don't go anywhere).
Until recently, for technical reasons using wish had to be the only way
to get at Tk.  However, in later versions by [using Tk as a loadable
package] you can use it via tclsh and still have full console access on
all platforms.

----
Many other languages have Tk packages; some of which work by loading all of Tcl in
and then executing Tk commands.
[Perl/Tk], on the other hand, rewrote all of Tk in a way that wasn't bound to Tcl, for example.
See [Tcl and other languages].

Among other topics in "Tcl/Tk for Rapid Web Services Development"
[http://cedar.intel.com/cgi-bin/ids.dll/content/content.jsp?cntKey=Generic%20Editorial%3a%3aws_tcl&cntType=IDS_EDITORIAL],
[CL] hints at the advantages Tk interfaces enjoy over both
Web applications and traditional Visual Basic form-oriented
GUIs.  He's published dozens of other articles
[http://phaseit.net/claird/comp.lang.tcl/tk.html]
on various aspects of Tk (without more than scratching the
surface of all that can be written).
For instance, see http://www.itworld.com/AppDev/1243/UIR000804tk/ as
a nice intro to Tk.

Look here to find tutorials for Tk in Tcl [http://www.geocities.com/binnyva/code/tcl/tutorial/tk.html]
and in Perl [http://www.geocities.com/binnyva/code/perl/perl_tk_tutorial/].

[TV] Where does the name come from, ToolKit?

Yes.
----

Tk has an [X]lib Emulation Layer [XLEL], which is one part in making Tk work across different platforms.

That there is such a level is an important reason why
[Tk generation when X11 headers are missing]
can be an issue: the Tk source uses X11 headers even when Tk at runtime uses some other windowing system.

[[Things to explain:  Bryan Schofield's posting on multiple Tk interpreters;
double-buffering examples; ...]]

----
Has anyone been thinking adding a tutorial for Tk into the Tk source code
distribution, similar in concept to the Tcl tutorial being added in Tcl 8.5?

[DKF]: Thinking? Yes. Doing anything about it? No. A set of lessons for Tk would be a ''very'' welcome addition!
