Tcl/Tk

Tcl (Tool Command Language) is an embedded scripting language by John Ousterhout. The Tcl interpreter is a library which can be linked into other programs to provide a way of extending their functionality (for example, a text editor which includes Tcl could allow users to add new editor commands as Tcl scripts). There is also a shell (tclsh) which lets you execute Tcl code directly.

Tk is a Tcl toolkit for developing windowed applications, and it has now been ported from Unix to Windows. There is also a shell (wish) which executes Tk scripts, so you can write Windows programs as Tk scripts. Tk can also be used with other languages, notably Ada 95 and Perl.

	Active State A company which is now the main source of binary distributions of Perl, Python and Tcl/Tk for Windows. Unfortunately, their licenses do not permit their products to be redistributed by third parties. However, the source code for all these products is free, so other binary versions are available elsewhere if the Active State license restrictions prove to be a problem, or you can compile the source code yourself.
