Tcl (originally from "Tool Command Language", but conventionally rendered as "Tcl" rather than "TCL"; pronounced as "tickle" or "tee-see-ell") is a scripting language created by John Ousterhout. Originally "born out of frustration," according to the author, with programmers devising their own (poor quality) languages intended to be embedded into applications, Tcl gained acceptance on its own. It is commonly used for rapid prototyping, scripted applications, GUIs and testing. Tcl is used on embedded systems platforms, both in its full form and in several other small-footprinted versions. Tcl is also used for CGI scripting and as the scripting language for the Eggdrop bot. Tcl is popularly used today in many automated test harnesses, both for software and hardware, and has a loyal following in the Network Testing and SQA communities.

The combination of Tcl and the Tk GUI toolkit is referred to as Tcl/Tk which is often pronounced "tickle tock."
