# Tk

Tk is a -like widget set that gives access to the widgets via Tcl commands. The widget classes use Tcl to implement parts of their own functionality, and to implement application specific functionality. This allows it to create complex user interfaces in an interpreted scripting language. The performance of the resulting code is excellent, and the use of the commands is simple.
