NR is a point and click GUI interface for browsing Usenet news. The NR interface is built using the Tk interface toolkit, and coded entirely in the Tcl scripting language. NR was designed as a framework for pursuing research into electronic information browsing. As a result, NR had strong requirements for configurability, extensibility, portability, and performance. This paper describes how those requirements were met through the use of features and extensions of the Tcl/Tk scripting language. The paper also describes some of the information filtering technologies implemented in NR.
