Tcl [SEP] History
The Tcl programming language was created in the spring of 1988 by John Ousterhout while working at the University of California, Berkeley. Originally "born out of frustration", according to the author, with programmers devising their own languages intended to be embedded into applications, Tcl gained acceptance on its own. Ousterhout was awarded the ACM Software System Award in 1997 for Tcl/Tk. The name originally comes from Tool Command Language, but is conventionally spelled "Tcl" rather than "TCL". Tcl conferences and workshops are held in both the United States and Europe.
