eltclsh (editline tcl shell) is an interactive shell for the TCL programming
language. It provides command line editing, history browsing as well as
variables and command completion thanks to editline features. The completion
engine is programmable in a way similar to tcsh, and comes with an intelligent
completion for the full tcl language by default.

The package also provides elwish, an interactive interpreter for the Tk
toolkit.

eltclsh is an open-source software released under a BSD license.
