[incr Tcl] (or itcl) is a popular object-oriented extension for the embeddable Tcl scripting language. The name is a play on C++, and itcl has a similar object model, including multiple inheritance and public and private classes and variables. Unlike most OOP extensions to Tcl, itcl is written in C for speed.

This package contains everything you need to run itcl scripts and itcl-enabled apps.
