itcl3-dev - 3.4.3-3.1 main

[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 the headers and libraries needed to embed or
add C extensions to itcl.
