[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.
