Description:
Extended Object Tcl (XOTcl): Object orientation for Tcl - shared library
Extended Object Tcl (for short: XOTcl, pronounced exotickle) is an object-oriented scripting language based on Tcl. It was originally designed for providing language support for design patterns and provides novel constructs such as filters or transitive mixin classes. The language is designed for empowering rather than constraining system developers. The basic object model is highly influenced by CLOS.
