ClassyTcl is a dynamically loadable object system for Tcl. Both a Tcl-only and a C implementation are available. It also doesn't require patches to the Tcl core, which makes installation and maintenence easier. Performance is quite adequate. The C version is gives extra speed, and makes it possible to implement some methods in C. In contrast to other object systems for Tcl, it is not modeled after the object system designed for a completely different language, such as C. The system is simple but flexible. Classes and objects are dynamic, and can easily be queried, changed, and debugged at runtime.
Clig uses a simple description file to create C-code to interprete the typical *NIX command line as well as an up-to-date usage-message and a manual page skeleton. It supports Flag, String, Int, Long, Float and Double types, with ranges, defaults, and more. The generated C-Code is ANSI but has been reported to work with C++. It is self contained code which does not depend on any library other than libc. Included is a TCL-only TCL-package to instrument your TCL scripts the same way as your C-programs.
