The information that used to be here was way out of date (anno 2002).
There now exists a tcl only version of tclkit on Windows called tclkitsh. The stdout problem mentioned below doesn't exist for tclkitsh. In addition, scripted documents such as wikit are now based on VFS and don't support the command-line introspection options of pre-VFS designs. Instead the SDX scripted document should be used to list and extract the scripts from wikit.
