<URL: http://www.equi4.com/pub/dok/ > is a location where sample scripted documents dependant on tclkit are located. These samples demonstrate making documentation available in a single file that would be usable cross platform.
These "doks" rely on Tkhtml, for which builds have been included inside the scripted document. This handles Windows, Linux, and Solaris for now.
If people want Tclkit to run on other platforms - say like MacOS or PalmOS, etc. then they are going to have to give up and actual start working on contributing time, talent, resources, energy, etc. to getting it done.
