wtk is a proof of concept implementation from [http://www.markroseman.com/%|%Mark Roseman%|%] for providing GUI functionality for Tcl using a mechanism, which I ([apw]) see similar to rpc (remote procedure call). That does not exclude the use of that package for running in the browser without any remote call. The git repository with the sources can be found here: [https://github.com/roseman/wtk%|%wtk repository%|%] Please correct me, if I am wrong with that statement. <>package
