I just tried to get started with tclkit to try it out. The first result for "getting started tclkit" has links with 404. I was able to download a prebuilt binary for macOS which does run, but I can't find any clear tutorials for how to start building apps (the top result for "getting started" is from 2008). I decided to try some example apps instead, so downloaded some .kit files and tried to run them: % ./tclkit-8.6.3-macosx10.5-ix86+x86_64 fractal.kit 2019-06-25 12:14:12.541 tclkit-8.6.3-macosx10.5-ix86+x86_64[18970:1942703] -[TKWindow setCanCycle:]: unrecognized selector sent to instance 0x10023a910 2019-06-25 12:14:12.542 tclkit-8.6.3-macosx10.5-ix86+x86_64[18970:1942703] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[TKWindow setCanCycle:]: unrecognized selector sent to instance 0x10023a910' It crashes. Hard to compare with the ecosystem and maturity of the web.
