Some clever clogs made a snazzy tool called SciLab as another not-MatLab.1 Flex Dock is the framework that (I think) they developed for docking frames. It’s not in Maven Central so I’ve forked it and deployed it to my own repository. convert the build The actual conversion was embarrassingly easy since the gradle importer stuff really works for this sort of thing. As a matter of personal preference, I re-arranged the build scripts to be a single file but otherwise left them as-is.
