We've released today the Runtime Converter 2.0. Among its main improvements are namespaces support, spring boot, gradle, and maven intergration, and speed improvements. To load up a project, there is no longer any need to download anything. Just type "gradle bootRun" and it will download the runtime libraries + depenencies and compile your project.
Additional features are pass-by-reference functions, "variable variables" in the top-level scope, shell exec "backticks" support, namespace import rules support, and basic references support including foreach with "&".
There is also a general stability upgrade, where conversions will no longer fail on errors, but continue attempting to provide as much converted code as possible.
