I see this software development stalled and sad, as if they didn't have more contributors to the larger community (though many people still use it).CraftbeerpiThen I stumbled across a Python-written craftbeerpi, which has an active contributor-supported development community. The original author (and current maintainer), Manuel Fritsch, has done a good job of contributing and handling feedback issues. It took me a little time to
