+Hi, it's been 7 years since I last looked at this, and I'm surprised to find
+that I'd got it up to a merge-request state; I've dusted it off and done some
+clean up and testing, but it's working (albeit not via websetup). I've revamped
+the docs and rebased the branch. Can someone please consider merging ([[joey]]
+or [[smcv]]?) or otherwise feed back on this? Thanks! — [[Jon]] (2018-09-25)
