+Over the years many similar tools have died out, the only actively maintained
+alternative is mnauw's fork of this project:
+https://github.com/mnauw/git-remote-hg[mnauw/git-remote-hg]. I've merged some of
+his patches, and he has merged some of my patches, so the projects are mostly in
+sync, but not quite. In particular Nauwelaerts' fork has many administrative
+extensions, which although useful to some people, I don't believe they belong
+in the core.

+mnauw's note; I do not know what "the core" means?
+However, the "extensions" provide useful and possibly
+critical maintenance wrt git-remote-hg's internal data, so it belongs as close
