Erlang R18.0 Docs
Language sites get knocked offline from time to time, so in addition to the Guile 2. manual I also keep a mirror of the Erlang R18 docs. I’ve never needed to link to them from here, but today has been a rough day around the internet for some reason so here we are. Depending on how long they stay down I might add the latest revision as well.
