Find a replacement for readthedocs
Readthedocs have announced that they will be dropping support for Mercurial repositories and thus, we won't be able to use it in the future.
I really, really hate the "common cold" argument that tries to force everyone to switch to git. There were good reasons for not using it at the start, migration isn't trivial but most importantly: choice is good. It's one of the reasons that many of us chose to use Python in the first place. But I also don't understand the notional work of keeping support for Mercurial: it's really just about keeping a few packages around that someone else maintains.
So, first of all thanks to everyone behind Heptapod that meant we could keep the repo going with a minimum of work. I assume it should be possible to create a documentation website using it and we can use CI to generate the files.
