Looks like [the pyyaml package](https://github.com/yaml/pyyaml) (as well as their entire Github org?) has disappeared entirely from Github. The packages are still up on PyPI, but as dotbot uses it as a submodule, my current dotfiles workflow is broken as it's not able to read the config file. At this point I don't know if this is a temporary issue or not, but I'm probably the only one affected.
