The intention is to keep to repo root clean while the list of packages is slowly growing. Additionally, a bunch of small (~30 LoC) files in the repo root is merged into a single maddy.go file, for the same reason. Most of the internal code is moved into the internal/ directory. Go toolchain will make it impossible to import these packages from external applications. Some packages are renamed and moved into the pkg/ directory in the root. According to https://github.com/golang-standards/project-layout this is the de-facto standard to place "library code that's ok to use by external applications" in. To clearly define the purpose of top-level directories, README.md files are added to each.
