"HCL Configuration Language" will feel redundant to anyone who thinks
they know what "HCL" is supposed to stand for, even though our docs don't
actually expand the abbreviation at all. This new version is also still
redundant with that interpretation, but at least it emphasizes that it's
a toolkit for creating configuration languages rather than a configuration
language in its own right.
Git isn't available in the Read The Docs build, but we don't actually need
it there anyway because we are told the version number that Read The Docs
thinks it is building.
