        To install the --HEAD version of mercurial, you have to:
          1. `brew install mercurial`  # so brew can use this to fetch sources!
          2. `brew unlink mercurial`
          3. `brew install mercurial --HEAD`
          4. `brew cleanup mercurial`  # to remove the older non-HEAD version
