def caveats
if build.head? then <<-EOS.undent
Mercurial is required to fetch its own repository, so there are now two
installations of mercurial on this machine. If the previous installation
was done via Homebrew, the old version may need to be cleaned up and new
version linked:
brew cleanup mercurial && brew link mercurial
