  def caveats; <<-EOS.undent
    To install symlinks for compilers that will automatically use
    ccache, prepend this directory to your PATH:
      #{opt_libexec}

    If this is an upgrade and you have previously added the symlinks to
    your PATH, you may need to modify it to the path specified above so
    it points to the current version.

    NOTE: ccache can prevent some software from compiling.
    ALSO NOTE: The brew command, by design, will never use ccache.
