      Users must agree to a license before downloading SRILM, so this formula
      does not do so automatically.  Please fill out the download form on the
      SRILM home page and move the downloaded archive to the following path:

        #{HOMEBREW_CACHE}/srilm-1.7.1.tgz

      Then run `brew install srilm` as usual.
