  def caveats
    <<-EOS.undent
      There are three ways to use this program.
      You can either run it from #{HOMEBREW_PREFIX}/lib/#{@@jar_name},
      run "wrf-linker.sh <directory from which you want to run WRFRunner>", or
      cd into the directory from which you want to run the program and run "wrf-linker.sh"
      I highly recommend the third option.
      If you previously ran wrf-linker.sh, you don't need to re-run it.
      If you wish to use this as a library,
      add #{HOMEBREW_PREFIX}/lib/#{@@jar_name} to your classpath.
      The documentation can be found in:
      #{HOMEBREW_PREFIX}/share/doc/#{name}
      run 'open #{HOMEBREW_PREFIX}/share/doc/#{name}/index.html'
      to view it in your default web browser.

      If you are updating from a version less than 4.0.0 to a version of at least 4.0.0,
      check to ensure that none of the Strings in your configuration file start with an '='
      unless they are formulae.  For more details, see:
