  def caveats; <<-EOS
The JackRouter CoreAudio device is located in jack/0.87/Audio/Plug-Ins/HAL/JackRouter.plugin
within the Homebrew Cellar. Link this into /Library/Audio to install (requires restart.)

ie: sudo ln -s #{HOMEBREW_PREFIX}/Cellar/jack/0.87/Audio/Plug-Ins/HAL/JackRouter.plugin /Library/Audio/Plug-Ins/HAL/
(you make need to make the parent directories first.)

Also included within the Audio subfolder are an AudioUnit and VST plugin.
