  def test
    puts <<-EOS.undent
      To test CouchDB, start `couchdb` in a terminal and then:
        curl http://127.0.0.1:5984/

      The reply should look like:
        {"couchdb":"Welcome","version":"1.1.0"}
    EOS
  end

    If this is your first install, automatically load on login with:
        mkdir -p ~/Library/LaunchAgents
        cp #{prefix}/Library/LaunchDaemons/org.apache.couchdb.plist ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/org.apache.couchdb.plist

    If this is an upgrade and you already have the org.apache.couchdb.plist loaded:
        launchctl unload -w ~/Library/LaunchAgents/org.apache.couchdb.plist
        cp #{prefix}/Library/LaunchDaemons/org.apache.couchdb.plist ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/org.apache.couchdb.plist

    Or start manually with:
        couchdb
    EOS
  end
