    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

    Alternatively, automatically run on startup as a daemon with:
        sudo launchctl list org.apache.couchdb \>/dev/null 2\>\&1 \&\& \\
          sudo launchctl unload -w /Library/LaunchDaemons/org.apache.couchdb.plist
        sudo cp #{prefix}/Library/LaunchDaemons/org.apache.couchdb.plist /Library/LaunchDaemons/
        sudo launchctl load -w /Library/LaunchDaemons/org.apache.couchdb.plist

    Or start manually as the current user with `couchdb`.

    To test CouchDB, start `couchdb` in a terminal and then:
      curl http://127.0.0.1:5984/

    The reply should look like:
      {"couchdb":"Welcome","uuid":"....","version":"1.3.0",
          "vendor":{"version":"1.3.0-1","name":"Homebrew"}}
    EOS
  end
