    You can enable memcached to automatically load on login with:
        mkdir -p ~/Library/LaunchAgents
        cp #{prefix}/com.danga.memcached.plist ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/com.danga.memcached.plist

        Or start it manually:
            #{HOMEBREW_PREFIX}/bin/memcached

        Add "-d" to start it as a daemon.
