(tip 20)\n\
-> Using field connections to describe dependency graphs.\n\
(tips 21 to 26)\n\n\
This shall be it as a first glimpse on \033[92mguacamole\033[0m.\n\
I put all the code of this little tutorial in a seperate example \n\
directory called 'tutorial_result'. Copy this directory and start \n\
writing your own, spicy \033[92mguacamole\033[0m application! \n\n\
Of course, there are alot of other things to\n\
learn and to experiment with!\n\n\
Anyhow, thank you for taking this little course\n\
and have fun fooling around with \033[92mguacamole\033[0m!\n",
