this is a copy of the nut-nutrition meal planning and nutrition data software from ubuntu 14.04 back when it was still good.
i can't get newer versions of nut to work at all, and they probably don't work the same.
you should be able to run this on a linux system by copying this directory to /usr/share and put nut-nutrition on your PATH.
then just type `nut-nutrition` and it should show a crusty old TUI menu interface, which you'll learn to love, eventually.
