As we discussed in the last meeting, we reset the ports tree and began from scratch, even though this change involves porting all the packages. Starting small and growing gradually, this approach will reduce build times and consequently lower energy consumption in a world affected by climate change. We will add new ports as users needs arise; ok h3artbl33d@
