## IT MAKES swarm.key as UPLANETNAME
## SAME WISH BE CONNECTED TO THE PRIVATE IPFS MADE FIRST

echo "(✜‿‿✜) Fork UPlanet
This wish makes Player generate or join a private IPFS swarm
It can be use to populate UPlanet ZERO (or not)
All friends with the same wish will share the SECRET
then any can activate a new ipfs daemon connected to that private ZONE
Planet shape could be define from text found in command tiddler
and initiale new euclidian geokeys...
Default :
flaoting points"
