This mod is inspired by older Minetest "sky" mods, but is sufficiently
different that it should be viewed as a new mod.

It implements a transition from normal sky to  outer space in a manner
that is compatible with other mods in the Bucket World "_game" and de-
rived "_games".

For example,  the Bucket World versions of  "asteroids" and  "weather"
depend on this mod.
