More detailed description:
It makes coordinates relative to some center
rotates around of it, if you write degrees for angles more than 0 in program
and then shifts the location of those objects to some position elsewhere
after that, it creates new file b.txt where the changed file is written
or you can rewrite the existing one.
P.S. so basically this program fastly changes "pos = ..." and "rotate = ...." strings in a file.
some people who change things in solar systems, perhaps need it to move multiple stuff around.
P.P.S. I didn't test it. so not exactly sure if it rotates properly. Yeah I tried to rotate but, not sure if it would correspond well with "rotate = " game parameter.
