The first software licence which I had actually read and enjoyed. The days were of DJGPP. I needed to compile C++ and all I had was win98. Every software came with a CPOYING file. Did a edit and began reading. Just so you don’t know what it is, here is the draft you can read. v2 has been here for more than a decade. With new patent and DRM issues coming up in EU, v3 is attempting to include vaccines for those too. you might also like the new concept of copyleft, which is exactly what you think it is - opposite of copyright.
