What does "GNU's not Unux" stand for?
This has puzzled me ever since I first heard it. The standard definition of GNU is, an acronym for "GNU is not Unix". Is it just me, or is that not an answer? What is GNU? Does that refer to the animal gnu? If so why are all the letters capitalized in the definition as though it were itself an acronym for something? What do gnus have to do with computer software anyway?! And why did they want the acronym be "GNU is not Unix"?
Can anyone enlighten me on this? Thanks a lot.
