xTensor` is a very powerful tool in the hands of an average Mathematica user, but could be difficult for an unexperienced Mathematica user. This is because I have not tried to hide Mathematica subtleties (like delayed assignments, unique symbols or upvalues), but rather I have tried to make as much use as possible of such powerful instruments. If you don't understand those three listed concepts, please spend some (not really much) time with a Mathematica tutorial. It will pay off, even if you finally don't use xTensor`.

If you think you can do your tensor computation by hand in a few lines, then xTensor` is probably too much. This system is designed to be efficient when developing big projects, not small computations: a general-purpose tensor computer algebra system always has hundreds of commands, and only big projects give you enough motivation to learn them.
