Description
ROT13 ("rotate by 13 places", sometimes hyphenated ROT-13) is a simple letter substitution cipher that
replaces a letter with the letter 13 letters after it in the Latin alphabet.
rot13(1) will call out to tr(1) to do this substitution, and will read from standard input unless some
filenames are given.
