       rot13 — shortcut to tr(1) for ROT13


       rot13 [file...]


       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.
