.TH ROT 1

.SH NAME

rot \(en caesar-rotate text

.SH SYNOPSIS

rot
.RB ( rotation )

.SH DESCRIPTION

Rot writes to standard output each character from standard input, rotated
around the Alphabet the given number of times.
.PP
If the rotation is unspecified, the default is 13 places, functionally
equivalent to rot13(1).

.SH DECRYPTION

A character rotated 26 places around the Alphabet is the same as the initial
character, so to decrypt rotated text, rotate the text an additional amount of
places so as to make the summed rotation equal to 26 places.

.SH DIAGNOSTICS

Rot will exit with the appropriate status from sysexits(3).
