NAME
fmt - simple text formatter
SYNOPSIS
fmt [ name ... ]
DESCRIPTION
Fmt is a simple text formatter which reads the concatenation
of input files (or standard input if none are given) and
produces on standard output a version of its input with
lines as close to 72 characters long as possible. The spac-
ing at the beginning of the input lines is preserved in the
output, as are blank lines and interword spacing.
Fmt is meant to format mail messages prior to sending, but
may also be useful for other simple tasks.

BUGS
The program was designed to be simple and fast - for more
complex operations, the standard text processors are likely
to be more appropriate.
