NAME
crc - checksum files
SYNOPSIS
crc
file ...
DESCRIPTION
For each file,
crc
calculates and prints a 32-bit CRC,
the byte count, and the file name.
It is typically used to validate files transferred between
different systems, and is useful in detecting subtle disk corruption.
Crc
uses a checksum compatible with the
DOS
version of crc,
as well as the "crc" command in ZCOMM and Professional-YAM
(high reliability communications programs).
The 32-bit CRC used is the frame
check sequence in ADCCP (ANSI X3.66, also known as FIPS PUB 71
and FED-STD-1003, the U.S. versions of CCITT's X.25 link-level
protocol).

BUGS
Although most unlikely,
files with different data may still produce the same crc value.
