For each file, _c_r_c 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. _C_r_c uses a
checksum compatible with the DOS version of crc, the 32 bit
CRC used by PKZIP version 0.9, 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).

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