python-fchksum is a module used to find checksums
of files (or stdin). It supports md5, crc32,
cksum, bsd-style sum, and sysv-style sum. The
advantage of using fchksum over the Python md5 and
zlib(.crc32) modules is both ease of use and
speed. You only need to tell it the filename, and
the work is done by C code.
