## SYNOPSIS

         sum file

## OPTIONS

         (none)

## EXAMPLES

         sum /user/ast/xyz   # Checksum /user/ast/xyz

## DESCRIPTION

         Sum computes the checksum of one or more files.  It is most often used to
         see  if  a  file copied from another machine has been correctly received.
         This program  works  best  when  both  machines  use  the  same  checksum
         algorithm.  See also crc.
