rediff is a diff format converter (from unified to context or vice versa). This script takes a context or unified diff as input and produces a diff that would be created by diff program if it was run with the command-line options passed to this script. The -c, -u, -b, -w, -t options are supported. The "non-diff" (-r) option can be used to reverse the diff.
