22 The code segment between "#ifdef CRCTAB" and "#else" is the code-
23 which calculates the "crctab". It is included for those who want-
24 verify the correctness of the "crctab". To recreate the "crctab",-
25 do something like the following:-
26-
27 cc -DCRCTAB -o crctab cksum.c-
28 crctab > crctab.h-

30 This software is compatible with neither the System V nor the BSD-
31 'sum' program. It is supposed to conform to POSIX, except perhaps-
32 for foreign language support. Any inconsistency with the standard-
33 (other than foreign language support) is a bug. */-
