- * md5sum.c - Generate/check MD5 Message Digests
- *
- * Compile and link with md5.c. If you don't have getopt() in your library
- * also include getopt.c. For MSDOS you can also link with the wildcard
- * initialization function (wildargs.obj for Turbo C and setargv.obj for MSC)
- * so that you can use wildcards on the commandline.
- *
- * Written March 1993 by Branko Lankester
- * Modified June 1993 by Colin Plumb for altered md5.c.
