-/*----- Revision history --------------------------------------------------* 
- *
- * $Log: hashsum.c,v $
- * Revision 1.7  2001/02/21 20:03:22  mdw
- * Added support for MD2 hash function.
- *
- * Revision 1.6  2001/01/25 21:40:14  mdw
- * Support for new SHA variants added.
- *
- * Revision 1.5  2000/12/06 20:33:27  mdw
- * Make flags be macros rather than enumerations, to ensure that they're
- * unsigned.
- *
- * Revision 1.4  2000/08/04 23:23:44  mdw
- * Various <ctype.h> fixes.
- *
- * Revision 1.3  2000/07/29 17:02:43  mdw
- * (checkhash): Be pettier about spaces between the hash and filename, for
- * compatiblity with `md5sum'.
- *
- * Revision 1.2  2000/07/15 21:14:05  mdw
- * Missed `-e' out of the usage string.
- *
- * Revision 1.1  2000/07/15 20:52:34  mdw
- * Useful replacement for `md5sum' with support for many different hash
- * functions and for reading filename lists from `find'.
