33 | * Revision 1.5 2000/12/06 20:33:27 mdw |
34 | * Make flags be macros rather than enumerations, to ensure that they're |
35 | * unsigned. |

12902a5c |
40 | * Revision 1.3 2000/07/29 17:02:43 mdw |
41 | * (checkhash): Be pettier about spaces between the hash and filename, for |
42 | * compatiblity with `md5sum'. |
43 | * |
5af0f9cb |
44 | * Revision 1.2 2000/07/15 21:14:05 mdw |
45 | * Missed `-e' out of the usage string. |
46 | * |
e375fe33 |
47 | * Revision 1.1 2000/07/15 20:52:34 mdw |
48 | * Useful replacement for `md5sum' with support for many different hash |
49 | * functions and for reading filename lists from `find'. |
