-/*----- Revision history --------------------------------------------------* 
- *
- * $Log: hashsum.c,v $
- * 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'.
