 * This should be a drop-in replacement for qmail's checkpassword.

 * We don't (yet?) set uid or environment. Test like:
 * {echo -n name; unicode -t 0000;
 * echo -n secret; unicode -t 0000;
 * echo -n `{date -n}} |[3=1] 8.out /bin/echo foo
 * Very lightly test only. Not robust in the face of misuse.
