It seems worthwhile mentioning that DbC's primary purpose
is not to augment programs with run-time checks; rather, DbC asks
for programmers who write as if there was no assertion monitoring
but who explain their code with pre/post/inv.  The operator may
turn on run-time monitoring so that he/she is notified if something goes
wrong (disproving the programmers' assumptions; the monitor stops
the program or runs the remains in a debugger).
