Just as a note for the future: mefeels that it'd be great (for clarity as well as simplicity) if cron(8) would be merged into at(1) at some point:
% echo make-coffee | at teatime every day (Or similar.) Such a change would allow each job to be individually manipulated, as well. --zeurkous. P.S.: No patch for UNIX, at least from me: you folks'll have to do w/ me advice :) -- Friggin' Machines!
