This package is intended to replace
.../system/Daemons/vixie-cron.tar.Z, whose binaries use the old stat
call and therefore don't work, and which does not contain any man
pages.

these binaries are the ones fron the sls (which are only available in
a 800k tar package (!) so this is them separatly for the next guy like
me who just needs cron with a minimum of trouble.)

either gunzip the man pages or get perl man.
