i plan to commit newsyslog from NetBSD which does all the rotation
automatically - you may configure it using /etc/newsyslog.conf

you may get my test-package from freefall

  ~graichen/misc/review.tgz

or via ftp from

  dirac.physik.fu-berlin.de:/pub/freebsd/misc/review.tgz

please look at it and send me all problems you find with it - i asked
around in hackers if there are any contra's to committing it - but i
got only pro's :-)

i plan to commit it between christmas and new year - if anybody will
test it before
