The implementation of cron is really stupid! They could have allowed
both day of week and day of month with two lines and then anded the day
of week/month fields to do what you want.

However, you can get what you want at low cost by running a script every
Tuesday and checking the date, as:
	set `date`
	if test $3 -lt 8 -o $3 -gt 14; then exit 0; fi
	# Now do what you really wanted

Thanks for pointing this out, I always assumed that the crontab worked
in the logical way.
