There are two kinds of mappings, one where the pcic does all the work and one where the card does the work. The latter kind should be used for leveling driveways with, but that is nontheless the reason for 80% of the CIS complexity. -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
