Well, yeah. Hey chaps, Journal entry-time: Feel free to use any of my vectors ... yada yada yada ... give credit, where credit is due ... et cetera et cetera, you know the drill.
Unfortunately and despite my best efforts(double and triple checking every vector), some errors will always manage to sneak in. Don't hesitate to point them out to me, so I can fix 'em pesky little rascals.
So long, cheers.
