> The syntax has changed - instead of --kpts=8,8,8 --h=0.18 --fit, try using -k 8,8,8 -g 0.18 -O. I'm not sure if that'll do everything, but it should help somewhat. The help for that command is "gpaw -h".

Actually, "-k 8,8,8 -g 0.18 -O" works for GPAW version 0.6, but the
tutorial uses the new syntax from the latest development version of
GPAW.  Yes, it's a bit of a mess!
