# Repackage the official UltimaIV.zip from http://www.ultimaforever.com/
# so that its zip file structure is the more-or-less the same as the dragon
# release listed in the .info file. Also the official release includes the
# PDF docs, so we pack them into ultima4_scanned_docs.zip like the build
# script expects.

# The resulting package will be missing Keyboard.txt. Since the contents
# of Keyboard.txt are in the man page, I don't see it as a problem. The
# package will also have an extra copy of the map (Map.jpg), higher res
# than Map.bmp, but scanned from a creased map.

# so the SlackBuild script will be smart enough to handle the
# case where it's missing.
