DESCRIPTION="Canon printer drivers for models i250, i255, pixus560i, pixus860i and pixus990i"
# The drivers for i250/i255 can be found at the website of Canon New Zealand
#  http://www.canon.co.nz/products/printers/colour_bj_printers/i250_drivers.html
# The drivers for 560i/860i/990i can be found at the website of Canon Japan
#  http://www.canon-sales.co.jp/drv-upd/bj/bjlinux240.html
HOMEPAGE="http://www.canon.co.nz http://canon.jp/"

# These are a lot of packages... we also fetch version ${MY_OLD_PV} from New Zealand

# bjcupsmon-2.4-0 provides a generic interface, so we just need the latest
# version.

# I know, that precompiled RPMs are evil, but we just need some libs...

# bjfilteri255-2.3-0.i386.rpm comes from a strange source... does anybody know
# the official one?? Couldn't find it anywhere

# The patch belonging to this ebuild was moved to the gentoo mirrors because of
# it's size (~170KB at $PV 2.4.0-r1)
