SRC_REV="6"  # revision used by upstream

# HINTS:
# -> non-free modules are x86 and amd64 only
# -> iscan frontend needs non-free modules
# -> sane-epkowa should be usable on every arch
# -> ${P}-${SRC_REV}.tar.gz    (for gcc 3.2/3.3)
# -> ${P}-${SRC_REV}.c2.tar.gz (for gcc 3.4 or later)

# FIXME:
# Make jpeg/png optional. The problem is, that the configure script ignores --disable-*,
# if the corresponding lib is found on the system.
# Furthermore, iscan doesn't compile w/o libusb, this should be fixed somehow.

# feel free to add your arch, every non-x86
# arch doesn't install any x86-only stuff.
