# -> non-free modules are x86 only
# -> isane 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, isane doesn't compile w/o libusb,
# this should be fixed somehow.

# available x86 plugins (will be assembled below)
