#
# This port builds version 2.11.0 of the sane-epkowa driver for SANE.
# (more recent versions do not work - read details below).
#
# The source for sane-epkowa is accessible through
#
#	 http://www.avasys.jp/lx-bin2/linux_e/spc/DL1.do#download
#
# Note that the download interface above requests to fill a form,
# and returns only the most recent version of the software.
# However the license of the software is GPL-like, and the documentation
# coming with the code (README, non-free/AVASYSPL.en.txt) explicitly
# mentions that source redistribution is allowed with no other conditions.
#
# Given that there is no other way for us to get version 2.11.0,
# and since this is allowed by the license, we go straight at the
# URL for the .tar.gz we need.
# The various versions of the code are at:
#
# http://lx1.avasys.jp/iscan/2.7.0/iscan-2.7.0-1.c2.tar.gz
# http://lx1.avasys.jp/iscan/2.8.0/iscan-2.8.0-1.c2.tar.gz
# -- unknown URL for version 2.9.0
# http://lx1.avasys.jp/iscan/2.10.0/iscan_2.10.0-1.tar.gz
# http://lx1.avasys.jp/iscan/2.11.0/iscan_2.11.0-1.tar.gz
# http://lx1.avasys.jp/iscan/2.12.0/iscan_2.12.0-4.tar.gz
# --- version 2.13 never released
# http://lx1.avasys.jp/iscan/2.14.0/iscan_2.14.0-3.tar.gz
# http://linux.avasys.jp/drivers/iscan/2.15.0/iscan_2.15.0-3.tar.gz
#
# Version 2.7.0 to 2.11.0 build on FreeBSD without any patch.
# This port builds version 2.11.0, which is enough to detect the new
# multifunction SX400 scanner/printer that is not supported by the 'epson'
# backend coming with sane-backends.
#
# Version 2.15.0 builds with the patches included with this port,
# but does not work at runtime due to various issues not solved yet.
