# http://miniupnp.free.fr/ or http://miniupnp.tuxfamily.org/
# Author : Thomas Bernard
# for use with GNU Make
#
# options can be passed to genconfig.sh through CONFIG_OPTIONS :
# $ CONFIG_OPTIONS="--ipv6 --igd2" make -f Makefile.linux
#
# To install use :
# $ PREFIX=/dummyinstalldir make -f Makefile.linux install
# or :
# $ INSTALLPREFIX=/usr/local make -f Makefile.linux install
# or :
# $ make -f Makefile.linux install
#
# if your system hasn't iptables libiptc headers and binary correctly
# installed, you need to get iptables sources from http://netfilter.org/
# ./configure them and build them then miniupnpd will build using :
# $ IPTABLESPATH=/path/to/iptables-1.4.1 make -f Makefile.linux
