-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-#### Restricted mode
-##
-
-#
-# If the `ntk_restricted_mode' option is set to 1, NetsukukuD will be started
-# in restricted mode to be compatible with Internet. In the restricted mode, 
-# only IPs of the largest private subnet (i.e. 10.x.x.x) are chosen.
-#
-# If `ntk_restricted_class' is set to 1 the IPs will be chosen from the
-# 172.16.0.0-172.31.255.255 range (use this option only if you can't use the 
-# 10.x.x.x class).
-#
-#ntk_restricted_mode	= 0
-#ntk_restricted_class	= 0
-
-
-##
-#### Internet connection
-##
-
-#
-# * * If you have an Internet connection please fill this options. * *
-#
-# We are assuming that you are running in restricted mode since you want to
-# be both in Netsukuku and Internet. So, if you have an internet connection
-# set `internet_connection' to 1. Note that ntkd will overwrite any default
-# route if this option is set to 0 and the shared Internet connections of 
-# other nodes are used.
-#
-# Set the `internet_gateway' option to the IP of the gateway you use to reach 
-# the Internet and specify the network interface too, for example:
-# "internet_gateway = 192.168.1.1:eth0". This option is necessary only if you
-# don't have the default route set when you run NetsukukuD (i.e. you haven't
-# connected yet), otherwise, leave it commented.
-#
-# You have also to set your upload and download bandwidth in 
-# `internet_upload_rate' and `internet_download_rate'. It is expressed in Kb/s,
-# so if you have a line which maximum can do: 640 Kb/s in dwload and 30 Kb/s in 
-# upload, set them to 640 and 30.
-#
-# `internet_ping_hosts' is a list of Internet hosts which will be pinged to
-# verify if the connection is alive, you can use the default hosts.
-#
-# If you want to share your Internet connection among other Netsukuku nodes, 
-# set `share_internet' to 1.
-#
-# Set `shape_internet' to 1 if you want to shape your outgoing
-# Internet traffic.
-#
-# `use_shared_internet' specifies if you want to use the Internet connections
-# shared by the Netsukuku nodes. Set it to 0, if you want to rely only on your
-# connection (if any).
-# 
-#internet_connection	= 1
-#internet_gateway	= 192.168.1.1:eth0

-##
-#### ANDNA
-##
-
-#
-# To disable the start of the ANDNA daemon at the launch of ntkd, set
-# this option to 1. Note that when the ANDNA daemon is disabled, the andna
-# system will not work at all, so it will be impossible to resolve, register
-# or update hostnames.
-#
-#disable_andna		= 0
-
-#
-# When NetsukukuD starts it modifies /etc/resolv.conf writing in the first
-# line "nameserver 127.0.0.1". The old /etc/resolv.conf is copied in
-# /etc/resolv.conf.bak. When the daemon is closed /etc/resolv.conf is
-# restored. If you want to disable this set disable_resolvconf to 1.
-# If it is disabled you won't be able to resolve hostnames!
-#
-#disable_resolvconf	= 0
-
-
-##
-#### Limits
-##
-
-#
-# How many connection the netsukuku daemons can simultaneusly handle.
-#
-#ntk_max_connections		= 512
-
-# How many simultaneusly connections to the daemons from a single host are
-# allowed.
