AC_MSG_NOTICE([********************************************
You can compile GNUnet with
	make
now. After that, run (if necessary as 'root')
        make install
to install everything. You may want to create a new user account
to run the GNUnet service:
	adduser gnunet
You also need to create an configuration file that should
specify the path where GNUnet should store data.  For example,
you could store in "/etc/gnunet.conf" the following lines:

[[PATHS]]
SERVICEHOME = /var/lib/gnunet
DEFAULTCONFIG = /etc/gnunet.conf

Now, in order to start your peer, run as the 'gnunet' user
	gnunet-arm -s

Each GNUnet user should also create an (at least initially) empty
configuration file:
	mkdir $HOME/.gnunet/
	touch $HOME/.gnunet/gnunet.conf
	
Optionally, download and compile gnunet-gtk to get a GUI.
