Example how to use the code generator libt2n-codegen.
This example may be build during the build of libt2n or it may be build seperately using a
installed version of libt2n.

To build it seperately using a installed version of libt2n:
autoreconf && ./configure && make && make distcheck

if it does not work you may have to move the example-codegen out of the libt2n directory and
pass some options to autoreconf
I use something like:
tar xzvf libt2n-0.1.tar.gz
mv libt2n-0.1/example-codegen . 
cd example-codegen
# get configure script created and missing autotools helper files installed
# if you installed libt2n in some non-standard directory you might have to pass
# -M pathtolibt2n.m4
autoreconf -f -i
./configure && make && make distcheck
