Hi Matti,

ndnputfile/ndngetfile comes from repo-gn, you might have to install it.
You can also check out ndnputchunk3, this will also do what you want. If
you want I have created a text file sender/receiver by (modifying earlier
producer/sender code) for large chunks of data, more like bulk transfer. I
have tested my code for one sender and one receiver and haven't tested for
more than one receiver(maybe some optimization have to done there)
