[Nfd-dev] How to see data retrieve / download time using "ndngetfile" command?

Hello,
you can check out our chunks implementation (a little different from the
NDN cat/put chunks one) that implements a GObject layer for
progress/complete signal if that's usefull for you:
https://github.com/endlessm/endless-ndn/blob/master/eos_data_distribution/ndn/chunks.py
