description         Named Data Networking Forwarding Daemon

long_description \
    NFD is a network forwarder that implements and evolves together with the \
    Named Data Networking (NDN) protocol.  The main design goal of NFD is \
    to support diverse experimentation of NDN technology.                 \
    The design emphasizes modularity and extensibility to allow easy      \
    experiments with new protocol features, algorithms, new               \
    applications. We have not fully optimized the code for                \
    performance. The intention is that performance optimizations are one  \
    type of experiments that developers can conduct by trying out         \
    different data structures and different algorithms\; over time, better \
    implementations may emerge within the same design framework.

notes "

To start NFD and ensure it is started when system boots:

    nfd-start

To stop NFD and disable auto-start when system boots:

    nfd-stop

NFD log files are located in ${prefix}/var/log/ndn/

Configuration file is in ${prefix}/var/etc/ndn/
