description             ProjectCCNx implementation of Content Centric Networking (CCN) / \
                        Named Data Networking (NDN) architecture

long_description        Project CCNx(r) exists to develop, promote, and evaluate a new \
                        approach to communication architecture we call content-centric \
                        networking.  We seek to carry out this mission by creating and \
                        publishing open protocol specifications and an open source \
                        software reference implementation of those protocols.  We provide \
                        support for a community of people interested in experimentation, \
                        research, and building applications with this technology, all \
                        contributing to its evolution.

notes "

You can add the following line into \"${ccnxdir}/ccndrc\" in order to automatically
start ccnx repo for the /ndn/keys prefix:

    CCNR_GLOBAL_PREFIX=/ndn/keys

For more information and documentation, refer to man pages and http://www.ccnx.org website.

If you have your public key signed by NDN testbed operators and you installed the certificate
\(using ndn-install-pubcert command\), you can enable automatic configuration of the default
route using your key.  To do so, you need to run the following commands once:

  # extract public key from ccnx user
  sudo HOME=${ccnxdir} ndn-extract-public-key > /tmp/ccnx.pem

  # sign public key of the ccnx user
  ndn-sign-key -i \"ccnx-autoconfig\" /tmp/ccnx.pem

  # install certification of the public key
  sudo HOME=${ccnxdir} ndn-install-pubcert /tmp/ccnx.pubcert
