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 "
In order repo to work, you need to add the following lines at the end of your 
\[~/.bash_profile\]:

  export CCNR_DIRECTORY=${prefix}/etc/ccnx/repo

To configure environment variables for ccnd, edit your 
\[${prefix}/etc/ccnx/ccndrc\]. For example,
  
  CCND_LOG=${prefix}/var/log/ccnd.log
  CCND_DEBUG=16

To add static FIB entries, edit your \[${prefix}/etc/ccnx/ccnd.conf\]. 
For example,

  add ccnx:/ccnx.org udp 224.0.23.170 59695

Upon any networking change event (new connection or awaking from the sleep 
phase), all static FIB entries will be reapplied automatically.

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