Architecture
============

Start up proccess
-----------------

See ``bin/cc-node``.

Summary of the steps:

* First parse command line options and configuration file
* Then register signal handling for ``SIG_USR1`` (reload configuration) and
  ``SIG_TERM`` (terminate process).
* Switch to a daemon context
* Reload logging configuration
* Instanciate and launch a :class:`ccnode.node.Node` in background
* Enter main loop that consist of waiting for signals and reloading configuration
  if needed.
