   6 == RPC daemon

   8 In 'LEDE' we commonly use 'ubus' for all kinds of communication. It can provide info from various software as well as request various actions. Nevertheless, not every part of 'LEDE' has a deamon that can register itself using 'ubus'. For an example 'uci' and 'opkg' are command-line tools without any background process running all the time.

  10 It would be not efficient to write a deamon for every software like this and run them independently. This is why 'rpcd' was developed. It's a tiny deamon with support for plugins using trivial 'API'. It loads library `.so` files and calls init function of each of them.

  12 === Default plugins
  13
  14 There are few small plugins distributed with the 'rpcd' sources. Two of them ('session' and 'uci') are built-in, others are optional and have to be build as separated `.so` libraries. Apart from that there are other projects providing their own plugins.
