+What is it for?

+
+Why do I need it?
+-----------------
+Usually config files for Erlang software is just a bunch of Erlang terms.
+It is hard to read, write, parse and validate. And sometimes you need
+to handle config reloading. All this makes pain in ass and puts your code
+in mess.
+Nakaz uses YAML for config files (which is human-readable and clean),
+-record specs as config schema definition, has schema validation and has
+support for config reloading interface and callbacks.
