====== Rules Wiki ======
This part of the wiki is dedicated to general rule-related topics, including:
  * expert systems (ES)
  * rule-based systems (RBS)
  * business rules (BR)
  * etc.
It serves both as a research and didactic resource.


This wiki is created by the members of the HeKatE project, but also by other researchers and students.
It //is not// related to HeKatE itself, or its development.

The wiki is //english//-only, and all of the pages are in the __rules__ namespace.
