title: Dynamic business rules engine for ruby on rails
body: <p>I have an application which will require a "dynamic business rules" engine. Some of the business rules changes very frequently. Some of then applies for a limited set of business accounts. For example: my customer have a process where they qualify stores, based on their size, number of the sales person, number of products, location, etc. But he manages different account, and each account give different "weights" to each attribute.</p>
  
  <p>How do I implement this engine using Ruby? I know Java has drools, but I find drools annoying and complex. And I prefer not having to use JRuby...</p>
  
  <p>Regards,</p>
