   _buddy-auth_ exposes two ways to do it:
   
   * Using a _wrap-access-rules_ middleware.
  -* Using a _restrict_ decorator for assigning specific rules handlers to concrete ring handler.

   Here are couple of examples of how we could do it:
   
  
positive.code: 
  ==== Rules Handlers
  
  The rule handler is a plain function that accepts a request as a parameter and should return
  `accessrules/success` or `accessrules/error`.
  
  The `success` is a simple mark that means that handles passes the validation and `error` is a mark
  that means the opposite, that the handler does not pass the validation. Instead of returning plain
  boolean value, this approach allows handlers to return errors messages or even a ring response.

  === Access Rules
  
  The access rules system is another part of authorization. It consists of matching an url
  to specific access rules logic.
  
  The access rules consists of an ordered list. This contains mappings between urls and
  rule handlers using link:https://github.com/weavejester/clout[clout] url matching syntax
  or regular expressions.
  
  .This is an example of an access rule using the clout syntax.
