[rules-users] custom rule creation/parsing

[Edson Tirelli]

   Yes, simplest thing to do is to use the descriptors. There is no
documents yet (help welcome), but one can use the DRL/XML dumpers to test if
what you are generating is what you want.

   In the end, the way we support multiple languages (DRL, XML, CLP...) is
to use the descriptors as an intermediate format, so, any framework/language
driver you ends up creating will in the end generate descriptors.
