[rules-users] XOR Rules

[Jeremy Ary]

The Developer's Guide is a useful tool, and the cookbook is a good
reference as well, but both are supplemental to the documentation as they
each cover portions of functionality, but neither covers it in its
entirety. To do so would be quite the task for a single book, so I would
recommend a good read through the Expert page followed by reading through
the Introduction pages. Seems backwards, but I've found that for me, the
Expert guide builds a good base to understanding the "What's New" stuff
found in the Introduction. In any case, even if it doesn't all make sense
now, you'll likely remember keywords that you can refer back to later when
you need them.
