User guide available and/or list of available commands to use linq optimizer with?

[ooples]

Is there a wiki or user guide showing the full list of commands that this library can optimize or any user reference guide showing a full list? I'm new to using this library and I'm having trouble figuring out how it works exactly. I can see in the home page that you seem to add AsQueryExpr() to any item you are using for a linq query and there is also a parallel version AsParallelQueryExpr(). Is there a rule of thumb for when to use the parallel version vs the regular version?
