My intention is not to criticize, just saying that in the 3 documents contain errors
lommont is wonderful, but there are errors in this document

LDQ = CD , not exits, instead there  STD, wrong
And other more errors
So in other documents.


It could also mean errors in them, but not the idea.
The problem for me and other beginners, is that you have to look hard to find the right information, Aaron did a great job to go collecting and sorting all, the truth is that until I saw this thread was lost with errors, a loss weeks.
Now thanks to the link from Aaron, everything improves.
My commitment is to put everything in one place, we can all improve, as wikipedia and leave things the right way, for posterity.
