I always get the documentation, but there are some disadvantages to it. You 
don't see things the way a normal user who is copying and pasting the examples 
would see them. When I went through all of the regtests a couple of months ago, 
there were some issues that only appeared if you compiled the actual code in 
the regtests. I have seen some of the discussion about the regtest comparison 
checker but a) it was a bit too complex for me to follow and b) I don't have 
access to windows.
