unregisterized

[Serge D. Mechveliani]

People,

Please, where the build guide (.pdf, .html) can be download from?
Does the source GHC distibution include the build guide?
Does the GHC  user_guide  include the build guide?
If not, then -- why?

How to build  unregisterized ghc-7.4.1 from source?

(For many years I read "registerized" in the GHC related messages as 
"registered" and wondered of why do they care for a user to register a 
build!)

Thanks,
