Hadrian

[Artem Pelenitsyn]

Hello Simon, Andrey,

For “How to use Hadrian wikipage”, maybe Simon wanted this one from the GHC
Wiki:

https://ghc.haskell.org/trac/ghc/wiki/Building/Hadrian/QuickStart

It does mention the verbose flag, but does not really explain that you can
get what Simon wants, I believe.

Best wishes,
Artem
