Building GHC

[Dominic Steinitz]

When I look at the instructions

http://hackage.haskell.org/trac/ghc/wiki/Building/GettingTheSources

they say the distribution is split in two but when I look at

http://darcs.haskell.org/

it seems to be split in three

ghc-HEAD-2007-12-16-..> 16-Dec-2007 14:25  102M
ghc-HEAD-2007-12-16-..> 16-Dec-2007 14:20   92M
ghc-HEAD-2007-12-16-..> 16-Dec-2007 14:12   57M

I'm assuming I unpack these on top of each other but I'd be grateful if
someone could confirm this.

Thanks, Dominic.
