Cloning ghc-7.8

How would I get a GHC 7.8 branch repo? Something like git clone http://git.haskell.org/ghc.git ghc-7.8-branch cd ghc-7.8-branch ./sync-all get git checkout ghc-7.8 git submodule update Is that enough? What about the non-submodule libraries? Do I need to do any more pull/get stuff? This would be another great entry on the workflow page. Thanks Simon
