|  I guess we could add
|  
|  $root/ghc-stage1 (shell script)
|  $root/ghc-stage2 (shell script)
|  
|  As long as we understand that those are just convenience scripts.
|  
|  Why $root? Because we can have multiple build directories for different
|  configurations. Thus putting the scripts into the ghc folder would not
|  know which root you wanted. This for the default root this would be:
|  
|  _build/ghc-stage1
|  _build/ghc-stage2
|  
|  Does that sound like an intermittent solution?
|  
|  Cheers,
|    Moritz

|  Yes, that works.  But perhaps a script to get to it would be helpful,
|  otherwise invoking stage1 will look entirely different to invoking stage2.
|  Not a bid deal, I grant you!
