  50 First, select *which* of the tools you want to build,
  51 with --{enable,disable}-{ghc,nofib,happy,haggis}.
  52 (The default is: only GHC (Glasgow Haskell compiler).)
  53
  54 Second, you may set one of a few applies-in-all-cases options.
  55 For example, --with-tmpdir=/usr/tmp.
  56
  57 Then you may set various options which are specifically for the
  58 tools you choose in step 1.  For GHC, perhaps --enable-concurrent.
  59 For NoFib, perhaps --enable-all-tests.  And so on.
  60
  61 The rest of this message lists all of the configure options.  If the
  62 option is enabled by default, the message says how to disable it.  And
  63 vice versa.
  64
  65 If you are confused, don't forget the installation documents that came
  66 with the software!
