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