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