+Note [Binary distributions]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Hadrian produces binary distributions under:
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>.tar.xz
+
+It is generated by creating an archive from:
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>/
+
+It does so by following the steps below.
+
+- make sure we have a complete stage 2 compiler + haddock
+
+- copy the bin and lib directories of the compiler we built:
+ <build root>/stage1/{bin, lib}
+ to
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>/{bin, lib}
+
+- copy the generated docs (user guide, haddocks, etc):
+ <build root>/docs/
+ to
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>/docs/
+
+- copy haddock (built by our stage2 compiler):
+ <build root>/stage2/bin/haddock
+ to
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>/bin/haddock
+
+- use autoreconf to generate a `configure` script from
+ aclocal.m4 and distrib/configure.ac, that we move to:
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>/configure
+
+- write a (fixed) Makefile capable of supporting 'make install' to:
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>/Makefile
+
+- write some (fixed) supporting bash code for the wrapper scripts to:
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>/wrappers/<program>
+
+ where <program> is the name of the executable that the bash file will
+ help wrapping.
+
+- copy supporting configure/make related files
+ (see @bindistInstallFiles@) to:
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>/<file>
+
+- create a .tar.xz archive of the directory:
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>/
+ at
+ <build root>/bindist/ghc-<X>.<Y>.<Z>-<arch>-<os>.tar.xz
+
+
+Note [Wrapper scripts and binary distributions]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Users of Linux, FreeBSD, Windows and OS X can unpack a
+binary distribution produced by hadrian for their arch
+and OS and start using @bin/ghc@, @bin/ghc-pkg@ and so on
+right away, without even having to configure or install
+the distribution. They would then be using the real executables
+directly, not through wrapper scripts.
+
+This works because GHCs produced by hadrian on those systems
+are relocatable. This means that you can copy the @bin@ and @lib@
+dirs anywhere and GHC will keep working, as long as both
+directories sit next to each other. (This is achieved by having
+GHC look up its $libdir relatively to where the GHC executable
+resides.)
+
+It is however still possible (and simple) to install a GHC
+distribution that uses wrapper scripts. From the unpacked archive,
+you can simply do:
+
+ ./configure --prefix=<path> [... other configure options ...]
+ make install
+
+-}
