+ Multiple output support should now be usable. A derivation
+ can declare that it wants to produce multiple store paths by
+ saying something like
+
+outputs = [ "lib" "headers" "doc" ];
+
+ This will cause Nix to pass the intended store path of each output
+ to the builder through the environment variables
+ lib, headers and
+ doc. Other packages can refer to a specific
+ output by referring to
+ pkg.output,
+ e.g.
+
+buildInputs = [ pkg.lib pkg.headers ];
+
+ If you install a package with multiple outputs using
+ nix-env, each output path will be symlinked
