Attached is a recipe for GNU Guix to compile Emacs from source.  (It
inherits from the Emacs package definition in Guix.)  You can just drop
this file somewhere (for example in ~/my-packages) and then run

  GUIX_PACKAGE_PATH=~/my-packages/ guix build emacs-xwidget

It will fetch commit 0cfb6600a837f67997aef027f0183aca9df05df9 from the
git repository on savannah, run autogen.sh and build Emacs with the
xwidget feature.
