From: Martin Becze
Subject: [bug#38408] [PATCH v9 8/8] guix: import: parametrized importing of dev dependencies
Date: Tue, 4 Feb 2020 07:18:25 -0500

This changes the behavoir of the recusive crate importer so that it will
include the importing of development dependencies for the top level package
but will not inculded the development dependencies for any other imported 
package.
