MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * doc/guix.texi (Build Systems): Clearly distinguish between the package that provides the Python interpreter for the build and the package that is to be built. Also, mention why one might want to use a specific Python version.
