The easiest way to set up a development environment for Guix is, of
course, by using Guix! The following command starts a new shell where
all the dependencies and appropriate environment variables are set up to
installation instructions (@pxref{Requirements}).

The Perfect Setup to hack on Guix is basically the perfect setup used

@cindex free software

software that conveys these four freedoms.
In addition, the GNU distribution follow the

the word @code{python}.
