to be built for a specific version of the Python interpreter, which
might be necessary if the package is only compatible with a single
interpreter version.
+
+By default guix calls @code{setup.py} under control of
+@code{setuptools}, much like @command{pip} does. Some packages are not
+compatible with setuptools (and pip), thus you can disable this by
+setting the @code{#:use-setuptools} parameter to @code{#f}.
