Or, if you do not want to get into the specifics of how
to manually install setuptools/pip, it would probably be
better to just refer the user to the 'ensurepip' module
for the initial installation and tell him to upgrade
whatever is needed from there without going in to any
further details here.

'ensurepip' module itself is documented elsewhere (https://docs.python.org/3.4/library/ensurepip.html),
and that documentation should perhaps be updated to
include enough information (or references to external
documentation containing that information) for the
user to be able to perform the upgrades.
