166 Since <application>Python 2</application> is in maintenance mode, and
167 <application>Python 3</application> is recommended by upstream for
168 development, you probably do not need to install the documentation.
169 However, if you still want to install documentation for both
170 <application>Python</application> versions, be sure to define the
171 <envar>PYTHONDOCS</envar>
172 variable for the version you want to use, each time you need to consult
173 the documentation. If you have downloaded the preformatted documentation
174 from <ulink url="http://docs.python.org/download.html"/>, install it
175 as the <systemitem class="username">root</systemitem> user:
