<para>The Ports Collection supports parallel installation of multiple
Python versions. Ports should make sure to use a correct
<command>python</command> interpreter, according to the user-settable
<makevar>PYTHON_VERSION</makevar> variable. Most prominently, this
means replacing the path to <command>python</command> executable in
scripts with the value of <makevar>PYTHON_CMD</makevar>
variable.</para>
<para>Ports that install files under <makevar>PYTHON_SITELIBDIR</makevar>

package name embeds the version of Python they are installed
into.</para>
