60<P>
61These modules are not normally available for import; additional work
62must be done to make them available.
63
64<P>
65Those which are written in Python will be installed into the directory
66<span class="file">lib-old/</span> installed as part of the standard library. To use
67these, the directory must be added to <code>sys.path</code>, possibly using
68<a class="envvar" id='l2h-5293' xml:id='l2h-5293'>PYTHONPATH</a>.
69
70<P>
71Obsolete extension modules written in C are not built by default.
72Under <span class="Unix">Unix</span>, these must be enabled by uncommenting the appropriate
73lines in <span class="file">Modules/Setup</span> in the build tree and either rebuilding
74Python if the modules are statically linked, or building and
75installing the shared object if using dynamically-loaded extensions.
