+### Python Options:
+
+* **PyIlmBase\_Python2\_SITEARCH\_REL**
+
+  This will normally be computed based on where the python2 binary and site-packages live and
+  then be a relative path based on the root of those. For example, if site-packages is in
+  ``/usr/lib/python2.7/site-packages`` and the python binary is ``/usr/bin/python2.7``, this
