+The options ``minLat`` and ``maxLat`` determine the start and end of each
+meridional transect (in degrees).  The option ``longitudes`` is a list or
+numpy array of longitudes for each transect, e.g.::
+
+  longitudes = numpy.linspace(0, 330, 12)
+
+produces 12 transects spaced every 30 |deg|.
+
+The user can select only to plot a subset of the supported fields by adding
+only the desired field names to ``fieldList``.  Only potential temperature
+and salinity are currently available.
+
+Ater the ``woaTransects`` section, there is a section for each supported field
+specifying the information related to the colormap.
