 # Cartopy and basemap
 # -------------------
 #
-# Geographic axes in ProPlot use either `cartopy`_ or `basemap`_ as "backends".
-# When you request a geographic projection, the axes-creation command returns
-# a `proplot.axes.GeoAxes` instance(s) that uses either cartopy or basemap
-# under the hood. The `proplot.axes.GeoAxes` subclass has its own
-# `~proplot.axes.GeoAxes.format` command that :ref:`manages geographic features
-# <ug_geoformat>` like meridional and parallel gridlines and land mass outlines
-# with the same syntax for either backend. A few details:
-#
-# * Cartopy is the default backend. When you request projections with
-#   cartopy as the backend, the returned axes is a subclass of cartopy's
-#   `cartopy.mpl.geoaxes.GeoAxes`. Under the hood, invoking
-#   `~proplot.axes.GeoAxes.format` with cartopy as the backend changes map bounds using
-#   `~cartopy.mpl.geoaxes.GeoAxes.set_extent`, adds major and minor gridlines using
-#   `~cartopy.mpl.geoaxes.GeoAxes.gridlines`, and adds geographic features using
-#   `~cartopy.mpl.geoaxes.GeoAxes.add_feature`. If you prefer, you can use the
-#   standard `cartopy.mpl.geoaxes.GeoAxes` methods just like you would in cartopy.
-#   If you need to use the underlying `~cartopy.crs.Projection` instance, it is

 # * Basemap is an alternative backend. To use basemap, set :rcraw:`basemap` to
-#   ``True`` or pass ``basemap=True`` to the axes-creation command. When you request
-#   projections with basemap as the backend, the resulting axes class redirects
-#   the plotting methods plot, scatter, contour, contourf, pcolor, pcolormesh,
