+#
+# matplotlib now has a PolarAxes class and a polar function in the
+# matplotlib interface.  This is considered alpha and the interface
+# may change as we work out how polar axes should best be integrated
+#
+# The only function that has been tested on polar axes is "plot" (the
+# matlab interface function "polar" calls ax.plot where ax is a
+# PolarAxes) -- other axes plotting functions may work on PolarAxes
+# but haven't been tested and may need tweaking.
+#
+# you can get get a PolarSubplot instance by doing, for example
+#
+#   subplot(211, polar=True)
+#
+# or a PolarAxes instance by doing
+#   axes([left, bottom, width, height], polar=True)
+#
+# The view limits (eg xlim and ylim) apply to the lower left and upper
+# right of the rectangular box that surrounds to polar axes.  Eg if
+# you have
+#
+#  r = arange(0,1,0.01)
+#  theta = 2*pi*r
+#
+# the lower left corner is 5/4pi, sqrt(2) and the
+# upper right corner is 1/4pi, sqrt(2)
+#
+# you could change the radial bounding box (zoom out) by setting the
+# ylim (radial coordinate is the second argument to the plot command,
+# as in matlab, though this is not advised currently because it is not
+# clear to me how the axes should behave in the change of view limits.
+# Please advise me if you have opinions.  Likewise, the pan/zoom
+# controls probably do not do what you think they do and are better
+# left alone on polar axes.  Perhaps I will disable them for polar
+# axes unless we come up with a meaningful, useful and functional
+# implementation for them.
