 # NumPy static imports for Cython
 #
+# If any of the PyArray_* functions are called, import_array must be
+# called first.
+#
 # This also defines backwards-compatability buffer acquisition
 # code for use in Python 2.x (or Python <= 2.5 when NumPy starts
 # implementing PEP-3118 directly).
-
-
+#
 # Because of laziness, the format string of the buffer is statically
 # allocated. Increase the size if this is not enough, or submit a
 # patch to do this properly.
