+## Called without any arguments, or with @var{property}/@var{value} pairs,
+## contruct a new axes.  For accepted properties and corresponding
+## values, see @code{set} function.
+##
+## Called with a single axes handle argument @var{h}, the function makes
+## @var{h} the current axis.  It also restacks the axes in the
+## corresponding figure so that @var{h} is the first entry in the list
+## of children.  This causes @var{h} to be displayed on top of any other
+## axes objects (Z-order stacking).
