+"Objects of this class are stored in the `wx.LayoutConstraints` class as
+one of eight possible constraints that a window can be involved in.
+You will never need to create an instance of
+wx.IndividualLayoutConstraint, rather you should create a
+`wx.LayoutConstraints` instance and use the individual contstraints
+that it contains.", "
+
+Constraints are initially set to have the relationship
+wx.Unconstrained, which means that their values should be calculated
+by looking at known constraints.
+
+The Edge specifies the type of edge or dimension of a window.
+
+Edges
+------
+ ================== ==============================================
+ wx.Left The left edge.
+ wx.Top The top edge.
+ wx.Right The right edge.
+ wx.Bottom The bottom edge.
+ wx.CentreX The x-coordinate of the centre of the window.
+ wx.CentreY The y-coordinate of the centre of the window.
+ ================== ==============================================
+
+
+The Relationship specifies the relationship that this edge or
+dimension has with another specified edge or dimension. Normally, the
+user doesn't use these directly because functions such as Below and
+RightOf are a convenience for using the more general Set function.
+
+Relationships
+-------------
+ ================== ==============================================
+ wx.Unconstrained The edge or dimension is unconstrained
+ (the default for edges.)
+ wx.AsIs The edge or dimension is to be taken from the current
+ window position or size (the default for dimensions.)
+ wx.Above The edge should be above another edge.
+ wx.Below The edge should be below another edge.
+ wx.LeftOf The edge should be to the left of another edge.
+ wx.RightOf The edge should be to the right of another edge.
+ wx.SameAs The edge or dimension should be the same as another edge
+ or dimension.
+ wx.PercentOf The edge or dimension should be a percentage of another
+ edge or dimension.
+ wx.Absolute The edge or dimension should be a given absolute value.

+DocStr(wxLayoutConstraints,
+"**Note:** constraints are now deprecated and you should use sizers
+instead.
+
+Objects of this class can be associated with a window to define its
+layout constraints, with respect to siblings or its parent.
+
+The class consists of the following eight constraints of class
+wx.IndividualLayoutConstraint, some or all of which should be accessed
+directly to set the appropriate constraints.
+
+ * left: represents the left hand edge of the window
+ * right: represents the right hand edge of the window
+ * top: represents the top edge of the window
+ * bottom: represents the bottom edge of the window
+ * width: represents the width of the window
+ * height: represents the height of the window
+ * centreX: represents the horizontal centre point of the window
+ * centreY: represents the vertical centre point of the window
+
+Most constraints are initially set to have the relationship
+wxUnconstrained, which means that their values should be calculated by
+looking at known constraints. The exceptions are width and height,
+which are set to wxAsIs to ensure that if the user does not specify a
+constraint, the existing width and height will be used, to be
+compatible with panel items which often have take a default size. If
+the constraint is ``wx.AsIs``, the dimension will not be changed.
