+    This is an abstract superclass for geometry controlling objects.
+    While old smalltalks used relative origin/extent/corner and absolute
+    origin/corner/extents, these mechanisms are now being removed from the
+    view itself into geometry controlling objects, which are given a superviews
+    size and are to return a components size upon request.
+    This allows more flexible geometry management, since any algorithm can
+    be implemented (if the existing ones are not sufficient, add you own subclass
+    and instal it as layout-object in your view).
+
+    See more info & examples in concrete subclasses:
+	LayoutOrigin LayoutFrame AlignmentOrigin
+
+    Notice: this class was implemented using protocol information
+    from alpha testers - it may not be complete or compatible to
+    the corresponding ST-80 class. If you encounter any incompatibilities,
+    please forward a note to the ST/X team.
