+Abstract:
+
+    This file turns 16 byte packing of structures on.  (That is, it disables
+    automatic alignment of structure fields.)  An include file is needed
+    because various compilers do this in different ways.  For Microsoft
+    compatible compilers, this files uses the push option to the pack pragma
+    so that the poppack.h include file can restore the previous packing
+    reliably.
+
+    The file poppack.h is the complement to this file.
