// Class: CDocfileUnmarshalFactory (dfuf)
//
// Purpose: Implements OLE2 unmarshalling support
//
// Interface: See below
//
// History: 25-Jan-93 DrewB Created
//
// Notes: This class is intended to be used statically
// rather than dynamically with initialization being
// deferred past construction to avoid unnecessary
// initialization of static objects.
// Init should be called to initialize in place of
// a constructor.
