Version 4.1:
------------
8/28/00 rth: Carbonized the source and header files for use under Mac OS X

7/17/96 dmb: Give client more control over menu insertion & deletion

	1. Frontier 4.1 now allows client to do actual menu insertion and 
	deletion. Even for default operation, we use these callbacks so

	4. if the (component) server disappears unexpectedly, set fldirtysharedmenus

Version 3.0.2:

	If you're using Think C/Symantec C++, make sure you're

	even the Frontier 1.0 protocol.
	
	2. Added a ComponentInstance fie
