COMMENT:

\b OILMENUS Module \b0

The OilMenus module provides a set of functions used for initialising, updating and 
deinitialising the menu system. The new menu consists of two dynamic menu structures. The 
first is a platform independent structure which resides in the Kernel. This structure is 
created and and maintained by functions which reside in the OilMenus Module. The fundamental
component of this structure is the MenuItem class. The second menu structure is a Windows
specific one. It is composed of CMENU objects. The creation and deletion of these objects 
is again handled by functions which reside in the OilMenus module. Conversion between these
menu structures occurs during initialisation and update (i.e.  new menu items are added to 
an existing menu). The reasons for maintaining two menu structures are mainly to do with portability and 
flexibility.
