Abstract:

    Keyring WinMain() and application support

    georgema        000310  updated
    georgema        000501  used to be EXE, changed to CPL

Comments:
    This executable is the control panel applet to allow a user some control 
    over the contents of the Windows Keyring, the so-called "Geek UI".  It was 
    originally an EXE, but that architecture is not as optimized for merging 
    with other control panel applets.  It has been changed to a CPL executable, 
    and can be either left as a CPL if it is desired that it should show up 
    automatically in the master control panel window, or rahter renamed to 
    a DLL file extension if it is desired that a control panel applet container
    application should load it explicitly without it otherwise being visible 
    to the system.

Environment:
    WinXP

/**********************************************************************

CPlApplet is the entrypoint for a control panel applet.  This entry point
is used by keymgr.cpl, generated in the keycpl project.  The decision to 
implement this cpl functionality in keymgr.dll, rather than in keymgr.cpl,
allows the implementation of keymgr to be contained entirely within 
keymgr.dll, as a common component, without need to update the cpl version 
if changes are made to the dll.  The cpl is a very thin wrapper for the dll.
