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:
    Win98, Win2000
