[Squeakfoundation]base image distribution

    MobVM uses the services provided by the OS (Windows) to download
    everything except SqM.exe, SqMOM.dll and SqM.ini.

    Straight C is used to access the OS services, no Slang, no primitives.
    During the bootstrapping phase, there is no image (at the early stage,
    not even the interpreter.)

    If you do a 'Smalltalk listLoadedModules' you will see the order in
which
    the plugins were loaded. On my system, it looks like this:

#('LargeIntegers v1.2 5 September 2002 (e)' 'B2DPlugin 5 September 2002 (e)'
'FloatArrayPlugin 5 September 2002 (e)' 'Matrix2x3Plugin 5 September 2002
(e)' 'BitBltPlugin 9 November 2002 (e)' 'MiscPrimitivePlugin 5 September
2002 (e)' 'WindowPlugin September 2002 (e)' 'DropPlugin 5 September 2002
(e)' 'FilePlugin 5 September 2002 (e)' 'SecurityPlugin 5 September 2002 (e)'
'MegaVI4InterpreterPlugin Halloween 2002 (e)' 'ModManPlugin Sep. 2002 (e)'
'PlatformPlugin September 2002 (e)' 'PlugManPlugin September 2002 (e)'
'SqMOM September 2002 (e)' 'SqPOP September 2002 (i)')

    'LargeIntegers'  was the last plugin loaded. SqM.exe is itself counted
as
    a plugin (the internal name is 'SqPOP')

    However, this doesn't mean that one cannot write a primitive
    to download file based on services exposed by SqMOM plugin.

    Such a primitive is only operational after a suitable set of objects
    are loaded into the OM and properly initialised.

    The plugins I was talking about are the ones needed
    before SqueakMap came into action.

    As soon as SqueakMap is active it should take over,
    because it has more knowledge of the packages and plugins.

    Sorry for the confusion.

     Cheers,

    PhiHo.
