DEPRECATED - the samples directory is now part of the BOINC tree

David  7 April 2006
    - extended upper_case so that it draws graphics
        (text, image, bouncing ball)
        NOTE: to get this to work, you have to put in your build dir:
            - file called "logo.jpg" (the image)
            - Helvetica.txf
            - a file called "in" (any old text)

        It works now, more or less, on Windows.
        - wrapper no longer copies input/output files.

            in the file reference instead.

        This lets you pass different command-line args to the app
        for different workunits,
        without creating a new app version per workunit.

    NOTE: actually, I don't think this is necessary;
    the job file can be part of the workunit, not part of the app version.

        The first process handles suspend/resume messages
        by signaling the 2nd process.
