FYI -- I was unable to create a stand-alone fruit basket executable with
the /clr or /clr:pure parameters. Dependencies to other files remained,
which had to be available on the existing search paths, specified in a
seperate manifest file, or included in the same directory as the
executable. The /clr:safe parameter, however, did create a stand-alone,
.NET-based executable.
