CopyDirToDir.cs

/* shows how to count the number of top-level 
subdirectories within a given directory

To compile, use build.bat. Or, at the command line: 
    csc /out:copydir.exe *.cs  

Here is the structure of this example program 
and associated directories, on disk:

examples/CopyDirToDir
    - copyDir.cs (file)
    - boo 
        - chirp (subdirectory)
            * tweet (file)
            * peep (file)
        - squawk (subdirectory)
            - buzzard (subdirectory)
                * caw (file)
                
The above directory structure will be mirrored to whatever directory
you create.
