creation, conversion and rodolog commit. Image creation support is not
present yet and the executable has not been added to standard compile yet.
TODO #1: add floppy and hard disk image creation support (from bximage.c)
TODO #2: implement support for conversion to vmware and vpc formats
TODO #3: add MSVC (nmake and workspace) support
