 ## Troubleshooting ##
 * If when starting the image you get error messages like "This interpreter (vers. 6505) cannot read image file (vers. 68021).", (68021 or some other reasonable number) it means you image and VM are mismatched. For example, one of them is Spur and the other is pre-Spur, or one of them is 32 bits and the other is 64 bits.
 * If when starting the image you get error messages like "This interpreter (vers. 6505) cannot read image file (vers. 1007290890).", (1007290890 or some other absurd number) it means your git installation is breaking the files. It is usually best to configure git not to do any conversion on files.
