959ccb23 | 2 | Root include file for Mde Package Base type modules\r |

818ff8c2 | 4 | This is the include file for any module of type base. Base modules only use\r |
5 | types defined via this include file and can be ported easily to any\r | |
959ccb23 | 6 | environment. There are a set of base libraries in the Mde Package that can\r |
7 | be used to implement base modules.\r | |
