+ * Guarded memory (de)allocation
+ *
+ *
+ * @mainpage MEM - c-style guarded memory allocation
+ *
+ * @section about About the MEM module
+ *
+ * MEM provides guarded malloc/calloc calls. All memory is enclosed by
+ * pads, to detect out-of-bound writes. All blocks are placed in a
+ * linked list, so they remain reachable at all times. There is no
+ * back-up in case the linked-list related data is lost.
+ *
+ * @section issues Known issues with MEM
+ *
+ * There are currently no known issues with MEM. Note that there is a
+ * second intern/ module with MEM_ prefix, for use in c++.
+ * 
+ * @section dependencies Dependencies
+ *
+ * - stdlib
+ *
+ * - stdio
