+The MM library is a 2-layer abstraction library which simplifies the usage
+of shared memory between forked (and this way strongly related) processes
+under Unix platforms. On the first (lower) layer it hides all platform
+dependent implementation details (allocation and locking) when dealing with
+shared memory segments and on the second (higher) layer it provides a
+high-level malloc(3)-style API for a convenient and well known way to work
+with data-structures inside those shared memory segments.
