// Purpose:       Provides an interface to create and destroy memory

//                regions and sections within the memory map. Exposes

//                data structures for the presentation of this data

//                by external code.

// Known bugs:    <UPDATE_ME_AT_RELEASE_TIME>

// WARNING:       Do not modify data structures other than by using the

//                provided functions

// Usage:         #include "memmap.h"
