+//----------------------------------------------------------------
+// Statically-allocated memory manager

+//
+// Memory manager: dynamically allocates memory from
+// a fixed pool that is allocated statically at link-time.
+//
+// Usage: after calling memmgr_init() in your
+// initialization routine, just use memmgr_alloc() instead
+// of malloc() and memmgr_free() instead of free().
+// Naturally, you can use the preprocessor to define
+// malloc() and free() as aliases to memmgr_alloc() and
+// memmgr_free(). This way the manager will be a drop-in
+// replacement for the standard C library allocators, and can
+// be useful for debugging memory allocation problems and
+// leaks.
+//
+// Preprocessor flags you can define to customize the
+// memory manager:
+//
+// DEBUG_MEMMGR_FATAL
+// Allow printing out a message when allocations fail
+//
+// DEBUG_MEMMGR_SUPPORT_STATS
+// Allow printing out of stats in function
+// memmgr_print_stats When this is disabled,
+// memmgr_print_stats does nothing.
+//
+// Note that in production code on an embedded system
+// you'll probably want to keep those undefined, because
+// they cause printf to be called.
+//
+// POOL_SIZE
+// Size of the pool for new allocations. This is
+// effectively the heap size of the application, and can
+// be changed in accordance with the available memory
+// resources.
+//
+// MIN_POOL_ALLOC_QUANTAS
+// Internally, the memory manager allocates memory in
+// quantas roughly the size of two ulong objects. To
+// minimize pool fragmentation in case of multiple allocations
+// and deallocations, it is advisable to not allocate
+// blocks that are too small.
+// This flag sets the minimal ammount of quantas for
+// an allocation. If the size of a ulong is 4 and you
+// set this flag to 16, the minimal size of an allocation
+// will be 4 * 2 * 16 = 128 bytes
+// If you have a lot of small allocations, keep this value
+// low to conserve memory. If you have mostly large
+// allocations, it is best to make it higher, to avoid
+// fragmentation.
+//
+// Notes:
+// 1. This memory manager is *not thread safe*. Use it only
+// for single thread/task applications.
