+Memarea Library
+===============
+
+Introduction
+------------
+
+The memarea library provides an allocator of variable-size objects, it is
+oriented towards the application layer, providing 'region-based memory
+management' function [1].
+
+The main features are as follows:
+
+* The memory region can be initialized from the following memory sources:
+
+  - HEAP: e.g. invoke ``rte_malloc_socket``.
+
+  - LIBC: e.g. invoke posix_memalign.
+
+  - Another memarea: it can be allocated from another memarea.
+
+* It supports MT-safe as long as it's specified at creation time.
+
+* The address returned by the allocator is align to 8B.
+
+Library API Overview
+--------------------
+
+The ``rte_memarea_create()`` function is used to create a memarea, the function
+returns the pointer to the created memarea or ``NULL`` if the creation failed.
+
+The ``rte_memarea_destroy()`` function is used to destroy a memarea.
+
+Debug Mode
+----------
+
+In debug mode, cookies are added at the beginning and end of objects, it will
+help debugging buffer overflows.
+
+Debug mode is disabled by default, but can be enabled by setting
+``RTE_LIBRTE_MEMAREA_DEBUG`` in ``config/rte_config.h``.
