+ * @brief The mallocator system
+ *
+ * This section describes the API to a mallocator.
+ * A mallocator allows you to recycle the objects you don't need anymore instead of freeing them. A mallocator is a
+ * stack which stores the unused objects or a given type. If you often need to malloc() / free() objects of a certain
+ * type, you should use a mallocator and call @a xbt_mallocator_get() and @a xbt_mallocator_release() instead of
+ * malloc() and free().
+ *
+ * When you release an object, it is not freed but it is stored into the mallocator (unless the mallocator is full).
+ * And when you want to get a new object, the object is just extracted from the mallocator. No malloc() is done,
+ * unless there is no more object in the mallocator.
