+/*
+ * The purpose of this header is to define the macros ALLOCATE_LOCAL and
+ * DEALLOCATE_LOCAL appropriately for the platform being compiled on.
+ * These macros are used to make fast, function-local memory allocations.
+ * Their characteristics are as follows:
+ *
+ * void *ALLOCATE_LOCAL(int size)
+ *    Returns a pointer to size bytes of memory, or NULL if the allocation
+ *    failed.  The memory must be freed with DEALLOCATE_LOCAL before the
+ *    function that made the allocation returns.  You should not ask for
+ *    large blocks of memory with this function, since on many platforms
+ *    the memory comes from the stack, which may have limited size.
+ *
+ * void DEALLOCATE_LOCAL(void *)
+ *    Frees the memory allocated by ALLOCATE_LOCAL.  Omission of this
+ *    step may be harmless on some platforms, but will result in
+ *    memory leaks or worse on others.
+ *
+ * Before including this file, you should define two macros,
+ * ALLOCATE_LOCAL_FALLBACK and DEALLOCATE_LOCAL_FALLBACK, that have the
+ * same characteristics as ALLOCATE_LOCAL and DEALLOCATE_LOCAL.  The
+ * header uses the fallbacks if it doesn't know a "better" way to define
+ * ALLOCATE_LOCAL and DEALLOCATE_LOCAL.  Typical usage would be:
+ *
+ *    #define ALLOCATE_LOCAL_FALLBACK(_size) malloc(_size)
+ *    #define DEALLOCATE_LOCAL_FALLBACK(_ptr) free(_ptr)
+ *    #include "Xalloca.h"
