+===============
+
+Internal VPP memory allocations rely on VPP main-heap, however when
+using external libraries, esp. in plugins (e.g. OpenSSL library used by
+the IKEv2 plugin), those external libraries usually manages memory using
+the standard libc ``malloc()``/``free()``/… calls. This, in turn, makes
+use of the default libc heap.

+VPP has no knowledge of this heap and tools such as memory traces cannot

+In order to enable the use of standard VPP debugging tools, this library
+replaces standard libc memory management calls with version using VPP
+main-heap.

+To use it, you need to use the ``LD_PRELOAD`` mechanism, e.g.
