+Profiling is done with tiny-profiler, a very simple profiler.
+
+It is different from python's built-in profilers in that it requires
+developpers to explicitely put probes on specific methods, reducing:
+- profiling overhead
+- undesired result entries
+
+You can get this profiler at:
+  https://svn.erp5.org/repos/public/erp5/trunk/utils/tiny_profiler
