+# This is a valgrind suppression file that should be used when using valgrind.
+#
+#  Here's an example of running valgrind:
+#
+#	cd python/dist/src
+#	valgrind --tool=memcheck --suppressions=Misc/valgrind-python.supp \
+#		./python -E -tt ./Lib/test/regrtest.py -u bsddb,network
+#
+# You must edit Objects/obmalloc.c and uncomment Py_USING_MEMORY_DEBUGGER
+# to use the preferred suppressions with Py_ADDRESS_IN_RANGE.
+#
+# If you do not want to recompile Python, you can uncomment
+# suppressions for PyObject_Free and PyObject_Realloc. [ => DONE BY SJO ]
+#
+# See Misc/README.valgrind for more information.
+
+# all tool names: Addrcheck,Memcheck,cachegrind,helgrind,massif
