+"""Tests for the ipdoctest machinery itself.
+
+Note: in a file named test_X, functions whose only test is their docstring (as
+a doctest) and which have no test functionality of their own, should be called
+'doctest_foo' instead of 'test_foo', otherwise they get double-counted (the
+empty function call is counted as a test, which just inflates tests numbers
+artificially).
