+# This is a modified version of Qt5LinguistToolsMacros.cmake which calls
+# pylupdate5 instead of lupdate, allowing Python strings to be extracted,
+# too. It still requires the Qt version of the file to be included, but
+# only this version of the function needs to be called. You also need to
+# have PYTHON_ROOT set to a directory where a working pylupdate5.bat can
+# be found. If you aren't using Windows, your platform's equivalent may
+# work, too.
