+# This is a test application for PyQt5. It is showing a text label and
+# a "quit" button. The text of the label can be set with the first
+# (non-Qt) command line argument. A timer will send a click signal to
+# the quit button after 3 seconds. When quitting, the text of the
+# label is saved in a "message.txt" file in the current working
+# directory.
