+# Then the script runs every executable *.py script anywhere in the copied dir,
+# the working directory temporarily changed to where the *.py file is.
+# Proper virtualenv is assumed to be active.
+# Then another directory in ${GENERATED_DIR} is created, where

+# The diff output is stored to autogen.log (overwriting).
