+"""Tests build_font.py by renaming a font.
+
+The test copies Roboto-Regular.ttf to a tmp directory and ask build_font.py to rename it and put in another dir.
+We then use ttx to dump the new font to its xml and check if rename was successful
+
+To test locally, use:
+PYTHONPATH="$PYTHONPATH:/path/to/android/checkout/external/fonttools/Lib" ./test.py
