-Subject: [PATCH] Fix deprecation warning in Python 3.7 (#231)
-
-$SITE_PYTHON/lib/python3.7/site-packages/elftools/construct/lib/container.py:5
- Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working
-
-This change is compatible with Python 3.3 and up, when the ABCs were
-moved to collections.abc. Backward compatibility is retained through
-the try/except block.
