Commit Message

Markus Armbruster Oct. 10, 2020, 9:54 a.m. UTC 
From: John Snow <jsnow@redhat.com>

At this point, that just means using a consistent strategy for constant names.
constants get UPPER_CASE and names not used externally get a leading underscore.

As a preference, while renaming constants to be UPPERCASE, move them to
the head of the file. Generally, it's nice to be able to audit the code
that runs on import in one central place.
