Alembic uses configparser to parse its config files, which is
compatible with the paste.deploy ini config files in terms of
encoding, but paste.deploy has additional features such as
user = config:
lines. This reduces the amount of places thatalembic config files are generated throughout the codebase and
uses paste.deploy to extract the config values for the
app:conduit
section before directly inserting them into an alembic config.
This allows users to omit
script_location
from test.ini, and moreoverto omit any parameters required by alembic that are set in a parent
of the relevant app:conduit block.
