This overlay can be used whenever we need to override
|
|
dependencies specific to the mailman ecosystem: in the past
|
|
this was necessary for e.g. psycopg2[1] or sqlalchemy[2].
|
|
|
|
In such a large ecosystem this sort of issue is expected
|
|
to arise again. Since we don't want to clutter the python package-set
|
|
itself with version overrides and don't want to change the APIs
|
|
in here back and forth every time this comes up (and as a result
|
|
force users to change their code accordingly), this empty overlay
|
|
is kept on purpose.
