The current package is called CSWpy-sqlalchemy with version 0.8.3, should I make a
CSWpy-sqlalchemy-buildbot with the required 0.7.10 and make that incompatible with
CSWpy-sqlalchemy? That would mean two packages with different version and different
names and incompatible versions, but the same upstream contents in different versions.
It would also mean you can't install all packages of the catalog. Right?


Best regards
