In our environment, we needed to create and drop replication over and over in our test environment and I got really tired of having to manually go to each table with an identity column to set its ranges. This stored procedure will create or drop the publications and/or subscriptions for all or some of the objects in your database. Its nothing fancy, and could use a lot of tweaking for your needs, but it works well for us.
