+"""
+Change a storage for a project
+
+Copr supports different storage solutions for repositories with the built RPM
+packages (e.g. results directory on copr-backend or Pulp). This script allows to
+configure the storage type for a given project and while doing so, it makes sure
+DNF repositories for the project are created.
+
+Existing builds are not migrated from one storage to another. This may be an
+useful feature but it is not implemented yet.
