+allow-uninst `<action list>`
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When trying migration of items, don't consider the uninstallability of binary
+packages in the `<action list>`. This means that items can still migrate if
+they cause these packages to become uninstallable.
+
+The `<action list>` is a list of unversioned binary packages. If an
+architecture is specified, it only applies to the specific architecture.
+Please note that the specified architecture is the architecture where Britney
+does the installability test. For arch: all package, this means that all
+relevant (`nobreakall`) architectures need to be specified, not `all`.
