The configuration of the @PLUGIN@ plugin is done in the gerrit.config
file.
[plugin "@PLUGIN@"] jail = Confidential-Projects protectorate = Public-Projects
Child projects can only be reparented within the subtree of this project. E.g. parent projects that define mandatory block rules should be defined as 'jail' projects so that their child projects cannot escape the block rules by reparenting. The `jail` option can be specified multiple times. This restriction does not apply to Gerrit administrators.
Non-Child projects cannot be reparented under the subtree of this project. E.g. parent projects that define a group of projects for which a certain process applies (e.g they are released together) can be defined as 'protectorate' projects, so that only administrators can reparent new projects under it. The `protectorate` option can be specified multiple times. This restriction does not apply to Gerrit administrators.
