| """Page and form handlers for project administration "advanced" subtab. |

| The advanced subtab allows the project to be archived, unarchived, deleted, or |
| marked as moved. Site admins can use this page to "doom" a project, which is |
| basically archiving it in a way that cannot be reversed by the project owners. |
| |
| The page also shows project data storage quota and usage values, and |
| site admins can edit those quotas. |
