- --at - specify what repostory to use
- --dry-run - just what would be done if the command actually executed
- --http-proxy - specify the local http proxy
- --only - limit what files are updated
- --timeout - limit how long the update can execute before it will be terminated
- -v - verbose output (note that the single dash is correct here)
