+
+    rad watch -r <ref> [-t <oid>] [--repo <rid>] [<option>...]
+
+    Watches a Git reference, and optionally exits when it reaches a target value.
+    If no target value is passed, exits when the target changes.
+
+Options
+
+        --repo      <rid>       The repository to watch (default: `rad .`)

+    -r, --ref       <ref>       The fully-qualified Git reference (branch, tag, etc.) to watch,
+                                eg. 'refs/heads/master'
+    -t, --target    <oid>       The target OID (commit hash) that when reached,
+                                will cause the command to exit
+    -i, --interval  <millis>    How often, in milliseconds, to check the reference target
+                                (default: 1000)
