+- `remove` to remove a linked worktree and its administrative files (and
+  warn if the worktree is dirty)
+- `mv` to move or rename a worktree and update its administrative files
+- `list` to list linked worktrees
+- `lock` to prevent automatic pruning of administrative files (for instance,
+  for a worktree on a portable device)
