+    Here we create another new directory and save a reference so we can later access the node

     but it works like this anyways and it's an implementation detail that must not concern you
     here).

-    This will automatically remove the node from the tree when the senf::console::ScopedDiretory

-    and is the preferred way to keep a hold on a directory.
+    This will automatically remove the node from the tree when the \c senf::console::ScopedDirectory
+    instance is destroyed. It also protects against the problem of dangling references: When using a
+    plain reference, removing the directory from the tree will destroy the node. The reference
+    however will still reference the (now nonexistent) directory and any access via the reference
+    will crash the program.
