- * @summary
+ * @brief
  *  Trouts list all uses of types and entities.
  *  Each type gets a list of all Alloc nodes allocating it.
  *  Each entity gets two lists:
  *    - one containing all accesses (Load, (Call), Store),
  *    - and one containing all uses to get a reference (Sel, SymConst).
- *
- * @todo
- *   To list all uses of entities of a type, we also should list all
- *   static/automatic allocated entities in types.  The Alloc nodes
- *   represent only the dynamic allocated entities.
