+/**
+ * \class DList
+ * \brief Basic doubly linked list.
+ *
+ * DList is the standard by-structure list type. This class requires the
+ * programmer to declare a list element type that has the necessary next and
+ * previous pointers in it. This can be achieved by inheriting from the
+ * DListEl class or by simply adding next and previous pointers directly into
+ * the list element class.
+ *
+ * DList does not assume ownership of elements in the list. If the elements
+ * are known to reside on the heap, the provided empty() routine can be used to
+ * delete all elements, however the destructor will not call this routine, it
+ * will simply abandon all the elements. It is up to the programmer to
+ * explicitly de-allocate items when necessary.
+ *
