+=================================
+Counted inline doubly-linked list
+=================================
+
+clist is the inline doubly-linked list cousin of the inline doubly-linked list,
+extended by a counter to retrieve the number of elements in the list in O(1)
+time. This is also why all operations always require the list head. For
+traversal of clists, use the corresponding HXlist macros.
+
+Synopsis
+========
+
+.. code-block:: c
+
+	#include <libHX/list.h>
+
+	struct HXclist_head {
+		/* public readonly: */
+		unsigned int items;
+		/* Undocumented fields are considered “private” */
+	};
+
+	HXCLIST_HEAD_INIT(name);
+	HXCLIST_HEAD(name);
+	void HXclist_init(struct HXclist_head *head);
+	void HXclist_unshift(struct HXclist_head *head, struct HXlist_head *new_node);
+	void HXclist_push(struct HXclist_head *head, struct HXlist_head *new_node);
+	type HXclist_pop(struct HXclist_head *head, type, member);
+	type HXclist_shift(struct HXclist_head *head, type, member);
+	void HXclist_del(struct HXclist_head *head, struct HXlist_chead *node);
+
+``HXCLIST_HEAD_INIT``
+	Macro that expands to the static initializer for a clist.
+
+``HXCLIST_HEAD``
+	Macro that expands to the definition of a clist head, with
+	initialization.
+
+``HXclist_init``
+	Initializes a clist. This function is generally used when the head has
+	been allocated from the heap.
+
+``HXclist_unshift``
+	Adds the node to the front of the list.
+
+``HXclist_push``
+	Adds the node to the end of the list.
+
+``HXclist_pop``
+	Removes the last node in the list and returns it.
+
+``HXclist_shift``
+	Removes the first node in the list and returns it.
+
+``HXclist_del``
+	Deletes the node from the list.
+
+The list count in the clist head is updated whenever a modification is done on
+the clist through these functions.
