- * btree currently doesn't have convenience functions for the simple tasks of
- * "look up by key", "insert a key", and "remove a key". To insert or remove,
- * you first have use btree_find* to position an iterator on the
- * insertion/removal point, then call btree_insert_at or btree_remove_at using
- * that iterator. Since a btree can hold multiple items with the same key,
- * it isn't clear how the convenience functions should work yet. I'm open to
- * suggestions.
