+Introduction
+============
+
+The **c-rbtree** project provides a Red-Black-Tree API, that is fully
+implemented in ISO-C11 and has no external dependencies. Furthermore, tree
+traversal, memory allocations, and key comparisons are completely controlled by
+the API user. The implementation only provides the RB-Tree specific rebalancing
+and coloring.
