+    (description
+     "@code{go-datastructures} is a collection of useful, performant, and
+thread-safe Go data structures.
+
+It includes:
+@itemize
+@item Augmented Tree - Interval tree for collision in n-dimensional
+ranges.  Implemented via a red-black augmented tree.
+
+@item Bitarray - Bitarray used to detect existence without having to resort to
+hashing with hashmaps.  Requires entities have a uint64 unique identifier.  Two
+implementations exist, regular and sparse.
+
+@item Futures - A helpful tool to send a @emph{broadcast} message to
+listeners.
+
+@item Queue - Package contains both a normal and priority queue.  Both
+implementations never block on send and grow as much as necessary.
+
+@item Fibonacci Heap - A standard Fibonacci heap providing the usual
+operations.  Can be useful in executing Dijkstra or Prim's algorithms in the
+theoretically minimal time.
+
+@item Range Tree - Useful to determine if n-dimensional points fall within an
+n-dimensional range.
+
+@item Set - Set implementation which accepts items of type @code{interface{}}
+and includes only a few methods.
+
+@item Threadsafe - A package that is meant to contain some commonly used items
+but in a threadsafe way.
+
+@item AVL Tree - This is an example of a branch copy immutable
+@acronym{Adelson-Velsky and Landis,AVL} @acronym{Balanced Binary Search
+Trees,BBST}.
+
+@item X-Fast Trie - An interesting design that treats integers as words and
+uses a trie structure to reduce time complexities by matching prefixes.
+
+@item Y-Fast Trie - An extension of the X-Fast trie in which an X-Fast trie is
+combined with some other ordered data structure to reduce space consumption
+and improve CRUD types of operations.
+
+@item Fast Integer Hashmap - A datastructure used for checking existence but
+without knowing the bounds of your data.  If you have a limited small bounds,
+the bitarray package might be a better choice.
+
+@item Skiplist - An ordered structure that provides amortized logarithmic
+operations but without the complication of rotations that are required by
+BSTs.
+
+@item Sort - The sort package implements a multithreaded bucket sort that can
+be up to 3x faster than the native Golang sort package.
+
+@item Numerics - Early work on some nonlinear optimization problems.  The
+initial implementation allows a simple use case with either linear or
+nonlinear constraints.
+
+@item B+ Tree - Initial implementation of a B+ tree.  Delete method still
+needs added as well as some performance optimization.
+
+@item Immutable B Tree - A btree based on two principles, immutability and
+concurrency.
+
+@item Ctrie - A concurrent, lock-free hash array mapped trie with efficient
+non-blocking snapshots.
+
+@item Dtrie - A persistent hash trie that dynamically expands or shrinks to
+provide efficient memory allocation.
+
+@item Persistent List - A persistent, immutable linked list.
+
+@item Simple Graph - A mutable, non-persistent undirected graph where parallel
+edges and self-loops are not permitted.
