-== New Hierarchical Clustering module ==
-This module adds new hierarchical clustering functionality to the
-cluster package. Its interface is similar to the hierarchical
-clustering functions provided in MATLAB(TM)'s Statistics Toolbox to
-facilitate easier migration to the NumPy/SciPy framework. Linkage
-methods implemented include single, complete, average, weighted,
-centroid, median, and ward. Several functions are provided for
-computing statistics on clusters including inconsistency statistics,
-cophenetic distance, and maximum distance of descendants. The fcluster
-and fclusterdata functions take hierarchical tree clusterings
-generated by these algorithms, cuts the tree, and labels the flat
-clusters. The leaders function finds the root of each flat cluster
-given a hierarchical clustering and labellings of its leaves. Finally, a
-matplotlib extension is provided for plotting dendrograms, which
-may be outputted to postscript or any other supported format.

+Collection of spatial algorithms and data structures useful for spatial

+kd-tree with the same interface but that supports annotation and a variety
+of other algorithms. The API for both modules may change somewhat as user

Includes fast compiled code for computing exact and approximate nearest neighbors, as well as a pure-python kd-tree with the same interface but that supports annotation and a variety of other algorithms. The API for both modules may change somewhat as user requirements become clearer. Also includes a submodule "distance" containing fast code for many definitions of "distance" between vectors. Distance and dissimilarity functions are provided include Bray-Curtis, Canberra, Chebyshev, City Block, Cosine, Dice, Euclidean, Hamming, Jaccard, Kulsinski, Mahalanobis, Matching, Minkowski, Rogers-Tanimoto, Russell-Rao, Squared Euclidean, Standardized Euclidean, Sokal-Michener, Sokal-Sneath, and Yule. Two functions are provided for computing distances between collections of vectors: pdist and cdist. pdist is similar to the MATLAB(TM) function and computes pairwise distances between a collection of vectors. cdist computes distances between vectors in two sets of vectors. squareform converts between square distance matrices and condensed distance matrices.

 FFTW2, FFTW3, MKL and DJBFFT wrappers have been removed. Only (NETLIB)
 fftpack remains. By focusing on one backend, we hope to add new
 features -- like float32 support -- more easily.
