[BioPython] Biopython 1.23 available

[Jeffrey Chang]

Hello Everybody,

Biopython 1.23 is now available from the website at:
http://www.biopython.org/

This is mostly a maintenance release, which fixes some problems in the 
installation.  You do not need to update from 1.22 unless you are using 
the Bio.Cluster, Bio.KDTree, or Bio.PDB.mmCIF packages.  The changes 
made in this release are:
   Fixed distribution of files in Bio/Cluster
   Now distributing Bio/KDTree/_KDTree.swig.C
   minor updates in installation code
   added mmCIF support for PDB files

As usual, please report bugs to biopython-dev at biopython.org, or the bug 
database also available from the website.

Jeff
