[ANNOUNCE] MCREPOGEN 0.2 released

[Neil Martinsen-Burrell]

MCREPOGEN (http://launchpad.net/mcrepogen), the Markov Chain Repository 
Generator, generates random version control histories with specified 
characteristics.  It uses a Markov Chain model where the states are 
directory trees and various changes to the tree have associated 
probabilities.  The intent is that by giving complete control over the 
characteristics of the history, performance testing of different aspects 
of VCS can be improved.

Download version 0.2 from http://launchpad.net/mcrepogen/+download, 
install with ``easy_install MCREPOGEN``, or pull the latest version with 
``bzr branch lp:mcrepogen``.  MCREPOGEN depends on Bazaar 
(http://bazaar-vcs.org), NumPy (http://numpy.scipy.org) and the 
bzr-fastimport plugin (http://launchpad.net/bzr-fastimport).

After installation, simply ``gen_random_history.py -r 1000 -o 
example.fi`` to generate 1000 random revisions with output in the 
fast-import format.  That output file can then be imported into 
different version control systems, including Bazaar, Mercurial and Git.

Bugs, questions and feedback are welcome at http://launchpad.net/mcrepogen

Changes in version 0.2:
-----------------------

- Add a new configuration file format for specifying transitions and 
their associated parameters.  Using the ``-f`` option, one can specify a 
file in INI-format that lists classes and associated parameter values to 
use in changing the tree.

- Add a number of example configurations to the distribution.

- Use setuptools for distribution

- Fix a bug with exceptions arising from moving a file.  Simply catch 
possible exceptions and skip the move, which is adequate in a 
randomly-evolving tree.
