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.

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.
