You can adapt this file completely to your liking, but it should at least
contain the root `toctree` directive.
Chroma: Ultra-fast Photon Monte Carlo
=====================================
Chroma is a high performance optical photon simulation for particle physics detectors. It tracks individual photons passing through a triangle-mesh detector geometry, simulating standard physics processes like diffuse and specular reflections, refraction, Rayleigh scattering and absorption.
With the assistance of a CUDA-enabled GPU, Chroma can propagate 2.5 million photons per second in a detector with 29,000 photomultiplier tubes. This is 200x faster than the same simulation with GEANT4.
Development
-----------
Chroma is under heavy development. Tagged releases will happen soon,
but in the meantime we encourage people to obtain the code directly
from the Mercurial repository hosted at Bitbucket:
http://bitbucket.org/chroma/chroma
For questions, ideas, and discussion, join the Chroma development mailing list:
http://groups.google.com/group/chroma-sim
For bug reports, please create a Bitbucket account and use the Bitbucket issue tracker:
https://bitbucket.org/chroma/chroma/issues?status=new&status=open
Documentation
-------------
The core concepts are described in the :download:`Chroma whitepaper
<chroma.pdf>`.
The software documentation is evolving rapidly, so
many of the following sections are incomplete at the moment.

Authors
-------
Chroma is developed by Anthony LaTorre and `Stan Seibert
<mailto:sseibert@hep.upenn.edu>`_. Chroma contains some material
properties found in the `WCSim application
<https://wiki.bnl.gov/dusel/index.php/WCSim>`_.
