Hi all,

Here is a summary of the new BW G4 simulation from Monday's meeting:

The main simulation package for Braidwood will be Reactor Analysis Tool
(RAT). The available RAT documentation is here:

http://www.hep.utexas.edu/sno/bw/

As a subdirectory of the RAT package we will keep a release of the
Geant4-based Monte Carlo GLG4sim. GLG4sim will be used as a library to
generate Monte Carlo events. However, RAT will be able to process data
events as well. Keeping GLG4sim inside the RAT release, rather than a
separate package, will ensure that each tagged version of RAT will have
its "own" version of GLG4sim known to work with that RAT code.

All Braidwood-specific code will be kept in RAT. This includes any code
that overloads classes in GLG4sim. Any changes to the GLG4sim source code
will be made available to the GLG4sim maintainers for possible inclusion
in their own release. As GLG4sim improves, we will update the
Braidwood-maintained version in the RAT release to match the current
GLG4sim release. This will be done only after significant testing, to
ensure that users only have stable GLG4sim code and do not have to treat
GLG4sim as "development" code.

Prebuilt libraries for GLG4sim will not be distributed, rather the make
command in RAT will include a configuration and build of the GLG4sim
libraries for users' systems. The BWsim package in the CVS repository will
be discontinued.
