GLG4sim is derived from the most general parts of KGL4sim, a
Geant4-based Monte Carlo for KamLAND started in 1999 at Tohoku
University by myself (Glenn Horton-Smith) and Haruo Ikeda.
Contributors to KLG4sim between 1999 and 2004 have included, in
alphabetical order, S. Dazeley (Tohoku, LSU), J. Detwiler (Stanford),
G. Horton-Smith (Tohoku, Caltech), L. Hsu (LBL), H. Ikeda (Tohoku),
T. Iwamoto (Tohoku), K. McKinney (Alabama), D. Markoff (TUNL), D. Ray
(LBL), R. Rohm (TUNL), O. Tajima (Tohoku), B. Tipton (Caltech), and
Y. Uchida (Stanford).  It is important to acknowledge their valuable
contributions to KLG4sim.

In creating GLG4sim from KLG4sim, I have removed all KamLAND-specific
features, retaining only features that should be common to all Liquid
scintillator Anti-Neutrino Detector (LAND) simulations.  Since most of
the "boilerplate" infrastructures and the most generic "LAND" features
were implemented by myself, it also turns out I could remove almost
everything I didn't entirely or mostly write myself.  What I could not
remove, nor would I wish to, is the contribution of all KLG4sim
developers and users to exercising and checking the operation of this
code.  Therefore, the people referenced above deserve credit, but I
must accept all blame, for any code found in this initial release of
GLG4sim.

This code is being made available to the neutrino physics community in
the hope it will be useful and in the belief that code of general
interest to the scientific community should be shared freely among
researchers whenever possible.  If any credits or acknowledgments
have been inadvertently omitted, or rights overlooked, I truly regret
such oversight, and welcome notification of correct acknowledgments,
so that details may be rectified in future releases.
