Additional information on these papers can be found here. SOAR is distributed as ANSI/ISO C89 source code and should compile under Unix and Windows using most compliant C compilers (note that MSVC by default does NOT compile in ANSI/ISO mode). You may download and install this software freely, but please read this distribution and licensing information first. Further information on running SOAR and building data sets is contained in this README file and the SOAR FAQ. See the VERSIONS file for a history of changes to SOAR. Please report bugs and installation problems to pl@llnl.gov.

Downloads
The source code is available as a gzipped tar archive (for Unix/Linux users) and as a WinZip zip file (for Windows users). For problems installing or running SOAR, please see our FAQ or send us an e-mail describing your problem. In particular, if you're using MSVC, please follow the installation instructions carefully.
