  abstract =     {This is the user's manual for DEGAS 2—a Monte
                  Carlo code for the study of neutral atom and molecular
                  transport in confined plasmas.  It is intended to
                  cover all aspects of DEGAS 2 from the user's
                  point-of-view: obtaining the files, compiling them,
                  setting up the input files, executing the code, and
                  interpreting the output.  References will be provided
                  for the underlying physics, but the essential aspects
                  will be highlighted.  Information for programmers
                  interested in modifying DEGAS 2 can be found within
                  the source code itself.  Links to some of the more
                  useful ones are provided.}
