In addition to a physics survey, the current report also contains a complete manual for the program. Such manuals have always been updated and distributed jointly with the programs, but have grown in size with time. A word of warning may therefore be in place. The program description is fairly lengthy, and certainly could not be absorbed in one sitting. This is not even necessary, since all switches and parameters are provided with sensible default values, based on our best understanding (of the physics, and of what you expect to happen if you do not specify any options). As a new user, you can therefore disregard all the fancy options, and just run the program with a minimum ado. Later on, as you gain experience, the options that seem useful can be tried out. No single user is ever likely to find need for more than a fraction of the total number of possibilities available, yet many of them have been added to meet specific user requests.
In some instances, not even this report will provide you with all the
information you desire. You may wish to find out about recent versions
of the program, know about related software, pick up a few sample
main programs to get going, or get hold of related physics papers.
