                        HARM  version 1.0   (released May 1, 2006)

    This file is part of HARM.  HARM is a program that solves hyperbolic 
    partial differential equations in conservative form using high-resolution
    shock-capturing techniques.  This version of HARM has been configured to 
    solve the relativistic magnetohydrodynamic equations of motion on a 
    stationary black hole spacetime in Kerr-Schild coordinates to evolve
    an accretion disk model. 

    You are morally obligated to cite the following two papers in his/her 
    scientific literature that results from use of any part of HARM:

    [1] Gammie, C. F., McKinney, J. C., \& Toth, G.\ 2003, 
        Astrophysical Journal, 589, 444.

    [2] Noble, S. C., Gammie, C. F., McKinney, J. C., \& Del Zanna, L. \ 2006,

    HARM directly from our distribution website:
