    BVG:  Programs demonstrating Markov chain sampling from a bivariate Gaussian.

    The 'bvg' programs implement sampling from a bivariate Gaussian
    distribution (or several independent replications of a bivariate
    Gaussian), using the Markov chain Monte Carlo package.  This is done
    primarily for testing and demonstration purposes.

    The specification of the bivariate Gaussian distribution is stored in
    the log file as a record of type 'B' and index -1.  The coordinates
    found each iteration are stored in records of type 'X'.  The Markov
    chain Monte Carlo package will of course put various other records in
    the log file as well.
