%description
Allows one to estimate the output of a computer program, as a function of
the input parameters, without actually running it. The computer program is
assumed to be a Gaussian process, whose parameters are estimated using
Bayesian techniques that give a PDF of expected program output.  This PDF
is conditional on a training set of runs, each consisting of a point in
parameter space and the model output at that point.  The emphasis is on
complex codes that take weeks or months to run, and that have a large
number of undetermined input parameters; many climate prediction models
fall into this class.  The emulator essentially determines Bayesian
posterior estimates of the PDF of the output of a model, conditioned on
results from previous runs and a user-specified prior linear model.  The
package includes functionality to evaluate quadratic forms efficiently.
