%description
A variety of functions for the best known and most innovative approaches
to nonparametric boundary estimation. The selected methods are concerned
with empirical, smoothed, unrestricted as well as constrained fits under
both separate and multiple shape constraints. They cover robust approaches
to outliers as well as data envelopment techniques based on piecewise
polynomials, splines, local linear fitting, extreme values and kernel
smoothing. The package also seamlessly allows for Monte Carlo comparisons
among these different estimation methods.  Its use is illustrated via a
number of empirical applications and simulated examples.
