+Compute expected shortfall (ES) and Value at Risk (VaR) from a quantile
+function, distribution function, random number generator or probability density
+function. ES is also known as Conditional Value at Risk (CVaR). Virtually any
+continuous distribution can be specified. The functions are vectorized over the
+arguments. The computations are done directly from the definitions, see e.g.
+Acerbi and Tasche (2002) <doi:10.1111/1468-0300.00091>. Some support for GARCH
+models is provided, as well.
