+ (description
+ "@code{fgivenx} is a Python package for plotting posteriors of functions.
+It is currently used in astronomy, but will be of use to any scientists
+performing Bayesian analyses which have predictive posteriors that are
+functions.
+
+This package allows one to plot a predictive posterior of a function,
+dependent on sampled parameters. It assumes one has a Bayesian posterior
+@code{Post(theta|D,M)} described by a set of posterior samples
+@code{{theta_i}~Post}. If there is a function parameterised by theta
+@code{y=f(x;theta)}, then this script will produce a contour plot of the
+conditional posterior @code{P(y|x,D,M)} in the @code{(x,y)} plane.")
