+packages for fitting Bayesian models or working with output from Bayesian
+models.  The primary goals of the package are to:
+
+@enumerate
+@item Efficiently convert between many different useful formats of
+draws (samples) from posterior or prior distributions.
+
+@item Provide consistent methods for operations commonly performed on draws,
+for example, subsetting, binding, or mutating draws.
+
+@item Provide various summaries of draws in convenient formats.
+
+@item Provide lightweight implementations of state of the art posterior
+inference diagnostics.
