+@code{dist} function to calculate distance matrices for continuous, binary,
+and multi-dimensional input matrices, which supports a broad variety of
+predefined distance functions from other R packages, as well as user- defined
+functions written in C++.  For ease of use, the @code{parDist} function
+extends the signature of the @code{dist} function and uses the same parameter
+naming conventions as distance methods of existing R packages.")
