+ (description
+ "This package provides a fast parallelized alternative to R's native
+'dist' function to calculate distance matrices for continuous, binary, and
+multi-dimensional input matrices, which supports a broad variety of 41
+predefined distance functions from the 'stats', 'proxy' and 'dtw' R packages,
+as well as user- defined functions written in C++. For ease of use, the
+'parDist' function extends the signature of the 'dist' function and uses the
+same parameter naming conventions as distance methods of existing R packages.
+The package is mainly implemented in C++ and leverages the 'RcppParallel'
+package to parallelize the distance computations with the help of the
+'TinyThread' library. Furthermore, the 'Armadillo' linear algebra library is
+used for optimized matrix operations during distance calculations. The
+curiously recurring template pattern (CRTP) technique is applied to avoid
+virtual functions, which improves the Dynamic Time Warping calculations while
+the implementation stays flexible enough to support different DTW step
+patterns and normalization methods.")
