%description
Simple trustworthy utility functions to use TauDEM (Terrain Analysis Using
Digital Elevation Models <https://hydrology.usu.edu/taudem/taudem5/>)
command-line interface. This package provides a guide to installation of
TauDEM and its dependencies GDAL (Geopatial Data Abstraction Library) and
MPI (Message Passing Interface) for different operating systems. Moreover,
it checks that TauDEM and its dependencies are correctly installed and
included to the PATH, and it provides wrapper commands for calling TauDEM
methods from R.
