A wrapper around the generic coordinate transformation software 'PROJ'
that transforms geospatial coordinates from one coordinate reference system ('CRS')
to another. This includes cartographic projections as well as geodetic transformations.
Version 7.1.0-1 or higher of the R package 'libproj' is required. The intention is for this
package to be used by user-packages such as 'reproj', and that the older 'PROJ.4' and version 5
pathways be provided by the 'proj4' package. Separating this disruptive version
change (from 4.0 and 5.0, to 6.0 and above) allows the use of existing and
stable code in 'proj4' alongside the new idioms and requirements of modern 'PROJ'. For control
of metadata files for the 'PROJ' library, see tools in the 'libproj' package.
Michael D. Sumner [aut, cre] (<https://orcid.org/0000-0002-2471-7511>),
Jeroen Ooms [ctb] (provided PROJ library support on Windows, and
assistance with Windows configuration),
Simon Urbanek [cph, ctb] (wrote original code versions for PROJ version
6),
Dewey Dunnington [ctb] (key code contributions, and provided libproj to
improve things a lot)

Currently non-operational, a harmless wrapper to allow package 'reproj' to install and
function while relying on the 'proj4' package.
