%description
A wrapper around the generic coordinate transformation software 'PROJ'
that transforms coordinates from one coordinate reference system ('CRS')
to another. This includes cartographic projections as well as geodetic
transformations.  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.
