 About
 ###############################################################################
 
-PROJ is a generic coordinate transformation software that transforms geospatial
-coordinates from one coordinate reference system (CRS) to another. This
-includes cartographic projections as well as geodetic transformations.
-
-PROJ includes :ref:`command line applications<apps>` for easy conversion of
-coordinates from text files or directly from user input. In addition to the
-command line utilities PROJ also exposes an
-:ref:`application programming interface<reference>`, or API in short. The API
-lets developers use the functionality of PROJ in their own software without having
-to implement similar functionality themselves.
-
-PROJ started purely as a cartography application letting users convert geodetic
-coordinates into projected coordinates using a number of different cartographic
-projections. Over the years, as the need has become apparent, support for datum
-shifts has slowly worked its way into PROJ as well. Today PROJ supports more
-than a hundred different map projections and can transform coordinates between
-datums using all but the most obscure geodetic techniques.
