+GDAL is a library for reading and writing raster geospatial data
+formats, and is released under an X/MIT style Open Source license by
+the Open Source Geospatial Foundation. As a library, it presents a
+single abstract data model to the calling application for all
+supported formats. It may also be built with a variety of useful
+command-line utilities for data translation and processing.
+The related OGR library (which is part of the GDAL source tree)
+provides a similar capability for simple features vector data.
+The following optional requirements are detected automatically:
+cfitsio, freexl, hdf5, libwebp, netcdf, postgresql, xerces-c
+To enable OpenCL GPU-accelerated performance, specify the option
+OPENCL=yes (requires opencl-headers to build, and either nvidia-driver
+or amd-app-sdk with suitable GPU hardware to run).
