System for Automated Geoscientific Analyses (SAGA) is a Geographic Information
System software with immense capabilities for geodata processing and analysis.

SAGA supports the implementation of new functions with an effective API.
Functions are organised as modules in framework independent Module Libraries
and can be accessed via SAGA's Graphical User Interface or various scripting
environments (shell scripts, Python, R and so on).

SAGA can use these optional dependencies: libharu, postgresql and qhull. SAGA
currently does not build when vigra is installed.

To enable opencv, set OPENCV=ON. By default OpenCV is disabled since SAGA does
not build when opencv version 4 or greater is installed. For a compatible
version of OpenCV, use the opencv-legacy SlackBuild.

If SAGA fails to run after an upgrade, uninstall old versions of SAGA before
compilation.
