-OpenCV (Open Source Computer Vision)
+OpenCV (Open Source Computer Vision Library) is an open source
+computer vision and machine learning software library.
+OpenCV was built to provide a common infrastructure for
+computer vision applications and to accelerate the use of
+machine perception in commercial products.
 
-OpenCV is a library of programming functions mainly
-aimed at real-time computer vision.
+OpenCV will incorporate features from a wide range of additional
+software that may exist on the host system at build time. The more
+of the relevant software packages that are available, the greater
+the feature set available in the resulting OpenCV package. The
+additional optional packages will mostly be autodetected and used
+at build time without any user intervention. Packages that are
+processed in this way include (by SBo package name):
+    qt5 libdc1394 ffmpeg hdf5 VTK jdk apache-ant numpy python3 numpy3
 
-numpy (for the python bindings), ffmpeg and qt5 are
-optional dependencies.
+In the unlikely situation that features from these packages are not
+wanted despite already being installed on the host system,
+incorporation of some of them into OpenCV may be suppressed by setting
+the appropriate environment variable to "no" e.g.
+    CVFFMPEG=no ./opencv.SlackBuild
+Features that may be excluded in this manner are controlled by the
+following environment variables:
+    CV1394 CVFFMPEG CVVTK
+
+At least one optional package is not autodetected, even though the
+necessary prerequisite software may already have been installed. It
+must therefore be explicitly enabled by setting the appropriate
+environment variable:
+    CVGDAL=yes ./opencv.SlackBuild
+(to support SBo's gis/gdal)
+
+Please note that some combinations of options may not be possible. In
+particular, if both qt5 and VTK are installed on the host build system,
+VTK support will be disabled unless it was built with qt5 support (which
+is possible but not its default). Conversely, if VTK has been built with
+qt5, it will be disabled in OpenCV unless it too is being built with qt5.
+
+Documentation is generated by the SlackBuild unless it is switched off
+by setting the CVDOCS environment variable i.e.
+    CVDOCS=no ./opencv.SlackBuild
+The graphviz package is an optional dependency for enhanced
+documentation.
