+Python3 bindings for opencv matching system opencv version.
+
+Please note that python3-numpy is a runtime dependency as
+well as a build time dependency. Installing the resulting
+python3-opencv package without python3-numpy already installed
+will create unpredictable behaviour i.e.
+  first install python3-numpy
+  then  install python3-opencv
+
+By default, additional "contrib" modules are included. If these
+are not wanted, set the CONTRIB environment variable to 0
+e.g.
+  CONTRIB=0 bash python3-opencv.SlackBuild
+
+A successful installation can be quickly tested by runnng the
+ocv-test.py script found in the documentation directory
+
+OPTIONAL EXTRAS
+  The following installations are automatically detected and
+used if available at build time:
+ - VTK visualization and image processing
+ - libdc1394 IIDC/DCAM/Firewire based camera control
+ - zulu-openjdk17 Java Development Kit
+   (other Java varieties probably also work)
+ - apache-ant Java build tool
+  (only relevant if Java is also detected)

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
