+    This is generator of CLapack subset.
+    The usage:
+
+    1. Make sure you have the special version of f2c installed.
+       Grab it from https://github.com/vpisarev/f2c/tree/for_lapack.
+    2. Download fresh version of Lapack from
+       https://github.com/Reference-LAPACK/lapack.
+       You may choose some specific version or the latest snapshot.
+    3. If necessary, edit "roots" and "banlist" variables in this script, specify the needed and unneeded functions
+    4. From within a working directory run
+
+       $ python3 <opencv_root>/3rdparty/clapack/make_clapack.py <lapack_root>
+       or
+       $ F2C=<path_to_custom_f2c> python3 <opencv_root>/3rdparty/clapack/make_clapack.py <lapack_root>
+
+       it will generate "new_clapack" directory with "include" and "src" subdirectories.
+    5. erase opencv/3rdparty/clapack/src and replace it with new_clapack/src.
+    6. copy new_clapack/include/lapack.h to opencv/3rdparty/clapack/include.
+    7. optionally, edit opencv/3rdparty/clapack/CMakeLists.txt and update CLAPACK_VERSION as needed.
+
+    This is it. Now build it and enjoy.

+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
