Corresponding Source:
---------------------
The three compiled C libraries (libbulkxcorr2d, libfusedwarp, libkspacefit)
are original work of this project. Their complete source is distributed in the
sdist under pivtools_cli/lib/, together with the codelet generator that emits
the FFT kernels at build time. They link only OpenMP and the C math library;
no third-party numerical library is bundled or statically linked.

Other Dependencies:
-------------------
This software uses various third-party open-source libraries (NumPy, SciPy,
OpenCV, Flask, etc.) which are distributed under permissive licenses (BSD,
MIT, Apache 2.0). These are compatible with the GPLv3 terms above. See each
package's documentation for specific license terms.
