Acoustics Toolbox
-----------------

``at-py`` is a Python port of Matlab-side tooling and file layouts from the
`Acoustics Toolbox <https://oalib-acoustics.org/website_resources/AcousticsToolbox/versions/at/>`_.
It does not embed or re-implement the Fortran numerical kernels.

The canonical Fortran/Matlab distribution is published for the ocean acoustics
community by Michael B. Porter and is released under the GNU General Public
License v3 or later. A public mirror used by this project for source references
is `github.com/jgebbie/at <https://github.com/jgebbie/at>`_.

Project License

``at-py`` is released under the GNU General Public License v3 only. See the
repository ``LICENSE`` file.

The license is intentionally compatible with the Acoustics Toolbox ecosystem.
When distributing a combined stack of runner, AT binaries, and Python client
libraries, apply GPL obligations to the combined distribution.

   Mirrored Acoustics Toolbox Fortran and Matlab sources. The upstream material
   is GPLv3-or-later.

``github.com/jgebbie/at-runner``
   gRPC runner around AT executables. If distributed together with GPLv3 AT
   binaries, it should declare a GPL-compatible license; GPLv3 is the simplest
   aligned choice for a combined stack.
