swatplus-bmi is under two licenses.

- fortran/ and patches/ (the exchange mode added to SWAT+) and any SWAT+
  built with them: GNU Lesser General Public License, version 2.1, the
  license of SWAT+ itself. See LICENSES/LGPL-2.1.txt.

- Everything else, including the Python wrapper in src/swatplus_bmi/, the
  tests, tools and documentation: BSD 3-Clause. See LICENSES/BSD-3-Clause.txt. The wrapper is
  a separate program: it starts SWAT+ as its own process and talks to it
  over standard input and output, and is not linked with it.
