Our KET files follow the format of [Ketcher](https://github.com/epam/ketcher)
(EPAM Systems, Apache-2.0); no Ketcher code is part of this site.

Not yet collected here: the C/C++ libraries compiled into the two
WebAssembly files. Indigo's source tree vendors cairo, pixman, freetype,
libpng, zlib, InChI, RapidJSON, tinyxml2 and lunasvg (the "norender" build
used here leaves out the rendering ones); RDKit's MinimalLib includes at
least CoordGen, maeparser and InChI. All use permissive licenses.
