ngparse Licensing

Copyright (c) 2026 Justin Fisher
All rights reserved.

ngparse is licensed under the `Modified BSD' license -- the same license
ngspice adopts for its own source code, so that the two may be combined and
redistributed together without friction.  ngparse links into ngspice as a
static library, and the ngspice glue that calls it (see changes.txt) is
likewise Modified BSD.

This license applies to all of ngparse: parser/, include/ and the
build files.

******************************* dependencies **********************************

ngparse has no third-party dependencies.  The parser crate declares none, and
the built static library links only against the Rust standard library and the
platform C runtime (-lpthread -ldl -lm).

******************************* ngspice *************************************

ngspice itself is not covered by this file.  ngspice is a mixture of licenses
-- Modified BSD for the bulk of it, with exceptions (its KLU and tclspice parts
are LGPLv2, src/osdi is MPLv2.0, src/xspice is largely public domain, and so
on).  See ngspice's own COPYING.  The files ngparse adds to or modifies in the
ngspice tree are listed in changes.txt; all of them sit in parts of ngspice that
are Modified BSD.
