FST file format, libfst and lisencing

[keesj-riscure]

Hello

I see multiple project embracing the FST format and also do some efforts in documenting it https://docs.rs/fstapi https://blog.timhutt.co.uk/fst_spec/

As GTKWave is released as GPLV2 am wondering if libfst fals under the same regime. As this tool, and format is used by different parties using more permissive licenses it would make sense and it would be nice to clarify the license for the library and format.

For short .. what it the LISENCE on libfst? Is it what the header suggest MIT?

https://github.com/gtkwave/gtkwave/blob/master/lib/libfst/fstapi.h#L22

License for libfst and all the format readers/writers are MIT, basically as permissible as possible as far as open source licenses go without simply releasing it as public domain.

Since gtkwave is a GitHub organisation now (see https://github.com/gtkwave/gtkwave/issues/3) it would be straightforward to move the waveform utils/libs (https://github.com/gtkwave/gtkwave/tree/master/lib and https://github.com/gtkwave/gtkwave/tree/master/contrib) to a sibling repo and have it submoduled in this one. It would make it more explicit not only the licensing but also the fact that those libs/utilities for dealing with multiple waveform formats can be useful besides the main gtkwave (the gtk GUI).
