Hi,

The troi repository has a LICENSE file containing the GPLv2, however the pyproject.toml file mentions GPLv3.

Apart from these, I could not find any copyright headers that would say that the license actually applies to the files in the repository and if it is “or any later version”.

With the approval of the copyright holders, could you please add copyright headers to source files or at least in the README to clarify the licensing of the project?

Thanks,  
Noé Lopez
