Modelsim missing in tools

[garankonic]

If installing edalize with pip, there are two files ./edalize/modelsim.py ./edalize/tools/modelsim.py (see package contents - https://pypi.org/project/edalize/#files). However, in the edalize source code ./edalize/tools/modelsim.py is missing in. Where does this file come from?
I had to copy ./edalize/tools/modelsim.py from the packaged version to the source folder to make sim flow working with modelsim.

Thanks a lot in advance for the clarification!
