What does hugin use for lens correction?

[Tommy Hughes]

I am trying to write a script to automate processing but I don't know how to do lens correction. I mentioned in another post (https://groups.google.com/g/hugin-ptx/c/QOYyh3NG56k) that fulla does not work for me. How does hugin do lens correction, and how can I do that in a script? One option is to develop the raws with rawtherapee, but I wondered if there was an independent lens correction method?
