sachugowda/Latex_Journal_to_Journal_Template_Converter ? reverse-engineered prompt

Build me a Python tool that takes a LaTeX paper written for one journal and converts the whole project into another journal’s template.

I want to be able to point it at a source zip, point it at an empty target template zip, and get back a new zip that is ready to upload. It should handle multi file Overleaf projects, include files, custom commands, figures, bib files, and copy over the target template’s own style files so the result still compiles. It should also figure out the target journal’s structure from the sample content in the template, like how the title, authors, abstract, keywords, and required declaration sections should be formatted.

Please also have it create a clear review checklist and a notes file so I know what needs manual checking. If you need to, look up current docs online for LaTeX class behavior, but keep the tool dependency free and use only standard Python.
