This project provides a LaTeX class aiming to implement the style sheet of the Cascadilla Proceedings Project (http://www.lingref.com/cpp/authors/style.html).
If you are writing a paper for proceedings published by the Cascadilla Proceedings Project and you use XeLaTeX and biblatex, you will hopefully be able to submit a properly typeset version using this class.
There is an existing LaTeX-class for Cascadilla proceedings, Max Bane's
cascadilla.cls (https://github.com/maxbane/cascadilla.cls/). If you
use (pdf)LaTeX and natbib/bibtex, that's what you're looking for.
Personally, I am using this to write a paper for the proceedings of WCCFL 2020 and I'll be fixing any issues that I come across in the process. Thus, there is no proof (yet) or guarantee that a paper typeset using this class will be accepted, but that's the aim.
