Where can I download cuparticle.cls file

Question

When I compile my document. LaTex shows the error:

File, 'cuparticle.cls' not found.

Where can I find this file.

The file is for Cambridge University Press. Actually, the Journal is Forum of Mathematics, Pi. In read me file, the following is instructed:

You need the following file:

cuparticle.cls

Please use the documentclass option fmp'. For example:

\documentclass[% 
  fmp, times, 
]{cuparticle}

Here is the link((https://www.cambridge.org/core/journals/forum-of-mathematics-sigma/information/instructions-contributors) ) to zip file containing LaTex file which I try to compile. Please click on, "LaTeX template files for submission" inside the link.

Answer 1

The problem with the zip file from the given link is that there is no file cuparticle.cls but cuparticle v2.cls:

Copy the given files to a new directory and rename cuparticle v2.cls to cuparticle.cls. Then you can compile the given file fms-template.tex file without that message you got ...

Answer 2

The Journal is Forum of Mathematics, Pi author instructions page provides a page to download a zip file that contains cuparticle.cls. It looks like the class was developed by RVT but the download link on the wiki appears dead and the wayback machine isn't helpful.
