Help with a custom plugin (post.title translation)

Hey guys,

I’m good with Python but have no experience with Ruby and feel a bit lost. I was hoping if someone could point me in the right direction.

I have made a tiny project with a given custom plugin, that I wish to fix/extend: https://github.com/houmie/website

The plugIn is here: https://github.com/houmie/website/blob/master/_plugins/jekyll-multiple-languages-plugin/jekyll-multiple-languages-plugin.rb

As stated in the README -> ‘Problem 1’, can somebody tell me which function in the plugin is taking care of the post.title translation?

Many Thanks,
Houman
