I'd like to customize some of the language that WeBWorK uses in certain messages and labels that students see. There are several things I'd like to change, but for the sake of an example, I'd like to change most instances of the word "problem" to "exercise".
Now, how to go about doing this? At first I thought to copy the en.po localization file to a new file, say pcc.po. Make edits to pcc.po, and then set the "language" to pcc in localOverrides.conf. I did that and it works in the sense that the messages now use "exercise" instead of "problem".
However this simultaneously makes the site's HTML pages have lang="pcc" in their html root element. And that seems like something I shouldn't allow to happen.
Is there a good way to do what I am trying to do? I'm still using English, just modified from the distribution content. I could directly edit en.po, but I don't want conflicts with origin/main.
