Naive question: The github page says 62% of the languages used in this repo is FreeMarker. I checked the repo and every file I look at is js, what and where is FreeMarker?
Ex: https://github.com/timvisee/send/blob/master/public/locales/...
If you look at github/linguist, that's what recognizes languages in repos. It has this rule for FreeMarker: https://github.com/github/linguist/blob/32ec19c013a7f81ffaee...
It seems a .ftl extension means FreeMarker to linguist, so those localizations show up as such.
If you run `git check-attr --all public/locales/foo/send.ftl` with the current .gitattr file, you'll get no attributes.
If you update the attr match to `public/locales/**` or `public/locales/**/*.ftl`, then the `check-attr` command above will match it and show 'linguist-documentation'.
The parent repo doesn't have this issue. The "languages" list doesn't mention Freemarker on https://github.com/mozilla/send
