As I'm pretty happy with my implementation and I'd like to make a pull request soon: Can someone give me a hint where to find guidelines for adding translations? Is is obligatory to run some automated tool like `xgettext`?
Else I'd simply add a ``` msgid "_Current Line Error" msgstr "_..."
``` below the `Previous Error` translation to each `po/*.po` file. And I would use some automated translation system (e.g. Google Translate) for most of the languages.
