1. Add to the root folder of your prism-break copy.
2. Run by writing node copystubs.js in the terminal.
3. Watch the output.

The output will tell you 2 things:

1. If it has added projects from en-projects.json to any other localisation file.
2. If any localisation file contained projects of which the slugs did not excist in en-projects.json.

The warnings given by step 2 are only warnings, you will have to resolve them yourself. This script does never remove content from a file, it only adds.
