Translation?

Hi,
I'm a technology teacher and I would like to use something simple like UMLLight or Papyrus4Education to help students to create diagrams by themselves.
As I'm looking only for few SysML diagram, I think I can use Package Diagram as a Block Diagram.
But what is a real problem for them is that everything is in english, how can I translate Papyrus Light ? Shoud I only work on source and compile again ? Or is there any file I can modifiy?
Thanks, hope you'll update this project.

The issue names no file, test, or entry point. Start by locating how Papyrus Light stores its user-facing English text and whether any translation mechanism exists; done would mean identifying a practical way to translate the application, with the required implementation or configuration scope clearly documented.
