# This can be reduced to the actually needed locales via a jlink paramter,
# e.g., --include-locales=en,de.

# Use the jlink tool to create a runtime image for our application. We are
# doing this is a separate step instead of letting jlink do the work as part
# of the jpackage tool. This approach allows for finer configuration and also
# works with dependencies that are not fully modularized, yet.
