/*
The non-suffixed passages are here to prevent Twine from
complaining endlessly about missing passages, SugarCube from
showing broken links, and to keep the story history free of
suffixed passage names so that changing languages on the fly
will work.
The actual passages are the language code suffixed versions.
For example, for this starting passage the German version
would be Start_de, the French Start_fr, and English Start_en.
When creating links between passages, you must always link to
the non-suffixed versions and never to the suffixed versions.
The postrender task will handle displaying the correct version
based on the currently selected language.
NOTE: While nothing within the non-suffixed passages will be
displayed, they will be rendered. Meaning side-effects from
included code will be in effect—e.g. modifications to story
variables. Thus, you should either leave them empty or place
all contents within comment blocks—like this one.

Assuming you mean that you want it to change based on the currently selected language, then you do not without dipping into undocumented internals. The Setting API in SugarCube v2 was never designed with language switching in mind, so the order that various operations happen in is not conducive to what you'd like to accomplish.

If something which does not integrate into the Setting dialog would be acceptable, then there's the alternative example sc-i18n-example-2.twee.
