The content of this directory is partially sourced from the fluent.js project. The following files are affected: - MessageContext.jsm - Localization.jsm - DOMLocalization.jsm - l10n.js At the moment, the tool used to produce those files in fluent.js repository, doesn't fully align with how the code is structured here, so we perform a manual adjustments mostly around header and footer. The result difference is stored in `./fluent.js.patch` file which can be used to approximate the changes needed to be applied on the output of the fluent.js/fluent-gecko's make. In b.m.o. bug 1434434 we will try to reduce this difference to zero.
