// A message from upstream:
// ========================
// To avoid adding a lot of boilerplate, locale packs are
// automatically generated here. These are written into the tmp/
// directory and then used to generate locale_en.js, locale_fr.js, etc.
// Glitch note:
// ============
// This code has been entirely rewritten to support glitch flavours.
// However, the underlying process is exactly the same.
