// This is a convenience script for replacing the contents of translated
// files with the English content from their corresponding source file.
//
// It's intended to be a workaround to temporarily bypass Crowdin parser bugs
// while we wait for Crowdin to fix them.
//
// Usage:
// script/reset-translated-File.js <relative-filename> [<two-letter-language-code>]
//
// script/reset-translated-File.js content/desktop/foo.md
// -> resets all translations of foo.md
//
// script/reset-translated-File.js content/desktop/foo.md de
// -> resets german translation of foo.md
//
