 Twine is a command line tool for managing your strings and their translations. These are all stored in a single text file and then Twine uses this file to import and export localization files in a variety of types, including iOS and Mac OS X `.strings` files, Android `.xml` files, gettext `.po` files, and [jquery-localize][jquerylocalize] `.json` files. This allows individuals and companies to easily share translations across multiple projects, as well as export localization files in any format the user wants.
