+### Utility functions
+The main purpose of this repository is to maintain the JSON translation files. However 2 utility functions are also included for JavaScript/TypeScript projects.
+
+- `getModuleInfo(sysmodule, locale)` - Returns the module information for the locale, or `null` if not found
+- `getErrorInfo(sysmodule, code, locale)` - Returns the error information (including the module information) for the locale. Returns null if either the module or error code is not found
+- `getAllErrors()` - Returns an array of all error codes for all modules in the form `MODULE-CODE`
