A system and method is provided wherein a software file or packaged set of files, originally prepared in one natural language, is sent to a translator for translation into another natural language. The translated file or files is then delivered back from the translator, to an automated error checking tool. The tool performs a number of different error checking functions on the file, to determine if the file has any of a number of different types of errors resulting from the translation. Usefully, different error checking devices are provided to search for errors of different types or classes. The tool is operated in association with a firewall, to ensure that files with errors cannot be introduced into the software development-build environment. The translator is automatically notified via electronic mail if errors are found in his/her files.
