At some point, a report of the baselevel changes is generated including a list of all newly created files in the first human language which have not been translated into the second human language and all translated files in the second human language which are downlevel. A real-time status of build process is provided to a developer of the computer software utilizing information from the library control database field. tracking all baselevel changes of said software in a first human language. The report is analyzed to give a real-time status of build to a developer of said computer software.
