NAME
README.user_data.pod
Purpose of the directory
For each instance of the web-interface a directory is created under this user_data directory. These user directories remain in user_data directory until the processing is complete. Once the processing is complete the user directory is moved to htdocs/allwords directory. If an error occurs and processing is interrupted then the user directory remains here.
So ideally this directory should act only as a temporary residence for these user directories and should contain only this README.user_data.pod file.
