   edu.harvard.hul.ois.jhove.ConfigWriter
edu.harvard.hul.ois.jhove.ConfigWriter
- public class ConfigWriter

Class to write out configuration information to the configuration file.

 temporary file, then replaces the old config file with that file,
 rather than directly overwriting the existing file.
