* This class shows how to dump a TikaConfig object to a configuration file.
* This allows users to easily dump the default TikaConfig as a base from which
* to start if they want to modify the default configuration file.
*
* For those who want to modify the mimes file, take a look at
* tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml
* for inspiration. Consider adding org/apache/tika/mime/custom-mimetypes.xml
* for your custom mime types.
