 Apache Tika v2.x brings with it some changes. One key change is that the Tika client and server applications have
 been split up. To keep the gem size down Henkei will only include the client app. That is to say, each time you
 call to Henkei, a new Java process will be started, run your command, then terminate.
 
 Another change is the metadata keys. A lot of duplicate keys have been removed in favour of a more standards
-based approach. A list of the old vs new key names can be found [here](https://cwiki.apache.org/confluence/display/TIKA/Migrating+to+Tika+2.0.0#MigratingtoTika2.0.0-Metadata)

+`text` or `html` instance methods, as well as the `read` class method.
