 Okay, you're ready to move onto the examples now.

 Examples
 --------
 
+Using raw data from the parser. Note that "@" isn't translated in this mode.
+Nor are inherited TTLs interpreted.

   zonefile = "/path/to/file.zone"
   zone_string = File.read(zonefile)

+Using more structure data. @, TTLs, and empty hostname inheritance are all
+handled in this mode.
