+== Requirements for the Haskell ==

+The Haskell solution requires Text.JSON to be installed.  On Debian derivatives the package name is libghc6-json-dev
+
+== Requirements for the Scala ==
+
+The Scala solution requires a JAR file for Jackson (the Java JSON parser) in the top level called jackson.jar.  It also requires all the source code or class files from <https://github.com/codahale/jerkson> be at the top level.
