+This Specification describes the snow syntax and semmantics as well as
+how to decode snow.
+The decoding process is precissely described and any compliant decoder
+MUST produce the exactly same output for a spec conformant snow stream.
+For encoding though any process which generates a stream compliant to
+the syntactical and semmantical requirements and which is decodeable by
+the process described in this spec shall be considered a conformant
+snow encoder.
