(format "Extreme Wave")
(version "0.1")

; This is an example of the revised Extreme Wave format.  The new 
; format uses a lex/yacc grammar.  This makes the file parsing much more
; robust and much easier to maintain.

; All points are referred to by index from a point list.

; Note: this was hand generated as an example.  Extreme Wave always outputs
; every posible property for any element.  This is a perfectly valid file,
; but I have omitted many (most) properties, to show how simple it is,
; and to show how minimalistic it can be and still be valid when loading
; from Extreme Wave.
