Hi all,

Is this the competely grammar of cif files ?

CIFFile = {SymDefinition | Geometry} E.
SymDefinition = DS int [int int]; {Geometry} DF;.
Geometry = Layer | Box | Polygon | Polyline |
                 Circle | Call | Extension | Comment.
Layer = L letter{letter|digit};.
Box = B int int Point.
Polygon = P Point {Point};.
Polyline = W int Point {Point};.
Circle = R int Point;.
Call = C int Transform;.
Transform = {Mirror | Rotation | Translation}.
Mirror = MX | MY.
Rotation = R Point.
Translation = T Point.

Extension = int {char};.

Comment = ({char});.
Point = int int.

The following extensions are understood:
- Symbol names:         Extension = 9 {char};
- Text labels (that appear in a layer at  the given coordinates): 
                        Extension = 94 {char} Point;


If it isn't the right grammar, please send me the right one.

Thanks,
German.
