[swfmill] How to use swfmill to check the duration of a swf

[Ralf Fuest]

You simply divide the frame count by the framerate value in the header
to get the duration in seconds.
To get the number of frame in the main timeline of your swf file you
need to count all ShowFrame tags, wich aren't embedded in another tag
(e.g. in an DefineSprite tag).
