+/* sprites.c
+
+   Demonstration of using different timelines (sprites)
+
+   Remarks:
+   
+   * rfxswf uses a flat tag list
+     All sprite tags between ST_DEFINESPRITE and ST_END
+     will be packed into the data of the ST_DEFINESPRITE
+     by the output routines
+
+   * make sure, that all defining tags are placed
+     outside the sub-timelines (i.e. before ST_DEFINESPRITE)
+
+   * framerate is global (sad but true!)
+
+   Part of the swftools package.
