tool to generate a set of .svg files out of a single .svg file

 svgtune is a little helper to generate a set of .svg files out
 of a single .svg file, by tuning respective groups/layers visibility,
 transparency or anything else.

 It might come very handy for generation of incremental figures to be
 embedded into the presentation in any format which inkscape could
 render using original .svg file (e.g. pdf, png).
