  23 # SVG2S60 - Cleans Inkscape SVG files for use with svg2svgt in the S60 SDK
  24 #
  25 # Usage: svg2s60.pl in.svg > out.svg
  26 #
  27 # Description: This script just splits the style tags used by Inkscape, but not
  28 # properly supported by svg2svgt into it's seperate components. This helps to
  29 # solve color mapping issues in svg2svgt for files that have been edited by
  30 # Inkscape.
