+# don't expect too much.
+# this is a really simple&stupid svg parser, which will use rectangles 
+# and text fields to produce <widget> snippets for a skin.
+# use object "id" fields for source names if you want.
+# extracting font information is buggy.
+# if you want text fields, please use flow text regions, instead of simple
+# text. otherwise, width and height are unknown.
+#
+# tested only with a single inkscape-generated SVG.
