2 * OpenDocument <drawing> input and output
3 *
4 * This is an an entry in the extensions mechanism to begin to enable
5 * the inputting and outputting of OpenDocument Format (ODF) files from
6 * within Inkscape. Although the initial implementations will be very lossy
7 * do to the differences in the models of SVG and ODF, they will hopefully
8 * improve greatly with time.
