This is a port of ivtools, a collection of vector-graphic drawing editors which augments the original idraw from Stanford University with mechanisms for scripting, networking, animation, and graph-editing. They also add support for additional raster formats (PBM/PGM/PPM, PNG, GIF), arbitrary PostScript (using pstoedit), and export/import via Unix filters. WWW: http://www.ivtools.org/ivtools/
