The GOBLIN project consists of a C++ class library for a large series of graph optimization problems, GOSH, an extension of the Tcl/Tk scripting language to graph objects, and GOBLET, a graphical user interface to the library functions. GOBLET includes a graph editor and supports the standard graph layout methods. License: GNU Lesser General Public License (LGPL) Changes: This release features a general cleanup of the GUI, and several improvements of the arc and node display parameters: arc widths, stipple modes, and colours can be assigned independently from each other. The fonts for node and arc labels can be selected, and font sizes scale with the general zoom.
