XFIG - Facility for Interactive Generation of figures under X11 Xfig is a menu-driven tool that allows the user to draw and manipulate objects interactively in an X window. The resulting pictures can be saved, printed on postscript printers or converted to a variety of other formats (e.g. to allow inclusion in LaTeX documents). To enjoy the beautiful colors, specify "*customization: -color" in your .Xdefaults or .Xresources file.
