Description:
XFig on-line documentation and examples
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. If the fig2dev program is installed, which is contained in the fig2dev package, the pictures can be printed on postscript printers or converted to a variety of other formats (e.g. to allow inclusion in LaTeX documents or web pages). . This package contains on-line documentation in HTML and PDF formats as well as the graphics examples distributed with XFig.
