Binary package “xfig-doc” in ubuntu cosmic

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.
