xfig binary package in Ubuntu Bionic i386

 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 the xfig program itself.
 .
 You should think about installing the fig2dev package to export the
 graphics to several common formats. You should also think about
 installing xfig-doc, which contains the documentation and xfig-libs,
 which contains several clip art libraries.
