     "Xfig is an interactive drawing tool which runs under X Window System.
In xfig, figures may be drawn using objects such as circles, boxes, lines,
spline curves, text, etc.  It is also possible to import images in formats
such as GIF, JPEG, EPSF (PostScript), etc.  Those objects can be created,
deleted, moved or modified.  Attributes such as colors or line styles can be
selected in various ways.  For text, 35 fonts are available.")
