              TeX macro package to create 2D or 3D figures
                in both DVI (PostScript) and PDF modes.

  Keywords: graphic, geometric construction, labelling, figure insertion.

  Fig4TeX is a macro package whose purpose is to facilitate the creation and
the management of figures in a TeX document. Used for several years by many
users, Fig4TeX has the following characteristics:

 - It works with plain TeX and LaTeX formats, and switches automatically
   between DVI mode and PDF mode, according to the compilation program used
   (tex-latex or pdftex-pdflatex).

 - Its conception was guided by three major aims:
    . first to locate all the pertinent information inside the TeX document,
    . second to provide geometrical tools to create figures in 2D and 3D,
    . third to enable annotations on the figures in an easy and accurate way.

 - It allows to make true geometric constructions in a flexible way, since
   points can be defined as symbolic entities, as the result of mathematical
   transformations or geometrical definitions, which ensures that the shape
   of the figure can be easily modified at any time.
   Thus a figure can be parametrized by some characteristic data.

 - The annotations are linked to the figure, so that they "follow" automati-
   cally the modifications of the figure.

 - The annotation feature allows what is generally called "graphics labelling",
   i.e. text or formulae can be written on any figure, including those made
   by other softwares.

 - Fig4TeX sticks to TeX's machinery since it makes each figure treated by
   TeX as a box, whose dimensions depend on the drawing and the annotations,
   which ensures that the typesetting process rely entirely on TeX.

 - For the sake of compatiblity with other packages, Fig4TeX uses few registers
   and a warning message is issued if a macro name is previously defined.


  The Fig4TeX distribution consists of three files:
 . README (this file),
 . fig4tex.sty (LaTeX interface),
 . fig4tex.tex (macro file),
 which can be downloaded from the web site

  Fig4TeX also comes with a PDF documentation, a hypertext reference guide,
a hypertext tutorial and various examples, all of them available on the web site.

  The installation process simply consists in copying the files to the right
place as explained on the web page:
