-Graphics code for non-LaTeX users.
-==================================
-
-This directory provides a small wrapper file such that users of
-formats based on plain TeX may make use of some of the parts of the
-standard LaTeX distribution.
-
-These files are *NOT* supported by the LaTeX3 project, and any
-problems with them should *NOT* be reported to the LaTeX bugs system.
-
-Currently problems may be reported to me, david@dcarlisle.demon.co.uk
-although as I only ever use LaTeX for documents, these files have not
-been extensively tested. If some plain TeX user wants to `adopt' them
-and take over their support then they are welcome to it:-)

-This directory contains
-
-00readme.txt This file.
-
-exmplpic.tex
-      A plain TeX document using LaTeX' `picture mode': a portable
-      means of producing simple diagrams.
-
-exmplgrf.tex 
-      A plain TeX document using the LaTeX graphicx package, for
-      rotating and scaling text, and include PostScript and other
-      graphics formats. (This will include the file a.ps available
-      in the LaTeX graphics distribution.)
-
-exmplcol.tex
-      A plain TeX document using the LaTeX color package, for
-      producing colour.
-
-exmplpfg.tex
-      A plain TeX document using the contributed LaTeX psfrag package,
-      for including PostScript documents, while replacing certain text
-      strings with TeX typeset replacements. This uses the example.eps
-      figure from the psfrag 3.0 distribution.
-
-miniltx.tex
-      A small `miniLaTeX' that defines fakes or otherwise hacks
-      sufficient bits of LaTeX internals so that the packages can load.
-
-picture.tex
-      The user interface to the picture environment.
-      \input picture.
-      Normally a plain-style syntax is used, viz
-      \picture(100,100)
-      ....
-      \endpicture
-
-      However if the command \LaTeXbegin is issued, then a LaTeX
-      syntax of
-      \begin{picture}(100,100)
-      ....
-      \end{picture}
-      May be used. this may be prefered if the picture is being copied
-      from a LaTeX document, or if it is produced automatically from
-      a drawing tool such as xfig or texcad.
-
-autopict.ins
-      picture.tex requires the use of the Standard LaTeX file
-      autopict.sty. To generate this, either run the autoload.ins
-      install file in the main LaTeX distribution, which will make
-      autopict.sty along with some other files (not needed here) or
-      alternatively just obtain obtain ltpictur.dtx and docstrip.tex
-      from the LaTeX distribution, and TeX the file autopict.ins that
-      is included in this distribution.
-
-
-graphicx.tex
-      The user interface to the graphicx package.
-      \input graphicx
-      See the documentation in grfguide.ps in the LaTeX graphics
-      distribution.
-      This file sets the driver to be dvips. If you
-      use another driver, edit accordingly.
-
-color.tex
-      The user interface to the color package.
-      \input color
-      See the documentation in grfguide.ps in the LaTeX graphics
-      distribution. 
-      This file sets the driver to be dvips. If you
-      use another driver, edit accordingly.
-     
-
-psfrag.tex
-      The user interface to the psfrag package.
-      \input psfrag
-      See the documentation in pfgguide.tex in the psfrag distribution,
-      and the example document pfgexmpl.tex included here.
