+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.
+
+Problems should be reported as issues at
+https://github.com/davidcarlisle/dpctex/tree/master/graphics-pln

+This directory contains
+
+README.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.sty
+ This is a frozen copy of a file that used to be distributed with
+ LaTeX but is no longer needed in that context, it is basocally
+ the source of LaTeX Picture mode from LaTeX in 2014. The
+ original use for this package was to build a latex format in
+ which some environments such as picture and tabbing were not
+ defined by default, to save space if working with TeX on a
+ machine with 640K memory.
+
+
+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.
