1. Introduction
  Molecular Coding Format(MCF) is new linear notation represent chmical 
 structure diagram. This 'Coding' is named from coding(programing) technique
 like adressing,grouping,macro. There are no commands of Meta language in MCF.
 mcf2graph.mf(metapost/metafont macro) convert MCF file to graphic file
 (pk font/PNG/SVG/EPS) or MDL MOL file(V2000).
 The software,MCF manual,TeX example can get from authors web site.

2. The distribution of software
 ( 1) README                 This file
 ( 2) mcf_graph.mf           Macro of Metafont / Metapost
 ( 3) mcf_manual.tex         MCF syntax manual(LaTeX file)
 ( 4) mcf_man_soc.mf         Molecular difinition file for mcf_manual.tex
 ( 5) mcf_man_soc-032.eps    No.32 EPS(with color) file of (4)
 ( 6) mcf_manual.pdf         PDF of (3) (used LaTeX,dvipdfmx)
 ( 7) mcf_example.tex        LaTeX example,
                               Make 'mcf_exa_soc-info.log' before typeset
                               mpost -s ahangle=0 mcf_exa_soc.mf
 ( 8) mcf_exa_soc.mf         Molecular difinition file for mcf_example.tex
 ( 9) mcf_example.pdf        PDF of (7) (used LaTeX,dvipdfmx)
 (10) mcf_mplib_exa.tex      LuaLaTeX example, use package luamplib.sty,fancyvrv.sty
 (11) mcf_example.pdf        PDF of (10) (used LuaLaTeX)

3. How to use mcf2graph with Metapost
 ( 1) mpost -s ahangle=1  FILENAME  output PNG file. (default value is eps)
 ( 2) mpost -s ahangle=2  FILENAME  output SVG file. 
 ( 3) mpost -s ahangle=3  FILENAME  output MDL Molfile(V2000)
 ( 4) mpost -s ahangle=0  FILENAME  output no graphic file.
 ( 5) mpost -s ahlength=1 FILENAME  output first definition only (for test)
 ( 6) mpost -s ahlength=2 FILENAME  output checklist.

4. Molecular definition file example
 input mcf2graph.mf;   % input main system
 font_wd#:=30mm#;      % font width
 font_ht#:=20mm#;      % font height
 max_bond_width:=0.2;  % max fond length/font width
 sw_logout:=1;         % log file out
 %***********************************************************************
 beginfont("EN:Acetamiprid")             % Molecular name 1
   MCf(^^30,Ph,4\,!,NH,!,!~dr,N,!,CN)%   % Molecular Coding Format
 endfont

5. How to use mcf2graph with TeX(latex)
 Large number of molecular structures can be gathering by using TEX.
 mcf_example.tex is example of using LaTeX.

 \documentclass[a4paper]{article}
 \usepackage[dvipdfmx]{graphicx}%  Change option depend on your tex system

 % insert part of info LOG file
 %-------------------------------------------------------------------------
 \MOLinfo{EN:Acetamiprid}{:}{:}{:}%
 {:}{:}{:}{:}%
 {:}{:}{:}{:}%
 \MCFinfo{MCF_SOC2}{0}{MCF_SOC2-000.eps}{419.14972}{145.32037}{159.04236}{12}{0}{}%
 %-------------------------------------------------------------------------
 % or insert next line
 \input mcf_exa_soc-info.log  % filename of souce file : mcf_exa_soc.mf
