1. Introduction
 Molecular Coding Format(MCF) is new linear notation represent
 chemical structure diagrams.
 This Coding is named from programing technique
 such as operator,array,scope,macro,adressing,etc.
 mcf2graph convert from MCF to SVG,PNG,MOL file.
 It is also able to calculate molecular weight,exact mass,molecular formula.

2. The distribution of software
 ( 1) README             This file
 ( 2) CHANGELOG          Changelog file of mcf2graph
 ( 3) mcf_to_graph.cmd   Batch file for compile mcf or mp file
                         drag and drop mcf or mp file on this batch
                          >mcf_to_graph main_lib.mcf
                           create graphic files in ./main_lib-(format)

                           create graphic files in ./template_lib-(format)
                          >mcf_to_graph mcf_exa_soc.mp
                           create graphic files in ./mcf_exa_soc-mp

3. Minimum required files to use mcf2graph
 Install texlive or other distribution
 These files are available from texlive2026.iso in the case of texlive
 (1) mpost.exe
   (TeXLive2026/archive/metapost.<os>.r<number>.tar/bin/<os>/mpost.exe)
 (2) mpost.dll
   (TeXLive2026/archive/metapost.<os>.r<number>.tar/bin/<os>/mpost.dll)
 (3) mpost.mp
   (TeXLive2026/archive/metapost.r<number>.tar/texmf-dist/metapost/base/mpost.mp)
 (4) plain.mp
   (TeXLive2026/archive/metapost.r<number>.tar/texmf-dist/metapost/base/plain.mp)

4. Use mcf2graph with MetaPost
     -command line-
 (1) >mcf_to_graph        filename.mcf => output svg,png,mol,report
 (2) >mcf_to_graph        filename.mp  => output svg(default),LV=0(default)
 (3) >mpost               filename.mp  => output svg file
 (4) >mpost -s ahangle=1  filename.mp  => output png file (600dpi)
 (5) >mpost -s ahangle=2  filename.mp  => output png file (1200dpi)
 (6) >mpost -s ahlength=5 filename.mp  => output mol file(V2000)
 (7) >mpost -s ahlength=6 filename.mp  => output mol file(V3000)
 (8) >mpost -s ahlength=7 filename.mp  => output report file
