+% This file is a part of the macro package ``XyMTeX'' which has been
+% designed for typesetting chemical structural formulas.

+% This file is to be contained in the ``xymtex'' directory which is
+% an input directory for TeX. It is a LaTeX optional style file and
+% should be used only within LaTeX, because several macros of the file
+% are based on LaTeX commands.
+%
+% For the review of XyMTeX, see
+% (1) Shinsaku Fujita, ``Typesetting structural formulas with the text
+% formatter TeX/LaTeX'', Computers and Chemistry, in press.
+% The following book deals with an application of TeX/LaTeX to

+% \subsection{Macros for treating argumets}
+%
+% For separating each argument (BONDLIST, SUBSLIST or ATOMLIST) into
+% components (descriptors), we define several useful macros.
+%
+% \begin{macro}{\@forsemicol}
+% \begin{macro}{\@forl@@p}
+% \begin{macro}{\@iforl@@p}
+%
+% The macro |\@forsemicol| resembles the |\@for| macro that is
+% the \LaTeX{} original macro; however a semicolon is used as
+% a separating key in place of a comma.
+%
+% \changes{v1.01}{1996/07/06}{\cs{@forsemicol}: \cs{edef}
+% to \cs{expandafter}}
+% \changes{v1.01}{1996/07/06}{\cs{@iforl@@p} replaced by
+% a LaTeX2e-like definitiion}

+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+%
+% The macro |\@m@mb@r| separates a character string into to portions
+% by using a double equality symbol (|==|) and a semicolon as delimiters.
+% The first potion consists of a locant number and a bond modifier (stored
+% in |\@membera|), which are further separated by the macro |\twoch@r|,
+% |\twoch@@r| or |\threech@r|.
+% The second potion shows a substituent (stored in |\@memberb|),
+% which is printed by means of an appropiate command.
+%

+% \end{macro}
+%
+% The following two commands are added to treat spiro fusion.

+%
+% \subsection{Conventions}
+%
+% Switches for characterizing substitution sites as
+% left, right or left-right boxes become effective in
+% the commands |\putlatom|, |\putratom| and |\putlratom|.
+% They are used for warning wrong or unnecessary usages of
+% |\lmoiety| or |\rmoiety|.

+%
+% We can use the macro |\rmoiety| for drawing a right-hand substituent
+% and the macro |\lmoiety| for drawing a left-hand substituent.
+%
+% \changes{v1.02}{1998/10/20}{The definitions of \cs{rmoiety} and
+% \cs{lmoiety} are changed. Warning function is added.}
+%
+% When you use a |\rmoiety| command in a left box produced by
+% a |\putlatom| command, the warning ``Wrong |\rmoiety|'' is reported.
+% When you use a |\lmoiety| command in a right box produced by
+% a |\putratom| command, the warning ``Wrong |\lmoiety|'' is reported.
+% If the ``draft'' option is effective, these cases are designated by
+% solid squares at the corresponding positions on pages.

+% \subsection{Placing substituents for vertical formulas}
+%
+% Such a drawing command as |\setsixringv| uses several inner macros
+% for placing substituents with bonds. The first set of inner macros
+% are shown as follows.
+%
+% The command |\ylposition| is to obtain the shift values

+% point of a substituent.
+% The locant flags such as |\@ylatrue| have been stoped to use.

+%
+% Such a drawing command as |\setsixringh| uses several inner macros
+% for placing substituents with bonds. The first set of inner macros
+% are shown as follows.

+% \subsection{Setting-up substituents and bonds on a six-membered ring}
+%
+% The |\setsixringh| macro takes 5 arguments, which have the same meanings
+% as described in the definition of the |\setsixringv| macro.
+%
+% \begin{verbatim}
+% ****************************************************************
+% * setting of atoms and bonds on a horizontal six-membered ring *
+% ****************************************************************
+%
+% \setsixringh{SUBSLIST}{AD}{LOWER}{UPPER}{ORDER}
+%
+% \end{verbatim}
+%
+% The first argument |SUBSLIST| is a list of substituents, which is
+% represented in the standard format of \XyMTeX{}.
+%
+% \begin{verbatim}
+% SUBSLIST: list of substituents (max 6 substitution positions)
+%
+% for n = 1 to 6
+%
+% nD : exocyclic double bond at n-atom
+% n or nS : exocyclic single bond at n-atom
+% nA : alpha single bond at n-atom
+% nB : beta single bond at n-atom
+% nSA : alpha single bond at n-atom (boldface)
+% nSB : beta single bond at n-atom (dotted line)
+% nSa : alpha (not specified) single bond at n-atom
+% nSb : beta (not specified) single bond at n-atom
+%
+% nSd : alpha single bond at n-atom (dotted line)
+% with an alternative direction to nSA
+% nSu : beta single bond at n-atom (boldface)
+% with an alternative direction to nSB
+% nFA : alpha single bond at n-atom (dotted line)
+% for ring fusion
+% nFB : beta single bond at n-atom (boldface)
+% for ring fusion
+% nGA : alpha single bond at n-atom (dotted line)
+% for the other ring fusion
+% nGB : beta single bond at n-atom (boldface)
+% for the other ring fusion
+%
+% \end{verbatim}
+%
+% The second argument |AD| is an adjustment value, which adjusts the original
+% set of locant numbers into the standard one between 1 to 6 for drawing
+% a six-membered ring.
+% The effective range of the standared set of locant numbers is
+% restricted by the auguments |LOWER| and |UPPER|. A minus value of
+% the last argument shows the anti-clockwise numbering, while zero or
+% a plus value represents the clockwise numbering.
+%
+% \begin{verbatim}
+% AD : adjustment e.g. 0 for six-membered rings
+% LOWER : lower limit LOWER < effective range < UPPER
+% UPPER : upper limit
+% ORDER : >= 0 clockwise, <0 anti-clockwise
+%

+% \subsection{Basic Commands for Six-Membered Rings}
+%
+% For treating spiro-ring fusion, the following basic commands
+% (|\test@vertix| and |\test@vertix@sixv|) are added at the
+% time of releasing Version 2.00. These commands are generally
+% used for detecting hetero atoms at respective vertices of a
+% heterocyclic ring.
+%
+% The command |\test@vertix| is used in |\test@vertix@sixv|.
+% which is designed to test the existence of a hetero atom
+% (or an equivalent) at each vertix of a six-membered ring.
