% files ({\sf carom.sty} for the present case).  Hence, the combination 
% of |\input| and |\@ifundefined| is used to crossload sty

% |\RequirePackage| command of \LaTeXe{}.

% \subsection{Vertical cyclohexanes}
%
% The macro |\cyclohexanev| is used for drawing cyclohexane derivatives 
% of vertical type.  The skeleton and endocyclic double bonds are
% drawn directly, while substituents and exocyclic bonds are placed by 
% useing the inner macro |\setsixringv|.

% \begin{verbatim}

%
% The |SUBSLIST| argument contains one or more substitution descriptors

% \section{Benzene and benzoquinone derivatives}
% \subsection{Vertical type}
%
% The macro |\bzdrv| (|\benzenev|) is used for drawing benzene derivatives 
% of vertical type as well as benzoquinone derivatives of 
% vertical type. The skeleton and endocyclic double bonds are
% drawn directly, while substituents and exocyclic bonds are placed by 
% useing the inner macro |\cyclohexanev| defined above. 
% 
% The macro |\bzdrv| has an argument |SUBSLIST| as well as an optional 
% argument |OPT|.  The latter designates a bond pattern in place of  
% individual exocyclic bonds.

% \subsection{Steroids with a chain}
%
% The macro |\steroidchain| is used for drawing steroids.  
% 
% The macro |\steroidchain| has an argument |SUBSLIST| as well as an 
% optional argument |BONDLIST|.  
%
% \begin{verbatim}
% **************************************
% * steroid derivatives having a chain *
% **************************************
%  
%   \steroidchain[BONDLIST]{SUBSLIST}          
% \end{verbatim}
%
% The |BONDLIST| argument contains one or more 
% characters selected form a to t, each of which indicates 
% the presence of an inner (endcyclic) double bond on the corresponding 
% position. The character A, B, or C indicates an aromatic bond 
% pattern (circle).  A two-character string `Z?' indicates 
% a double bond in the side-chain. 
%
% \begin{verbatim}
%     BONDLIST = 
%
%       (double bonds for the steroid skeleton)
%           none:  no action on the steroid skeleton
%           a   :  1,2-double bond        b   :  2,3-double bond
%           c   :  3,4-double bond        d   :  4,5-double bond
%           e   :  6,5-double bond        f   :  6,7-double bond
%           g   :  7,8-double bond        h   :  9,8-double bond
%           i   :  9,10-double bond       j   :  1,10-double bond
%           k   :  5,10-double bond       l   :  9,11-double bond
%           m   :  12,11-double bond      n   :  12,13-double bond
%           o   :  14,13-double bond      p   :  8,14-double bond
%           q   :  14,15-double bond      r   :  15,16-double bond
%           s   :  17,16-double bond      t   :  17,13-double bond
%           A   :  aromatic A ring        B   :  aromatic B ring
%           C   :  aromatic C ring
% \end{verbatim}
%
% \begin{verbatim}
%       (double bonds for the side chain)
%           Z   :  no action
%          Za   :  17,20-double bond     Zb   :  20,22-double bond
%          Zc   :  22,23-double bond     Zd   :  23,24-double bond
%          Ze   :  24,25-double bond     Zf   :  25,26-double bond
%          Zg   :  25,27-double bond
% \end{verbatim}
%
%  For a two-character indicator, you should write the BONDLIST 
%  as, e.g.
%
% \begin{verbatim}
%              [b{Za}{Zc}...]
% \end{verbatim}
%
% The |SUBSLIST| argument contains one or more substitution descriptors 
% which are separated from each other by a semicolon.  Each substitution 
% descriptor has a locant number with a bond modifier and a substituent, 
% where these are separated with a double equality symbol. 
%
% \begin{verbatim}
%     SUBSLIST: list of substituents
