%%% names in documents to be numbered and does not
%%% affect the normal citation routines.
%%% Very helpful for writing chemistry papers.
%%% This style does:
%%% - Compound-numbering. Any compound gets a number
%%% using \fcite, bold face as default. This number
%%% is printed every time you type \fcite.
%%% - The compounds are numbered according to the
%%% entries in the \theffbibliography.
%%% - The \ffbibliography generates an chapter with
%%% the heading 'Compound numbers'.
%%% See comments and examples below.",
%%% }
%%% ====================================================================
%
% HISTORY:
%
% Writing chemistry papers, very often a consecutive numbering for compounds
% according to their appearance in the text is required. First, I have no
% knowledge of any basic Tex. I extracted the definitions for \cite and
% \thebibliography from latex.ltx and article.cls and replaced every
% occurrence of the string cit by ffcit
% and bib by ffbib. In addition, I also performed some small formatting
% changes. Thus, this package worked nicely
% in a document with 300 compound numbers and 700 citations in latex209 and latex2e.
%
% Version 1.0
% Latex209.
%
% Version 1.1
% Same thing for Latex2e.
%
% Version 1.2
% Now works with Latex2e of 1996/06/01
%
% Version 1.3
% Added option [tight]. Saves space in the compound number list. Default is [normal].
%
% USAGE:
% Load package chemcono. For every compound, use \fcite like \cite for citations.
% After a \clearpage at the end of your document use theffbibliography like
% the normal thebibliography, with \ffbibitem instead of \bibitem:
% \begin{theffbibliography}{99}
% \ffbibitem{f1} danaidone
% \ffbibitem{f2} thio ether
% \end{theffbibliography}
% After compilation and printout, discard the last page.
% If you want other formatting than bold face numbers, use
% \renewcommand{\fcite}[1]{\underline{\ffcite{#1}}}
% which gives in this case an underlined number.
% Look at example.tex.
% The formatting of the ffbibliography can be made tight to save space by the option [tight].
%
% I have added the file drftcono.sty, which bases on the drftcite.sty file from D. Arseneau.
% When using drftcono.sty, you get the tags of the compound numbers instead the real numbers in the text.
% In the compound number section, small superscripts show which label has been used first, second,
% and so on. You have to load drftcono.sty after chemcono.sty. For the final version, just comment
% out drftcono.sty as in example.tex.
% I also added a file showkeysff.sty, which shows labels in the margin as in showkeys, but the \fcite tags
% are also added. I was not able to include counting of occurrence present in drftcono
% in the showkeysff package, which would be highly desirable.
%
%
% COMPLICATIONS:
% You must not use identical labels for \fcite and \cite. Otherwise Latex gets
% confused. As a hint, I identify every compound label by a preceding f as in
% \fcite{f1}, and every citation label with a c, like \cite{c1}.
%
% FUTURE:
% I would like to have the option for removing the printout of
% theffbibliography. Than one would not need to discard the last page.
% Because I have no knowledge of any programming, I do not know how to do
% this. I also do not know whether the goal of this style could be achieved
% much more easily. Any hints are welcome.
% Inclusion of order of occurrence counting in showkeysff.
