+% 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, 18, 109--116 (1994). 
+% The following book deals with an application of TeX/LaTeX to 
+% preparation of manuscripts of chemical fields:
+%  (2)  Shinsaku Fujita, ``LaTeX for Chemists and Biochemists'' 
+%    Tokyo Kagaku Dozin, Tokyo (1993) [in Japanese].

+%    formulas'', TUGboat, 16(1), 80--88 (1995).
