% 2010-12-07 Don't redefine \hline in table environment %
% for preprint or vanilla modes (John Edmiston) %
% 2.1.3 %
% 2010-11-11 Constrained smaller Summation to Istyle only %
% 2.1.2 %
% 2010-05-13 Fixed \parindent in two-column table environment %
% (thanks to Phil Bentley) %
% 2.1.1 %
% 2009-05-11 Added new paper category ST (running heads) %
% 2.1 %
% 2007-05-15 Added some new paper categories (running heads) %
% 2007-04-05 Added null multicols call to definition of \section %
% in preprint style (stops page running long); %
% fixed bug in \pdfbookmark calls to sections in %
% Appendices in IT style; %
% added optional argument to \aufn allowing multiple %
% footnote symbols to share same text, thanks to %
% Christian Biertuempfel %
% 2.0 %
% 2005-07-13 Released upon publication of Volume G %
% 2.0beta16 %
% 2005-07-05 Added \smallitcifname; changed the cifdefblock and %
% related macros to improve space management %
% 2005-06-29 Translated esd-su in \itemtypeconditionscode %
% 2005-06-23 Small tweak to placement of figure caption. %
% 2005-05-31 Tweaked \caption in IT tables for right font family %
% 2.0beta15 %
% 2005-01-07 Further fine tuning of cif dictionary macros %
% 2004-11-26 Began fine tuning cif dictionary macros %
% 2004-09-09 Fixed bug that lost 'A' in appendix section headings %
% with the boldsection option %
% 2004-08-12 New wording in parent/child CIF dictionary term %
% 2004-08-10 New option 'boldsection' for alternative style of %
% (sub)section headings in some Int. Tables volumes %
% 2004-07-06 Introduced example environment (similar to figure) %
% for International Tables G %
% 2004-05-19 Began to introduce some macros for Acta F %
% 2004-05-06 Allowed multiple correspondence addresses %
% 2004-04-21 Suppressed the macro version footline for IT %
% 2004-04-20 Introduced \footnotes (which draws the rule), \fnmark %
% and \fntext for manual placement of single-column %
% footnotes in the multicolumn environment. The %
% affiliationnote environment (intended primarily for %
% International Tables) is an alternative for a footnote%
% with no identifying mark %
% 2.0beta14: changes for International Tables production %
% 2004-01-12 Fixed punctuation in \ref calls; thanks to Christian %
% Anders Cumbaa; modified the environments table and %
% figure to allow an optional overriding numbering - %
% replaces the [caption] hack of beta12 and is necessary%
% for correct \ref strings %
% 2004-01-09 Began modifying page layout %
% 2.0beta13: changes for new conference abstracts style %
% 2.0beta12: changes for International Tables style %
% 2003-10-25 New command \backmatter for unnumbered final sections %
% 2003-10-21 Swapped order of running heads %
% 2003-10-19 Modified \caption in Int. Tables style to print %

% 2003-06-30 Bugfix to handle \pdfbookmark if the \hyperref %
% package hasn't been invoked. Thanks to Loic Bertrand %
% 2.0beta10 %
% 2002-12-11 Allowed keywords option in Acta conference style %
% 2.0beta9 %
% 2002-10-09 Added category SG (structural genomics papers) %
% 2002-10-28 Modified textheight in IT style from 254 to 260mm %
% 2.0beta8 %
% 2002-04-11 Backed out RequirePackage{html}: not reqd in TeXLive6 %
% 2002-01-09 Backed out the inclusion of \bgroup and \egroup in %
% the redefined \mathbf. The problem is that there is a %
% conflict in standard LaTeX between the scope of \bf %
% and \mathbf, yet \bf in math mode calls upon the %
% \mathbf macro construction. It may be best later to %
% remove the \mathbf redefinition altogether %
% 2.0beta7 %
% 2002-01-08 Added \DeclareMathSymbol{/} for bold solidus %
% 2001-12-14 Fixed scoping problem in redefined \mathbf. Thanks to %
% Gunnar Thorkildsen %
% Changed some comments; thanks to Chris Cousins %
% 2.0beta6 %
% 2001-10-25 Added RequirePackage{html} ahead of %
% RequirePackage{harvard} to cure dependency problems %
% of these two packages that call each other %
% 2.0beta5 %
% 2001-06-20 Major revamp of all styles to weed out bugs %
% 2001-06-14 New vanilla style introduced for general purposes %
% 2001-06-12 New styles introduced for Acta C and Acta E %
% There is a problem with the footer on the last page %
% of a conference paper if that page is full: the page %
% is ejected with the standard footer before the %

% This is eqalign.tex in text format as of 30 July 1987.
% The following definition is straight from PLAIN.TEX
% This file exists as a LaTeX style option to enable users to
% put back something that LaTeX removed from PLAIN but which
% is sorely missed by people who write long equations.
% You should be able to add 'eqalign' to the options list in square
% brackets which specifies the options of any standard LaTeX style.
% This file may also be input into a STY file e.g. the LEPNOTE style
% option includes it automatically.
% Do not attempt to input it anywhere in a LaTeX document.
\def\eqalign#1{%
\null\,\vcenter{\openup\jot\m@th
\ialign{\strut\hfil$\displaystyle{##}$&$\displaystyle{{}##}$\hfil
\crcr#1\crcr}}\,}
% \eqalign works inside $$ ... $$ or \[ ... \] in LaTeX thanks to the
% above restoration. This should help remedy the deficiencies of
% the eqnarray environment for long expressions.
% It seems to work also in the equation environment if you put
% the \label command inside an \hbox.
% This seems to resolve a problem with math glue from \eqalign mixing
% with ordinary glue generated by \label. God help us.
% Use of \eqalign is explained in the TeXbook.

% First, some fairly hairy font stuff, based originally on the mathptm
% package by S. Rahtz, distributed as part of standard LaTeX. Declare the
% standard PostScript fonts for use in equations, but prefer Computer
% Modern for symbols and Greek lower-case letters, which we need in a
% slanted form. Sometimes we need bold Greek lowercase letters. We achieve
% this in two ways: the \SetSymbolFont{greek}{bold} makes Greek letters
% bold when \mathversion{bold} is declared (this is used e.g. to make a
% formula bold within a heading or title). We also define individual
% symbols (e.g. \bfalpha) to obtain bold single letters. This is compatible
% with the practice in the iucmac plain TeX macro package. However, it
% introduces non-standard macro names which we prefer not to inflict upon
% authors. So instead we redefine the standard \mathbf to change every Greek
% symbol macro name to its bold equivalent.
