% 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 %
% AtEndDocument comes into effect. For now, we leave %
% this because conference papers will usually be run %
% with the nohead option anyway %
% 2.0beta4 %
% 2001-06-12 New style introduced for JSR; old style renamed x; %
% option nohead introduced for JSR to omit headers and %
% footers in camera-ready contributions %
% 2.0beta3 %
% 2001-04-05 some small mods to CIF macros for ITVG %
% 2000-10-10 default LaTeX \index commands reinstated in it style %
% 2.0beta2 %
% 2000-04-06 fixed single-line fig captions, conference r/head %
% 2000-02-08 modified \thebibliography to include heading for [a,d]%
% 1999-12-16 added \pdfbookmark to section definitions (pdflatex) %
% 2.0beta1 %
% 1999-12-10 preprint style simplified: no r/heads, wider margins %
% 1999-12-07 new journal styles introduced as option a; old style %
% renamed as option o %
% 1.0 %
% 1999-07-01 twoside option reintroduced to article base class %
% 1999-06-04 bold upright Greek font descriptions introduced %
% 1999-05-15 version released as 1.0 %
% beta-4 %
% 1999-05-15 some more small improvements; release version %
% 1999-05-14 some small bugfixes and improvements; \PDBref and %
% \NDBref added for Acta D papers; awkward positioning %
% of footnotes on first page of new-style Acta articles %
% achieved %
% 1999-05-13 full articles and short contributions working %
% 1999-05-11 some minor style mods to D/conference style %
% 1999-05-07 first working version of conference style %
% 1999-05-06 began work on Acta D/SAS conference style %
% beta-3 %
% 1999-05-04 bugfix: _ in ciflisting environment redefined as %
% \char'137{} (with trailing {} to prevent collision %
% with following material) %
% 1999-04-01 bugfix: \journalreceived failed for e.g. 11 May %
% 1999-03-09 cif macros modified so that underscore can be used %
% in \ref and other places (thanks to Thomas Proffen) %
% 1999-03-01 \section now uses standard \@startsection directives %
% (with \global\@afterindentfalse to cancel indent of %
% first paragraph) %
% 1999-02-10 macros added for typesetting CIF listings and CIF %
% dictionary entries %
% 1999-02-04 `raggedstyle' conditional introduced for subject %

% 1998-11-18 Organic, Inorganic index categories for Acta C %
% 1998-11-09 Bugfix to catchline for Acta C %
% 1998-11-05 Made \journal... and \paper... macros preamble only %
% 1998-11-03 Added 4th and 5th level sections to IT %
% 1998-10-28 Font work: Times allowed in equations, sloping Greek %
% and bold Greek handled OK %
% 1998-10-27 first pass at an International Tables style: page %
% size and gross style elements %
% 1998-10-26 index environment introduced; catchline built up %
% in a box (not on the fly as before) %
% beta-2 %
% 1998-09-08 thebibliography environment modified following %
% Matt Newville [email protected]; originally %
% \referencelist was a wrapper for \bibliography that %

% 1998-09-04 Added preprint style %

%#############################################################################
% 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.

% ====================== main code ===========================================
% 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.
