% We start out with the standard LaTeX document class "article" or "report" and
% modify it so it conforms to the Sandia Technical report style.
% The modifications are based on "Guide to Preparing SAND Reports",
% SAND98-0730, edited by Tamara K. Locke, and the newer "Guide to
% Preparing SAND Reports and Other Communication Products", SAND2002-2068P.

%
% Rolf Riesen, September 19, 2006.
%
%
% 06/14/2002 v1.01
%     Make distribution list wider. Spaces between area codes and phone numbers
%
% 06/17/2002 v1.02
%     Use \raggedright for main title
%
% 06/19/2002 v1.03
%     Set tocdepth to 2 to only list sections and subsections in TOC
%
% 08/07/2002 v1.04
%     Added a Makefile based on one Mike Heroux provided
%     Allow for distribution lists that span more than one page and
%     typeset the distribution in two columns
%
% 11/25/2002 v1.05
%     Some changes from Daniel Segalman to conform to the new guide
%     (SAND2002-2068P):
%     - Adjust top margin of the title page to conform to the MS Word
%         template (this may or may not be correct depending on your
%         latex/dvips initial setup. Use texconfig to setup paper and
%         dvips).
%     - Added the word "Printed" before the date on front page
%     - Classification category is no longer needed on page 3; get
%         rid of \SANDdistcategory
%     - Added "National Nuclear Security Administration" on title page
%     - Changed NTIS URL on page 2
%
%     If "strict" is not used, we'll number sections to two decimal
%     places (1.2.3)
%
% 02/13/2003 v1.06
%     New DOEbwlogo.eps from Tim Draelos. This one is smaller and has some
%     incompatible junk removed.
%
% 10/16/2003 v1.7
%     Using \ifthenelse in the addcontentsline command interfered with
%     the subfigure class. James Gruetzner and Todd Pitts provided a fix.
%
%     Philippe Pebay reports that the color package needs to be imported
%     before the graphicx package. This class file uses the graphicx package,
%     so Philippe could not use the color package because graphicx was already
%     loaded when his \usepackage command got executed.
%
% 11/19/2003 v1.8
%     Make it work using the report class. Put "report" as an option into
%     \documentclass[report]{SANDreport} to activate it. There were some other
%     fixes and clean-up s as well. Mainly in the table of contents.
%     - Changed NTIS URL on page 2
%     - Added fleqn to \LoadClass
%     - Can't get the report title to repeat on the first chapter page.
%         Left it off for now.
%     - The table of contents formatting for report class is more or less like
%         report.cls. For article, we try to make it look like the guideline.
%
% 01/19/2004 v1.9
%     - The distribution list at the end of a SAND report was modifying the
%         description environment which interfered with its regular use. Created
%         a separate environment to fix that.
%     - If in "report", list chapters and sections in TOC
%     - With the jpg option, load the jpg versions of the DOE and Sandia
%         logos. This makes it possible to use pdftex which doesn't
%         understand Postscript.
%
% 02/25/2004 v1.10
%     - It is now SANDIA REPORT, no longer SAND REPORT. Central Technical Files
%         now wants three copies. See the distribution examples. (Info from
%         Philippe Pebay)
%     - Added new commands for markings used in OUO, export controlled, and
%         other reports not labeled "Unlimited Release". Thanks to Mark
%         Ackermann for providing an OUO example.
%     - In report style, the page numbers restarted after the title page. Fixed!
%     - Big clean-up.
%
% 05/14/2004 v1.11
%     - Had to comment out a line in fancyhdr.sty for pdflatex to work.
%         Don't know why.
%
% 05/21/2004 v1.12
%     - Added the options [FIGBOTCAP,normal,bf,tight] to the subfigure
%         package in the example files from a suggestion by Philippe P. Pebay.
%     - Added the CA and NM options to insert the respective standard distributions.
%
% 08/07/2004 v1.13
%     - Use pdf versions of logos. Makes the "jpg" option obsolete. Suggestion
%         and logos by Richard Lehoucq.
%     - Making SANDreport.cls compatible with the hyperref package
%     - Added SANDmath.tex from Philippe Pebay
%
% 08/18/2004 v1.14
%     - \begin{SANDdistribution} now takes an optional argument (CA or NM). The
%         respective \documentclass options are no longer valid. Several new
%         commands are available within the SANDdistribution environment to
%         automate distributions for special cases such as CRADA, LDRD,
%         Classified, Patent, etc.
%     - The distribution list is now better formatted.
%     - Fixed a bug with \SANDreleaseType discovered by Mark Ackermann
%     - Added the command \SANDmarkTop
%
% 05/20/2005 v1.15
%     - A small change in the distribution list (D. Chavez in the LDRD office
%         moved) Thanks to Brandon Rohrer.
%
% 12/05/2005 v1.16
%     - New org numbers reflect new corporate structure 9616->4536, etc. Thanks
%         to Philip Sackinger for doing this.
%     - Philip also found out what the newest distribution rules for NM are.
%     - In the example files, deleted a misleading comment about secnumdepth in
%         the appendix. Thanks to John Mitchell for spotting this.
%     - New SANDmath.tex from Philippe Pebay: (ver. 1.2)
%         + add support for discrete intervals
%         + fix some comments
%         + replace incorrect \RequirePackage's by \usepackage'
%     - Also from Philippe Pebay: CA distribution list changes.
%     - Abstract will start on title page, even with report style. Thanks to
%         Daniel Dolan for noticing it and making suggestions to fix it.
%     - Put the title just above the first chapter in the report style
%
% 12/09/2005 v1.17
%    - Fixed a bug introduced in the last version: The \cleardoublepage is
%        only supposed to happen for chapters in the main body of a report,
%        and it needs to happen before the page number is entered into the TOC.
%    - Fixed several new and old bugs that dealt with markings
%    - Fixed text on usage page about marking commands.
%
% 12/09/2005 v1.18
%    - Make it work with hyperref again....
%
% 12/19/2005 v1.19
%    - There were still problems with the hyperref package. Fixed it so that
%        the page markings on the back cover are now correct.
%
% 12/21/2005 v1.20
%    - Updated the distribution list according to version 2.0 of the Guide
%
% 03/22/2006 v1.21
%    - Introduced \SANDrePrintDate and \begin{SANDreDistribution}
%    - Put a page number (2) on the back cover
%    - No institution in \SANDauthor{} in example files
%    - Move the SNL logo on the cover towards the bottom of the page
%    - Add a back cover with the SNL logo at the bottom of the back
%    - Use \cleardouble page and add comment to example files to make
%        sure TOC always starts on an odd page.
%    - Don't put title on first page of body text (above introduction)
%        anymore. (Changed from Ver 1.0, Sep. 2002 to Ver 2.0, Dec. 2005 of the guide.)
%    - For article, start every section on a new page (report already does this)
%    - Fixed URLs for DOE report ordering
%    - \SANDmarkCover now takes only one argument! This makes it easier to draw a
%        box around the statement and configure it as needed. See MarkOUO.tex for
%        an example. Thanks to John Foster for the example.
%    - Print small class file version number at bottom of inside back cover
%    - Change by Daniel Dolan to make it work and look consistent with the mathptmx
%        package. This leaves the Helvetica fonts on the cover alone, but lets him
%        have the body of the report in Times.
%    - From Debbie Johnson (Creative Arts):
%        - In example files, use First Name, Middle Initial, Last Name on cover and title page
%        - In example files, on cover, put author names on one line
%        - Mail Stop for Central Technical Files is MS9018. (This was an error in the example
%            file, not the class itself.)
%        - Back cover was shifted right too far.
%        - Move chapter headings up a bit.
%        - Use the geometry package to get the margins right
%
% 06/10/2006 v1.22
%    - Remove "Unclassified" from "Unclassified Unlimited Release" (Thanks Brett Bader and Mike Heroux)
%    - Confirmed that M2497 is correct mail stop for classified reports to Central Technical
%          Files. (Thanks Debbie Johnson)
%    - Make the distribution list single column. This makes it easier to print labels.
%    - D. Chavez, LDRD Office mail-stop changed from 0188 to 0123. (Thanks Brett Bader)
%    - In examples, added \phantomsection and moved \addcontentsline{toc}{section}{References}
%        just before the \bibliography{...} command. This helps putting the right page number
%        into the TOC and also with hyperlinking. (Thanks Tammy Kolda)
%    - Clarified usage of \SANDnum{} on Web page. (Thanks Tammy Kolda)
%    - More usage and LaTeX tips on Web page. (Thanks Tammy Kolda)
%    - Newer distributions have a fancyhdr.sty that works. Removed it.
%
% 06/26/2006 v1.23
%    - Tammy Kolda found a bug when using amsmath. Seems to have been a problem with
%        white space in the redefinition of \section. LaTeX would stop when building the TOC.
%
% 08/17/2006 v1.24
%    - Changed tar file extenstion from .tgz to .tar.gz Some winzip versions under
%        Windows don't seem to like the former. (Rich Lehoucq)
%    - Org. Number for Central Technical Files changed from 8945-1 to 8944 (Tammy and Debbie)
%
% 09/19/2006 v1.25
%    - David Wilson discovered that markings in report style also activated chapter
%        name headings, which are unwanted and sometimes overlap with the markings.
