%% This program can be redistributed and/or modified under the terms
%% of the LaTeX Project Public License Distributed, available from the CTAN
%% archives; either version 1.1 of the License, or any later version.  
%% Most importantly, you may modify this file, but only if you rename it.
%%
%% This is a contributed file to the LaTeX2e system.
%%
%% This program consists of the files ascelike.cls and ascelike.bst
%%
%% -----------------------------------
%%
%% This document class produces manuscripts that roughly comply with
%% the guidelines of the American Society of Civil Engineers.  However,
%% it was not produced by ASCE, its agents, or employees; nor is it in
%% any way sanctioned or approved by that organization.
%%
%% -----------------------------------
%%
%% Please note the following usage:
%%
%%   1) This is a LATEX2E class file; it will not work with LaTeX 2.09.
%%
%%   2) It requires the following supplementary files:
%%        ifthen.sty    (part of the standard latex release)
%%        setspace.sty  (produces doubles spacing for journal manuscripts)
%%        endfloat.sty  (places figures and tables at the end of the manuscript)
%%        lineno.sty    (places line numbers alongside the text)
%%        authblk.sty   (collects the lists of authors and affiliations)
%%        biblatex.sty  processes citations and bibliographic entries
%%        babel.sty     required by biblatex
%%        newtxtext.sty approximations Times fonts
%%        newtxmath.sty approximations Times fonts
%%      Without these files, it won't work.  All of these files are included
%%      in modern distributions of LaTeX for Windows, Mac, and Linux sysgems.
%%      All of these files are also available from the CTAN archive, 
%%      currently at //http:www.tug.org/ctan.html
%%
%%   3) The following files can be used with the tool biber to produce 
%%      ASCE-like reference citations and entries (with the weird use of 
%%      quotation marks around titles, etc.)
%%        ascelike.bbx
%%        ascelike.cbx
%%        ascelike.bib  (an example bibliographic database for use with bibtex)
%%      Version 3.0 of asceline uses the "biblatex" and the "biber" helper
%%      program to process and format citations and bibliographic entries.
%%      Unfortunately, biblatex must be manually entered within the *.tex
%%      file, after the \documentclass line, as:
%%         \usepackage[backend=biber,uniquename=init,style=ascelike]{biblatex}
%%      Also, your bibliographic database is specified with the following
%%      command, for example:
%%         \addbibresource{ascexmpl.bib}
%%      Note the inclusion of the ".bib" suffix.  The following command places
%%      the reference section in your document:
%%         \printbibliography
%%      Finally, the biber helper program (not bibtex) to process the citations:
%%         biber <your tex file>.
%%
%%   3) There are several options.  The three main options are
%%         Journal, Proceedings, or Preprint:
%%         - "Journal" is the default format, and produces manuscripts intended
%%           for paper submissions to ASCE journals for review. The default
%%           settings of Journal are 12pt text, double-spaced text, numbered 
%%           lines, and in-text figures. These default settings can be altered 
%%           with the options that are described below.  The Journal option
%%           produces proper headings for sections, subsections, subsubsections,
%%           appendices, and the abstract, and it produces the proper page 
%%           margins and numbers the pages. Note that ASCE journals do not use
%%           numbered sections, subsections, or subsubsections.  This behavior
%%           can be changed with the \texttt{SectionNumbers} option.
%%         - "Proceedings" produces manuscripts for ASCE conference proceedings.
%%           As default settings, Proceedings uses single-spaced 12pt text,
%%           places figures and tables within the text, and does not number
%%           lines. All of these default settings can be altered with the 
%%           options that are described below. The Proceedings option produces
%%           proper headings for sections, subsections, subsubsections, 
%%           appendices, and the abstract.
%%         - "Preprint" produces an approximation of 2-column ASCE journal
%%           papers: single-space, 10pt, rules before and after the abstract,
%%           etc.  Using this options requires some manual adjustments of the
%%           *.tex file, as explained in the documentation, ascexmple.pdf
%%
%%       The remaining option override the defaults that are set by the
%%       above formats:
%%         - BackFigs or InsideFigs:
%%           These can be used to override the default placement of tables
%%           and figures for the Journal and Proceeding formats.
%%         - SingleSpace or DoubleSpace:
%%           These can be used to override the default text spacing for
%%           the Journal and Proceeding formats.
%%         - 10pt, 11pt, or 12pt:
%%           These can be used to override the default text size (12pt).
%%         - NoLists suppresses the inclusion of lists of figures and tables
%%         - NoPageNumbers suppressesthe printing of page numbers
%%         - SectionNumbers produces the numbering of sections and subsections,
%            unlike the ASCE convention.
%%
%% A few standard Latex options have been removed, as they don't seem to apply
%% in the ASCE environment: landscape, titlepage, openbib, leqno, fleqn
%%
%% As for preparing the document file: except for the new options, you
%% should just use standard sequencing of LaTeX commands.  
%%
%% The only new command that I've added is the \KeyWords command which 
%% prints your list of key words.
%%
%% Please contact Matthew Kuhn by email for suggestions, etc.
