%%%                        for University of California Ph.D. dissertations.
%%%            It is a direct port to LaTeX2e from UCTHESIS
%%%            v2.7 by Ethan V. Munson, with no changes other 
%%%            than those for compatibility.  The major modifictions
%%%            are in the font selection commands in the option
%%%            files uct1x.clo.
%%%            
%%%            UCTHESIS.STY v2.7 is based on the standard
%%%            report.sty as modified by Mittelbach and Schopf in
%%%            Jan 1992.  The primary differences are (1) the use
%%%            of pseudo-double-spacing, except in certain special
%%%                        environments; and (2) the use of a 6 inch line
%%%                        with 4em paragraph indentation.  It is only
%%%            intended for single-sided printing.  Double-sided
%%%            printing may be possible, but you're on
%%%            your own.
%%%
%%%                        I know of no bugs in this implementation,
%%%                        but would be happy to hear of any problems
%%%                        that arise with it.
%%%
%%%            Version 2.x fixes a bug in the previous
%%%            version of 20 Jun 1988.  The bug was that 
%%%            "draft" optional mode didn't work because of
%%%            problems in handling optional arguments.
%%%                        This file does not seem to work with earlier 
%%%                        versions of LaTeX (pre-Jan 1992).
%%%
%%%            Version 2.3 includes a single-spaced 
%%%            tabular* environment.
%%%         
%%%            Version 2.4 sets \evensidemargin correctly
%%%            for two-sided style.  It also adds new
%%%            environments (\smalltabular and
%%%            \scriptsizetabular) which produce tables
%%%            with smaller fonts.  The obvious methods
%%%            of producing small-font tables don't work
%%%            in ucthesis style.
%%%
%%%            Version 2.5 adds support for the \maketitle
%%%            macro.
%%%
%%%            Version 2.6 adds support for complete and
%%%            correct front matter.  Some dead code was
%%%            removed, too.
%%%
%%%                        Version 2.7 adds front matter support for
%%%                        thesis committees of more than 3 people
%%%                        and for a labeled signature line on the
%%%                        abstract page.
%%%
%%%            Version 3.0 is a direct port of version 2.7
%%%            to LaTeX2e.  The major revisions in ucthesis.cls
%%%            are converting option processing to LaTeX2e 
%%%            conventions.  The uct1x files have been revised
%%%            to use the new font selection commands.
%%%
%%%            Some users have had problems with the 
%%%            margins ending up too small on one side.
%%%            This appears to be a DVI-to-PostScript
%%%            driver or printer-adjustment problem.
%%%            If you have such trouble, make small adjustments
%%%            to the \textwidth and \oddsidemargin
%%%            settings in your document preamble.
%%%            
%%%            Another problem some people have had is
%%%            that you can't use \pagestyle{headings}
%%%            and \markboth if you use \part.  The solution
%%%            is to get the headerfooter style, which is
%%%            nice and simple to use."

% Option values are now declared first thing.  Defaults are set to
% 11 point, onesided, final (ie not draft) mode (BBF 10/31/94)
\newcommand\@ptsize{}
\newcommand\@draftmark{}
\DeclareOption{10pt}{\renewcommand\@ptsize{0}}
\DeclareOption{11pt}{\renewcommand\@ptsize{1}}
\DeclareOption{12pt}{\renewcommand\@ptsize{2}}
\DeclareOption{oneside}{\@twosidefalse \@mparswitchfalse}

\ExecuteOptions{11pt,oneside,final}


% CHOOSING THE TYPE SIZE:
%
%  The type size option is handled by reading a different file for each
%  size, as follows, to define font size-specific commands:
%       10pt : UCT10, 11pt : UCT11, 12pt : UCT12
%

%  Two-side or one-side printing.
%
% \@twosidefalse               %  Default is one-sided printing.
\def\ds@twoside{\@twosidetrue  %  Defines twoside option.
           \@mparswitchtrue}   %    Marginpars go on outside of page.

% This is a tricky solution to a tough bootstrapping problem.  The
% "draft" option requires the definition of the \ssp macro.  However,
% the \ssp macro requires that the uct1?.clo file has been loaded.  This
% loading is done by the \@options command which also invokes the
% \ds@draft macro.  This was a cyclic dependency in the previous
% version.  To break this dependency, I have made \ds@draft set a marker
% which is later tested to determine whether to actually do the draft
% mode actions.
% 
% Ethan Munson (October 16, 1992)

% FMi 91/03/30: made twocolum.sty a file and twocolumn an option.

% RmS 91/10/15: moved actual reading of twocolumn.sty
%               to the end of this file.
\def\ds@twocolumn{\@twocolumntrue}

% The \ProcessOptions command causes the execution of every option command
% FOO which is declared and for which the user typed the FOO option in his
% \documentclass.  For every undeclared option BAR there will be a warning 
% message. (BBF 10/31/94)

% This document style is for documents prepared in the English language.
% To prepare a version for another language, various English words must

% APPROVALPAGE
%
% The \approvalpage macro emits a UC-approved approval page ready for
% your committee's signature.  It is not an automatic part of the 
% output because there's really no point in printing it until you are
% ready to get signatures.  It requires the the \year, \author, and
% \campus macros have been defined.  It uses lots of tricky spacing
% that is probably better handled with tabular environment code, but
% I'm too lazy to fix it. (EVM, 9/19/94)

%    ****************************************
%
% A \subsection command writes a
%       \contentsline{subsection}{TITLE}{PAGE}
% command on the .toc file, where TITLE contains the contents of the
% entry and PAGE is the page number.  If subsections are being numbered,
% then TITLE will be of the form
%       \numberline{NUM}{HEADING}
% where NUM is the number produced by \thesubsection.  Other sectioning
% commands work similarly.
%
% A \caption command in a 'figure' environment writes
%    \contentsline{figure}{\numberline{NUM}{CAPTION}}{PAGE}
% on the .lof file, where NUM is the number produced by \thefigure and
% CAPTION is the figure caption.  It works similarly for a 'table'
% environment.
%
% The command \contentsline{NAME} expands to \l@NAME.  So, to specify
% the table of contents, we must define \l@chapter, \l@section,
% \l@subsection, ... ; to specify the list of figures, we must define
% \l@figure; and so on.  Most of these can be defined with the
% \@dottedtocline command, which works as follows.
%
% \@dottedtocline{LEVEL}{INDENT}{NUMWIDTH}{TITLE}{PAGE}
%    LEVEL    : An entry is produced only if LEVEL < or = value of
%               'tocdepth' counter.  Note, \chapter is level 0, \section
%               is level 1, etc.
%    INDENT   : The indentation from the outer left margin of the start
%               of the contents line.
%    NUMWIDTH : The width of a box in which the section number is to go,
%               if TITLE includes a \numberline command.
%
% This command uses the following three parameters, which are set
% with a \def (so em's can be used to make them depend upon the font).
%   \@pnumwidth : The width of a box in which the page number is put.
%   \@tocrmarg  : The right margin for multiple line entries.  One
%                 wants \@tocrmarg > or = \@pnumwidth
%   \@dotsep    : Separation between dots, in mu units.  Should be
%                 \def'd to a number like 2 or 1.7

%        effectively inside a \parbox of width \columnwidth (i.e., with
%        \hsize = \columnwidth).
%
%        The following macro indents all lines of the footnote by 10pt,
%        and indents the first line of a new paragraph by 1em.  To
%        change these dimensions, just substitute the desired value for
%        '10pt' [in both places] or '1em'.  The mark is flushright
%        against the footnote.

%
%        A simpler macro is used, in which the footnote text is
%        set like an ordinary text paragraph, with no indentation except
%        on the first line of a paragraph, and the first line of the
%        footnote.  Thus, all the macro must do is set \parindent
%        to the appropriate value for succeeding paragraphs and put the
%        proper indentation before mark.

% To define a float of type TYPE (e.g., TYPE = figure), the document
% style must define the following.
%
%  \fps@TYPE   : The default placement specifier for floats of type
%                TYPE.
%
% \ftype@TYPE : The type number for floats of type TYPE.  Each TYPE
%                has associated a unique positive TYPE NUMBER, which
%                is a power of two.  E.g., figures might have type
%                number 1, tables type number 2, programs type number
%                4, etc.
%
% \ext@TYPE : The file extension indicating the file on which the
%                contents list for float type TYPE is stored.  For
%                example, \ext@figure = 'lof'.
%
%  \fnum@TYPE  : A macro to generate the figure number for a caption.
%                For example, \fnum@TYPE == Figure \thefigure.
%
%  The actual float-making environment commands--e.g., the commands
%  \figure and \endfigure--are defined in terms of the macros \@float
%  and \end@float, which are described below.
%
% \@float{TYPE}[PLACEMENT] : Macro to begin a float environment for a
%     single-column float of type TYPE with PLACEMENT as the placement
%     specifier.  The default value of PLACEMENT is defined by
%     \fps@TYPE.  The environment is ended by \end@float.  E.g.,
%     \figure == \@float{figure}, \endfigure == \end@float.

%    ****************************************
%
% The page style 'foo' is defined by defining the command \ps@foo.  This
% command should make only local definitions.  There should be no stray
% spaces in the definition, since they could lead to mysterious extra
% spaces in the output.
%
% The \ps@... command defines the macros \@oddhead, \@oddfoot,
% \@evenhead, and \@evenfoot to define the running heads and
% feet---e.g., \@oddhead is the macro to produce the contents of the
% heading box for odd-numbered pages.  It is called inside an \hbox of
% width \textwidth.
%
% To make headings determined by the sectioning commands, the page style
% defines the commands \chaptermark, \sectionmark, ... , where
% \chaptermark{TEXT} is called by \chapter to set a mark, and so on.
% The \...mark commands and the \...head macros are defined with the
% help of the following macros.  (All the \...mark commands should be
% initialized to no-ops.)
%
% MARKING CONVENTIONS:
% LaTeX extends TeX's \mark facility by producing two kinds of marks
% a 'left' and a 'right' mark, using the following commands:
%     \markboth{LEFT}{RIGHT} : Adds both marks.
%     \markright{RIGHT}      : Adds a 'right' mark.
%     \leftmark  : Used in the \@oddhead, \@oddfoot, \@evenhead or
%                  \@evenfoot macro, gets the current 'left' mark.
%                  Works like TeX's \botmark command.
%     \rightmark : Used in the \@oddhead, \@oddfoot, \@evenhead or
%                  \@evenfoot macro, gets the current 'right' mark.
%                  Works like TeX's \firstmark command.
% The marking commands work reasonably well for right marks 'numbered
% within' left marks--e.g., the left mark is changed by a \chapter
% command and the right mark is changed by a \section command.  However,
% it does produce somewhat anomalous results if two \bothmark's occur on
% the same page.
%
%
% Commands like \tableofcontents that should set the marks in some
% page styles use a \@mkboth command, which is \let by the pagestyle
% command (\ps@...)  to \markboth for setting the heading or
% \@gobbletwo to do nothing.
