% Noted modifications by Keith Farkas <farkas@eecg.toronto.edu> posted
% to comp.text.tex on 21 Apr 92 15:43:52 GMT:
% I have added a new vertical centering option to the slide style file
% writen by Yong Ryu. The new option is \vertgroup and is like \vertcenter
% with the exception that \vspace{2em} is placed after \subsection
% rather than \vspace{\vfill}.
%
% o  lslide.sty is a LaTeX/AmSLaTeX style file for
%       presentation slide typesetting.
%    It was developed for my personal use. That is,
%       it is a prototype. It may be improved in the future.
%       See Final Notes, Bugs, Comments, etc.
%
% o  It generates a title page, tables of contents,
%    separate section heading pages, and slides
%    with heads and foots inside a nice frame.
%
% o  No hyphenations:
%            Hyphenated words are not easily readable
%            in presentation slides, in my opinion.
%    No right-justifications
%            Right justifications may place too big spaces
%            between words, when hyphenations are turned off.
%
%    If you want hyphenations and/or right-justifications
%      go to the "defaults" section in the end of this style file
%      and comment commands to make them.
%
% o  A postscript driver is NOT required.
%                           ^^^
%
% o  Version 2.0.1 Update
%    A. added a third vertical centering option \vertgroup. \vertgroup
%       is like \vertcenter with the exception that \vspace{2em} is
%	placed after \subsection rather than \vspace{\vfill}.
%		Keith Farkas (farkas@eecg.toronto.edu April 21 1992)
%
% o  Version 2.0 Update
%    A. Frame macros are simplified and redundant macros are removed.
%    B. A bug in \slidecontents & \sectioncontents is fixed.
%       Bug: When filename.toc exists but is empty, the previous
%            version reports `\item ...' missing error.
%    C. Thanks to Tomoki Shiratori, an oval frame is added.
%    D. \typeA & \typeB are renamed to \vertcenter & \verttop.
%    E. \pframeA & \pframeB are renamed to \doubleboxframe & \shadowframe.
%    F. \sframeA & \sframeB are renamed to \boxsecframe & \shadowsecframe.
%
% o  Version 1.2 Update
%    A. A shadow page frame added.
%    B. \SFbox changed.
%    C. \vertcenter and \verttop def. changed.
%    D. Extra spaces following page no. in tables of contents are removed.
%
% o  Version 1.1 Update
%    A. Default page dimensions changed.
%    B. \leftmargini of itemize env.: \leftskip is always added.
%          The left skip of itemize env. is (almost) same as
%          that of enumerate env.
%    C. \SFbox added - places a shadow box.
%
% o  How to use it:
%    A. \documentstyle[12pt,lslide]{article}   % <- Minimal Req.
%       \documentstyle[12pt,amssymbols,lslide]{article}
%                             % <- use amssymbols.sty for LaTeX if available
%       \documentstyle[12pt,amstex,amssymb,lslide]{article}
%                             % <- may be used with AmSLaTeX
%                             % Personally, I prefer it because it can
%                             % easily handle various shapes/styles of fonts.
%
%       Or you may use art11.sty to make the whole slide fonts smaller.
%        \documentstyle[11pt,lslide]{article}
%        \documentstyle[11pt,amssymbols,lslide]{article}
%        \documentstyle[11pt,amstex,amssymb,lslide]{article}
%       (To make fonts smaller, you may also use \smallerfonts. See B.)
%       Note: There is no font size difference between art10.sty
%             and art11.sty, when fonts >= \large are used.
%             If you use art10.sty, head and foot fonts of slides
%             become too small.
%
%    B. \portrait (default)
%       \landscape
%           (Should be placed before \begin{document})
%       If your print driver allows the 90 degree rotation of the
%       output pages:
%          e.g., emTeX drivers - /tr1 or /tr3
%                 e.x.,  hp myslide /tr1
%          e.g., dvi2ps -  -elandscape   (???)
%       or your printer has a sideway printing mode,
%       you may use \landscape.
%
%      Probably, you must modify the page dimensions.
%      Place those modifications after \portrait or
%      \landscape. If you use the default (i.e., do not
%      use \portrait or \landscape), place them just after
%      \documentstyle[...]{...}.
%      e.g., \addtolength{\textwidth}{...in}
%            \addtolength{\textheight}{...in}
%            \addtolength{\topmargin}{...in}
%            \addtolength{\oddsidemargin}{...in}
%            \addtolength{\evensidemargin}{...in}
%
%       \defaultskip=...in or ...pt or ...em or ......
%         horizontal spaces at the left and the right of slide
%         bodies (within the slide frame)
%         The default is:
%             \defaultskip=1em
%
%       \vertcenter (default)
%       \verttop
%           (Should be placed before \begin{document})
%       \vertcenter option places \vspace*{\fill} on the top and bottom
%       of each slide page and after \subsection. (Vertical centering)
%       \verttop option places \vspace*{.5em} before \subsection and
%       \vspace*{1em} after \subsection; not \vspace on the top
%       or bottom of each slide page.
%       \vertgroup is like \vertcenter but places \vspace{2em} after
%	\subsection
%
%       \doubleboxframe
%       \shadowframe (default)
%           (Should be placed before \begin{document})
%       \doubleboxframe option places double boxes around each page.
%       \shadowframe option places a shadow box around each page.
%       \ovalframe option places an oval around each page.
%
%       \boxsecframe
%       \shadowsecframe (default)
%           (Should be placed before \begin{document})
%       \boxsecframe option places a single box around subsection title.
%       \shadowsecframe option places a shadow box around subsection title.
%
%       \contentsname{...}
%           (Placed before or after \begin{document})
%         Heading of tables of contents. Default is:
%            \contentsname{CONTENTS}
%
%       \smallerfonts
%           (Placed before \begin{document})
%         Make fonts smaller thoughout the whole file.
%         If you think the default fonts are too big,
%            use this command.
%         Or, you may use art11.sty to make fonts smaller. (See A.)
%
%       \smallcontentsfonts
%           (Placed before or after \begin{document})
%         Makes fonts for tables of contents smaller.
%         Use when the table of content occupies more than one page.
%         If it is used with \smallerfonts, it must placed after
%            \smallerfonts.
%
%    C. \title{T} or \title[T1]{T2}
%           (Placed before or after \begin{document})
%         T or T2 goes to the title page.
%         T or T1 goes to the left head of each page.
%       \author{A}
%           (Placed before or after \begin{document})
%         A goes to the title page and left foot of each page.
%       \organization{O}
%           (Placed before or after \begin{document})
%         O goes to the title page.
%       \date{D}
%           (Placed before or after \begin{document})
%         D goes to the title page.
%       \titlepage
%           (Placed after \begin{document})
%         Generates the title page.
%
%    From now on, everything should be placed after \begin{document}
%
%    D. \slidecontents or \slidecontents*
%           (Placed outside \begin{slide} ... \end{slide})
%         Generates a Table of Contents that Consists of Section Headings.
%         Usually placed after \titlepage
%         If * is placed, no page numbers will appear.
%
%       \sectioncontents or sectioncontents*
%           (Placed outside \begin{slide} ... \end{slide})
%         Generates a Table of Contents that Consists of Section Headings
%         and Subsection Heading of the Following Section.
%         Usually placed before \section{...}
%         If * is placed, no page numbers will appear.
%
%    E. \section{A} or \section[A1]{A2}
%           (Placed outside \begin{slide} ... \end{slide})
%         A or A2 goes to a separate page of section heading
%         A or A1 goes to a table of contents and the right head of each page.
%
%    F. \subsection{A}
%           (Placed inside \begin{slide} ... \end{slide})
%         A frame box surrounds A.
%         A goes to a table of contents for the section.
%
%    G. \begin{slide} ... \end{slide}
%         Generates a page of slide.
%         Your slide bodies are to be placed here.
%         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
%       \begin{slide}[dimension] ... \end{slide}
%         Adds horizontal spaces by "dimension (e.g. 1in, 3em, etc.)"
%           at the left and the right of the text body (within
%           the frame).
%         Only for that page of slide.
%         cf. \defaultskip = dimension
%             for all pages of slide
%
%    H. \Underbar{...} and \Underline{...}
%         Same as \underbar and \underline except that the rule
%         is thicker.
%
%    I. Font size (Notice that all start with a capital letter)
%       \Hugesize
%       \Largesize
%       \Normalsize    - default for slides
%       \Smallsize
%
%    J. Slide head and foot
%       \lhead{...}     default: \lhead{\slidetitle}
%       \chead{...}     default: \chead{\relax}   % empty
%       \rhead{...}     default: \rhead{\sectiontitle}
%       \lfoot{...}     default: \lfoot{\slideauthor}
%       \cfoot{...}     default: \cfoot{\relax}   % empty
%       \rfoot{...}     default: \rfoot{\thepage}
%
%    K. Miscellaneous
%       \slidetitle  - prints slide title (default: \hspace*{1pt})
%       \slideauthor - prints author name (default: \hspace*{1pt})
%       \authororga  - prints organization (default: \hspace*{1pt})
%       \slidedate   - prints date  (default: \today)
%       \sectiontitle - prints section heading
%
%       \pagestyle{slide} is default for slides
%           note: \ps@slide is defined in this style file
%       \pagestyle{empty} is default for the title page,
%                              tables of contents, and section heading pages.
%
%       \Fbox{box sep}{rule thickness}{...}
%          Places a box around ...
%          box sep = spaces between ... and box rules
%          rule thickness = as you can guess
%          e.x., \Fbox{3pt}{1pt}{Box Me}

%          Places a shadow box around ...
%          box sep = spaces between ... and box rules
%          e.x., \SFbox{3pt}{1pt}{2pt}{Box Me}
%
%    L. Final Notes, Bugs, Comments, etc.
%       This is a prototype. It will be extended in the future:
%          - Various types of slide frames are desirable.
%            Users may select.
%          - \begin{note} ... \end{note} is useful.
%          - Top-bottom centering (vertical centering) can be done by \vertcenter.
%            Left-right centering (horizontal centering) may be implemented.
%          - Postscript specific features ???
%            With postscript, lots of things can be done easily (?!).
%            But, I personally discourage postscript specific features,
%            because I myself use non-postscript printers more often.
%          - Probably, new font definitions are needed, instead of
%            using those (i.e. defaults) of LaTeX/AmSLaTeX, 'cause
%            many of them are not used at all and we may need
%            big fonts with various shapes.
%
%       How to get (bold) sans serif fonts instead of roman fonts:
%          - If you use AmSLaTeX (with the new font scheme), it's simple:
%                   \begin{document}\sf
%                   \begin{document}\sf\bf
%            Or something more ... (especially to get bold math)
%          - If you use LaTeX, it's not simple.
%            ``\begin{document}\sf\Normalsize'' or
%            ``\begin{document}\sf\Normalsize\bf''
%               handles many (but not all) cases.
%            The best way is to define a style file (or using
%               one if available) which sets \sf (or \sf\bf) as default.
%            Or you may create a .fmt file after modifying
%               lfonts.sty.
%          - Personally, I modified a font file (fontdef.max) for AmSLaTeX
%            and created a lslide.fmt file so that bold sans serif
%            is default for text and bold symbol fonts are
%            default for math.
%            However, unfortunately, not all AmS bold fonts
%            are available!!!
%
%       Bugs
%           - Probably a few (or many???).
%           - I can't locate them. I need your help...
