% Class: MLOslides.cls
%
% Home-brewed style file for slides, based on the "seminar" package
% by Timoty van Zandt; have a look at the documentation available for
% the above package, e.g. under the URLs:
%
%    http://wwwcdf.pd.infn.it/localdoc/seminar.ps.gz
%    http://wwwcdf.pd.infn.it/localdoc/seminar_faq.ps.gz
%
% Instructions:
%
% 1) Put a \documentclass[options]{MLOslides} as class declaration for
%    your document; "options" is a list of, well, options to be passed
%    to "seminar": e.g., you may want to use something like:
%
%    \documentclass[a4,portrait]{MLOslides}
%
% 2) "MLOslides" includes for you the following packages: "color";
%    "graphicx"; "amsmath"; "amssymb"; "paralist".  You may want to
%    add after the \documentclass other packages you need, e.g.
%
%    \usepackage[italian]{babel}
%
% 3) "MLOslides" defines the following new commands and environments:
%
%    - \slideTitle: a command to define a title to be printed in a
%      box, to be used e.g. like:
%
%      \slideTitle{The title of this slide}
%
%      - a compact itemize-like environment, "myt", defined through the
%        package "paralist".  To be invoked e.g. like:
%
%      \begin{myt}{$\bullet$}
%      \item ...
%      \item ...
%      \end{myt}
%
%    - a new page style, "slidata", valid both for landscape- and
%      portrait-oriented slides; to be used e.g. with
%
%      \pagestyle{slidata}
%
%      "slidata" uses three internal commands: \presTitle, \presAuthor
%      and \presStyle.  The first two (the "presentation title" and
%      the "author name") *MUST* be defined by the user with
%      \newcommand; the third one is already defined as a do-nothing
%      command, and *MAY* be REdefined with \renewcommand e.g. in
%      order to change the fonts used for presentation title, author
%      name and slide number (that command is used right before these
%      printouts).  Example:
%
%      \newcommand{\presTitle}{How I discovered the Higgs boson}
%      \newcommand{\presAuthor}{Maurizio Loreti}
%      \renewcommand{\presStyle}{\bold}
