%%% so but don't call i AAT.CLS. See the licence for details.)

%%% IMPORTANT! This class requires the memoir class, which can be
%%% downloaded from CTAN. It won't work without it! The memoir class
%%% is a very powerfull document class which gives wast possibilites
%%% to the design of the page. It also requires the Times package (the
%%% Times font), the ifthen package and the multicol package.

%%% As already stated, AAT.CLS is a LaTeX class to produce the back
%%% page of the Al Amarja Today newspaper, the page with
%%% ''Oppertunities On The Edge'' and ''Little Scratches''. It is not
%%% restricted to the oppertunities and little scratches, also
%%% ''ordinary'' news articles can be incorporated. Except for
%%% the class options (see below) it also contains a small number of
%%% commands and environments to ease the task.

%%% It currently only supports A4 paper in portrait, or to be
%%% specific: It *requires* A4 paper in portrait.

%%% Class options and usage of the class:

%%% \documentclass[options]{aat} where options are either
%%% ''playerversion'' (default, used if no option is given) or
%%% ''GMversion''. They are mutually exclusive and the difference is
%%% that in ''GMversion'', the GM note is printed (see the environment
%%% aatnote*)

%%% Commands:

%%% There are five commands that the user need to bother about:

%%% \aatheading  Used in an aatnote or aatnote* environment and
%%%              produces the bold heading in the notes. Takes two
%%%              arguments, one optional and the heading. The optional
%%%              is the name of the command (without the backslash) to
%%%              format the heading. Valid optional arguments are
%%%              ''textbf'' (default) and friends:
%%%              \aatheading{Money for Fighting}
%%%              \aatheading[textit]{Money for Fighting}

%%% \littlescratches  Produces the texts ''Oportunites on Al Amarja''
%%% \opportunites     and ''Little Scatches''.

%%% \newsheadline     Produces a news headline, like ''Peace Force's
%%%                   campain on drug abuse continues.'' It takes one
%%%                   argument that is the headline.

%%% \sectionfontname  The name of the section font according to
%%%                   NFSS. Default is ''egs'', use
%%%                   \renewcommand{\sectionfontname}{ptm} to use
%%%                   Times for section headings too. (egs is Gill Sans.)

%%% \AATheadline  Produces the headline for the page (''The only
%%%               news...'' etc.), use it after \begin{document}.
%%%               Takes two arguments, the issue number and the author
%%%               (or any other misc. text). The second argument, the
%%%               author, is not produced unless it's a GM's
%%%               version.

%%% Environments:

%%% There are one environment, aatnote, and a starred version of it.
%%% The unstarred version is straight forward. It produces its
%%% contents with some space to the note before and after. The starred
%%% version takes one argument which is a GM's note. If the
%%% ''GMversion'' class option is used, this note is printed after the
%%% aatnote. I.e. to produce a GM's version of the page which he uses
%%% for his own reference. With the ''playerversion'', this GM's note
%%% is naturally not printed.

%%% \begin{aatnote}
%%%   Blah blah.
%%% \end{aatnote}

%%% \begin{aatnote*}{More blah blah.}
%%%   Blah blah.
%%% \end{aatnote*}

%%% Usage:

%%% Use \documentclass[options]{aat} with the option of you choice,
%%% load other packages etc. Then begin the document,
%%% \begin{document}, call \AATheadline with the arguments of your
%%% choice. The next thing to do is to is to begin a four multicolumn
%%% environment, \begin{multicols}{4}, and to use \opportunites. After
%%% all opportunites, call \littlescratches and then end the multicols
%%% environment and the document itself.
