\section{ABSTRACT}
There are some things to note in the \LaTeXe{} version of
the CHI~96 publishing guidelines. Certain things have to be
done by the author because its rather difficult to implement
them in \LaTeXe.

\section{OTHER PACKAGES}
Be very carefull when using the CHI 96 class with other packages.
Esp. when these packages change the page dimensions. For example,
if you use the a4 package with chi96, you will get wrong page dimension.

Another point: don't use tools like \textsf{babel} or the like. This is
no real problem, since the required language for proceedings is english.

\section{TITLE}
There is a little thing to note about the title. We want to use
the |multicolumn| package to balance the columns on the last page.
And we want to do it transparent, so the user must \textit{not}
begin multicolumn mode or end it. To do this, |chi96.cls| switches
multicolumn mode on when it sees the |\begin{document}| clause.
And because we want the title to span across the whole page we
issue |\maketitle| at that moment, too. So, the author has to specify
its |\title| and |\author| commands in the preamble of the work,
\textit{before} the |\begin{document}|. Although |chi96| calls |\maketitle|
automatic we advise the use of an `additional' |\maketitle| command
after the |\begin{document}| clause, since when \textit{not} using
|multicolumn| but |twocolumn| we'll need it. It will not hurt, since
after the first |\maketitle| call the macro is redefined to be |\relax|.

Another small problem: The authors name shall be printed in \textbf{boldface}.
There are two possible solutions: split the |\author| macro by specifying
an additional macro |\address|. Or take care of it yourself. We provide
the second solution:-)

\section{SECTIONS}
CHI wants section titles to be all uppercase, subsections
should have only the first letter capitalized. Please, take
care of that for yourself.

\section{COPYRIGHT}
The copyright box should be 2.5cm on the bottom of the first page,
first column. This could be done by changing certain things in
|multicols|-package which is, to be frankly, very difficult
and may break other features. Please take care of the copyright box
by using explicit space in the following form:

\begin{verbatim}
\vspace*{2.5cm}
\end{verbatim}

Maybe you have to move this a little bit around until it fits. Sorry
for the inconvinience.

The same applies to the second copyright, as shown in |camera2.tex|.
You have to enter the line
\textbf{\emph{\copyright{}~Copyright~on~this~material~is~held~by~the~author(s)!}}
by hand.

\section{GENERAL}
You will probably notice differences when comparing a work written with
\textsf{WORD} under Microsoft Windows or MacOS. There's nothing we or you can
do about that. \TeX's linebreaking algorithm is different from the one used
by common Wordprocessors. 
We don't say its better because we don't
want to start a religious war right here. Its just different. Most of the
time this will result in a longer document, compared to a similar Wordprocessor
output. (In fact, this may be rather small. For example, the \LaTeXe{} version
of |camera1| is about 4 lines longer than its \textsf{WORD} counterpart. And
this is caused by a format violation by the \textsf{WORD} version\dots)

\section{FONTS}
The default CHI~96 font ist \textit{Times Roman}, which is only availiable
with the option |psfonts| for \LaTeXe{} users. This requires the 
|times| style, which is part of the \textsf{psnfss} package, to be installed.

\section{COLUMNS}
We provide two methods for the required two column layout. The first is
the builtin |twocolumn| option, the second needs the package |multicols|
from \LaTeXe's |tool| collection. We think the second is better because it
balances the columns on the last page. 

\section{Other \LaTeXe{} features}
We have tried many different \LaTeXe{} files with this class but we are
\emph{not} sure we covered every possible problem. So expect problems,
esp. if you are working with tables and figures. (Note the restricitons for
floating objects together with the |multicols| package.) Contact us
if you experience problems, we will try to provide at least a work around.

It does work with \LaTeXe{} in compatibility mode, i.e. a current \LaTeXe{}
emulating old \LaTeX{} 2.09. We can not guarantee for older versions,
either \LaTeX{} or \LaTeXe{}. But, if it fails for your version, please
send us a short bug report, outlining the problems or errors you get.

\section{Conclusion}
That's about it. One last thing: if you find a bug or a problem, send a quick
email describing the problem to |ts@uni-paderborn.de|, probably together
with a short file which triggers the bug.
