\section{Introduction}

This note exemplifies the sytle zpaper.sty, which is intended for writing papers and works on top of \LaTeX's article document class. Feel free to use this style file. If you have trouble finding it, or if you are looking for an up-to-date version, or if you have any question, feel free to write me at luis.cabral@nyu.edu

The style zpaper.sty is primarily about re-formatting the article document class. 
\begin{itemize}\itemsep0pt
\item Title command (sansserif font, left adjusted)
\item Section, theorem, table and figure commands (sansserif font, dot after number; in case of table and figure, number and caption are left adjusted)
\item Footnotes. See example below (firstfootnote command) as well as on the next page.
\item Proof environment (see example on next page).
\item Margins (0.25truein, which I think looks better)
\end{itemize}
Before continuing, the always-needed disclaimer: I do not claim that everything in the style file zpaper.sty works perfectly and will not be responsible for all the time you may waste working with this. That said, I should add that the file zpaper.sty is so small that it can actually be included in your paper's preamble. Alternatively, do as I do in this file: import the file zpaper.sty. (Note: if you work off of this file, you must change the file path to zpaper.sty accordingly.)

\section{Examples}

Below I present a few examples of how this actually comes out: a table, then a proposition, a proof, a footnote.

\begin{table}
\caption{Example of a table caption}
\label{tab:example}
\begin{tabular}{|c|c|} \hline
a & 1 \\ \hline
b & 2 \\ \hline
c & 3 \\ \hline
d & 4 \\ \hline
e & 5 \\ \hline
\end{tabular}
\end{table}

\begin{proposition}
\label{prop:example}
This is an example of how a theorem is formatted.
\end{proposition}

\begin{proof}
This would be the proof of the proposition. Since I'm including it right after the text of the proposition, I use the proof environment without any of its optional arguments. Contrast with the Appendix below.
\end{proof}

\section{Conclusion}

That's essentially it for zpaper.sty.\footnote{The zpaper style changes the general footnote format. First, the footnote number appears to the left of the footnote text. Second, the text is placed in raggedright format.}
 If you have any suggestions for improvement, please let me know. Also, I have quite a number of additional style files like this one: zmain.sty, zstile.sty, zsyllabus.sty, zplot.sty, zcase.sty. I will be happy to share these with you.

\section*{Appendix}

\begin{proof}[Proposition][prop:example]
If you are placing the proof of a proposition in an appendix, you want to refer its number. Use the optional arguments of the proof environment for this purpose.
\end{proof}
