\section*{Introduction}

This is an extremely simple document that showcases some of \DIFaddbegin \DIFadd{the }\DIFaddend latexdiff features.
Type
\begin{verbatim}
latexdiff -t UNDERLINE example-draft.tex example-rev.tex > example-diff.tex
\end{verbatim}
to create the difference file.  You can inspect this file directly. Then run either 
\begin{verbatim}
pdflatex example-diff.tex
xpdf example-diff.pdf
\end{verbatim}
or
\begin{verbatim}
latex example-diff.tex
dvips -o example-diff.ps example-diff.dvi
gv example-diff.ps
\end{verbatim}
to display the markup.

\section*{\DIFdelbegin \DIFdel{Another }\DIFdelend \DIFaddbegin \DIFadd{Yet another }\DIFaddend section title}

 \DIFdelbegin \DIFdel{A paragraph with a line only in the draft document.  }\DIFdelend More things could be said were it not for the constraints of time and space.

\DIFaddbegin \DIFadd{A paragraph with a line only in the revised document.  }\DIFaddend More things could be 
said were it not for the constraints of time and space.

And here is a \DIFdelbegin \DIFdel{tipo}\DIFdelend \DIFaddbegin \DIFadd{typo}\DIFaddend . 

Here is a table:

\begin{tabular}{ll}
Name & Description \\
\hline
Gandalf & \DIFdelbegin \DIFdel{Grey }\DIFdelend \DIFaddbegin \DIFadd{White }\DIFaddend \\
Saruman & \DIFdelbegin \DIFdel{White
}\DIFdelend \DIFaddbegin \DIFadd{Evil
}\DIFaddend \end{tabular}

And \DIFdelbegin \DIFdel{sometimes a whole paragraph gets completely rewritten. In this
case latexdiff marks up the whole paragraph even if some words in it
are identical}\DIFdelend \DIFaddbegin \DIFadd{now for something completely different, with not a paragraph in sight}\DIFaddend .
No change, 
no markup!
