+% \section{Introduction}
+%
+% Widows (single lines at the top of a page) happen frequently
+% and should be avoided.
+%
+% The |\widowpenalty| command allows to prevent them,
+% but its syntax is a bit complex to use.
+%
+% The \textsf{nowidow} package provides a |\nowidow| command which is simpler
+% to use in order to prevent widows.
+%
+% \section{Usage}
+%
+% To load the package, use:
+%
+% \begin{verbatim}
+% \usepackage{nowidow}
+% \end{verbatim}
+%
+% \DescribeMacro{\nowidow}
+%
+% To prevent widows in a paragraph, call |\nowidow|
+% immediatly at the of the paragraph (without an empty line),
+% optionally followed by the minimal number of lines you
+% want after the page break:
+%
+% \begin{verbatim}
+% This paragraph overflows to the next page,
+% but I really don't want any widows in it.
+% \nowidow[3]
+% \end{verbatim}
+%
+% The minimal number of lines to be kept after
+% the page break defaults to 2 if not specified.
