+\section{Documentation}
+
+This packages two commands, \cs{needspace} and \cs{Needspace}, for reserving
+space to keep a certain amount of material from being split over a page break.
+If there is not enough space, a `\newpage' is automatically inserted.
+
+The \cs{needspace}\meta{length} macro reserves an \emph{approximate} amount of space \meta{length} for
+the material following to be kept on the same page. The accuracy of its
+calculations depend on what penalties are in effect, but is efficient and
+normally adequate. A short page will be ragged bottom even if \cs{flushbottom}
+is in effect.
+
+\cs{Needspace}\marg{length} is less efficient but reserves the requested space \meta{length} exactly. It
+should only be used between paragraphs. Short pages that are produced by
+\cs{Needspace} will be ragged bottom but short pages produced by
+\cs{Needspace*}\marg{length} will be flush bottom if \cs{flushbottom} is in
+effect.
+
+\section{Examples}
+
+Here, we request that we need next five lines on a single page/column:
+\begin{verbatim}
+... previous text.
+
+\needspace{5\baselineskip}
+The next five lines ...
+\end{verbatim}
+In this case, the space is reserved more accurately:
+\begin{verbatim}
+... previous text.
+
+\Needspace*{4\baselineskip}
+ The major principles are:
+\begin{itemize}
+\item ...
+\end{verbatim}
