\maketitle
\noindent
Provides commands to reserve space at the bottom of a page. If there
is not enough space on the current page (column) a new page (column)
is started.

\section{Example uses:}
\begin{verbatim}
... previous text.\par
\needspace{5\baselineskip} % need next 5 lines on a single page/column
The next five lines ...
\Needspace*{4\baselineskip} % need 4 lines kept on same page
The major principles are:
\begin{itemize}
\item ...
\end{verbatim}
The \cmd{\needspace} macro reserves an \emph{approximate} amount of space (depending
on what penalties are in effect) but is efficient and normally adequate.
A short page will be ragged bottom even if \cmd{\flushbottom} is in
effect.
\cmd{\Needspace} is less efficient but reserves the requested space. It
should only be used between paragraphs. Short pages produced by
\cmd{\Needspace}\marg{length} will be ragged bottom but short pages produced by
\cmd{\Needspace*}\marg{length} will be flush bottom if \cmd{\flushbottom} is in effect.
\section{Changes:}
\begin{description}
\item[Changes v1.3b (2009/09/03)]
New maintainer (Will Robertson)
\item[Changes v1.3a (2003/02/18)]
At the suggestion of Donald Arseneau (private emails) changed guts of
\cmd{\needspace} from
\ldots\verb+\vskip\z@\@plus\dimen@\pagebreak[3]+\allowbreak
\verb+\vskip\z@\@plus-\dimen@\endgroup}+
\item[Changes v1.3 (2003/02/07)]
Added \cmd{\Needspace} (an extended version of postings by Donald Arseneau
to \texttt{comp.text.tex} e.\,g.,\ in November 1993, August 1995, September 1997, \ldots)
\item[Changes v1.2 (2002/09/11)]
At the suggestion of Robin Fairbairns, added use of \cmd{\dimen@} to capture
the argument so that \pkg{calc} package commands can be used in the argument.
