+\maketitle
+
+\noindent
+The fwlw package provides a mechanism to determine the first and
+last words on the current page, plus the first word on the \emph{next}
+page.  (So perhaps it should have been named `fwlwnw'). These words
+can be used in head-lines or foot-lines.  The `words' you see may 
+not be real words, but any unbreakable object.
+
+Two pagestyles are defined to print these words: 
+\verb+\pagestyle{NextWordFoot}+ which helps you read ahead to the 
+word on the next page; and \verb+\pagestyle{fwlwhead}+ which is like 
+the headers in a lexicon.  Or you can use the
+words in your own page-style. The words are made available in the box
+registers:
+%
+\begin{labeling}[\hspace{\labelsep}--]{\quad\cmd{\FirstWordBox}}
+\setlength\itemsep{0pt}
+\item[\quad\cmd{\FirstWordBox}] first word on this page
+\item[\quad\cmd{\NextWordBox}] first word on next page
+\item[\quad\cmd{\LastWordBox}] last word on this page
+\end{labeling}
+%
+Use them in your header lines like: \verb+\usebox\LastWordBox+.
+
+Such labelling does not make sense when \cmd{\chapter} generates a page
+break, so the last page before a \cmd{\chapter} (or any \cmd{\clearpage}) gets 
+a blank ``next word'', and the first page of the chapter gets a blank
+``first word''. The fwlwhead page style produces blank headers on 
+float pages.
+
+Note that `words' are any unsplittable unit and may be things like:
+%
+\begin{itemize}
+\setlength\itemsep{0pt}
+\item two\textvisiblespace words (\texttt{two}%
+      \lower 2pt\hbox{\verb+~+}\texttt{words})
+      with unbreakable space between them
+\item \widevisiblespace Word  (where \widevisiblespace\ represents a 
+      paragraph indent)
+\item a whole displayed equation
+\item the first column of an aligned equation
+\item a list item label
+\item anomalously blank, if there are \cmd{\write}s or split footnotes etc.
+\item blank for the first word of the document (because of a \cmd{\write})
+\item partial words like  `par-'  or  `-tial' due to hyphenation.
+\end{itemize}
+%
+In short, a wide range of irregularities will cause non-words to
+be captured, or nothing at all.
