+\maketitle
+\advance\baselineskip by 1pt
+
+\noindent We often encounter nightmarish scenario while generating
+final versions of a long document when one or more of the following
+happens:
+\begin{enumerate} 
+\item New revised versions of packages used. 
+\item Smaller changes to a fewer number of pages of a long document.
+\item No change in the document, but recompiled with revised page
+  numbers as it happens during compilation of journal articles into an
+  issue for printing. 
+\item Simply you happened to retypeset for no reason and then you're
+  forced to check each page for surprises.
+\end{enumerate}
+
+Now you are left with the job of comparing the \textsc{pdf}s generated
+now and that of previous version and it is not fun. To make the job
+easier, |pdgpagediff| package is written.
+
+\section{Principles}
+
+We have a version of document, say, |file1.pdf| and we have its
+revised version, |file2.pdf|.  |pdfpagediff| will create a composite
+pdf by juxtaposing each page of |file1.pdf| over the corresponding
+page of |file2.pdf| or vice-versa. Since the pdf's are transparent,
+you can notice the slightest change visually by simply flipping
+through the pages.
+
+\section{Dependencies}
+
+|pdfpagediff| depends on the following packages:
+\begin{enumerate}
+\item |geometry.sty|
+\item |graphicx.sty|
+\item |color.sty|
+\item |substr.sty|
+\end{enumerate}
+
+\section{Usage}
+
+Package can be loaded with the following command:
+\begin{verbatim}
+  \usepackage{pdfpagediff}
+\end{verbatim}
+Another command |\layerPages| has been defined to include two versions
+of the \pdf documents to create the composite document, the syntax is:
+\begin{verbatim}
+  \layerPages[<optional page numbers>]{<file1>}{<file2>}|
+\end{verbatim}
+First one doesn't have an optional argument of page numbers, which
+means all the pages will be used to create the composite document.
+Second one has comma separted page numbers and hyphen separated page
+ranges which can be mixed in any order as shown in subsequent examples
+of usage. The last one has |10-| which means from page |10| to end
+of the document.
+
+\begin{enumerate}
+\item |\layerPages{file1.pdf}{file2}|
+\item |\layerPages[1,2,4-6,8]{file1}{file2.pdf}|
+\item |\layerPages[1,2,4-6,8,10-22]{file1.pdf}{file2.pdf}|
+\item |\layerPages[1,2,4-6,8-13,17]{file1}{file2.pdf}|
+\item |\layerPages[10-]{file1.pdf}{file2.pdf}|
+\end{enumerate}
+You need Adobe Reader to view the composite document which only
+provides to view each layer or all layers together or no layers at
+all.  There is a small layer button at top left hand side of the
+Adobe Reader window, see the figure below:
+
+\medskip
+\noindent\includegraphics[width=\linewidth]{ar1}
+
+\medskip\noindent
+You can see |Layers| icon, clicking on the icon will show you the
+layers.  We have two layers in this example, namely, |First| and
+|Second| which are also the default.  These labels can be changed with
+|\FirstDoc| and |\SecondDoc| commands respectively. 
+
+\subsubsection*{First Document}
+\noindent\includegraphics[width=\linewidth]{ar2.png}
+
+\medskip\noindent The above figure shows the first document alone. You
+might note that icon for second layer is not visible now.
+
+\subsubsection*{Second Document}
+\noindent\includegraphics[width=\linewidth]{ar3.png}
+
+\medskip\noindent The second document is generated with 30\% gray
+instead of black to facilitate easy indication of locations with
+differences. Also, note that icon for first layer is invisible since
+the second layer alone is mode visible here.
+
+\section{Examples}
+
+You might take a look at Clip \ref{clip1} which has a paragraph from
+the composite document. The last word of the paragraph has a
+mismatch. 
+
+\src{A paragraph from composite document.}
+\includeclip{3}{104 419 508 556}{ltest.pdf}
+
+Now let us take a look at the last two lines of the above para from
+the first document:
+
+\src{Last two lines from first document.}
+\includeclip{3}{104 380 508 408}{file1.pdf}
+
+Here is the same location of the second document:
+
+\src{Last two lines from second document.}
+\includeclip{3}{104 380 508 408}{file2.pdf}
+
+\noindent The difference is a space added before the last word
+`concepts'. If you look at Clip \ref{clip1} now, you will get to know
+the difference quickly.
+
+Further differences can be observed in pages 9 and 17 of the included
+document, |ltest.pdf|.
+
+\section{Limitations}
+Following limitations apply:
+\begin{enumerate}
+\item Documents with enormous changes cannot be comapared.
+\item Documents with opaque backgrounds cannot be compared.
+\item Tables and figures with background will not provide any
+  meaningful information even if there are differences.
+\item This is not a character by character or word by word diff
+  program, instead it depends largely on your eyes very much.
+\item |pdfpagediff| will work only with \pdftex and will not work with
+  any other \tex compilers.
+
+\end{enumerate}
+
