+
+## Warning
+
+This package is now in *legacy status*. Functionality similar to that provided
+by this package is directly implemented in LaTeX since its 2020 Fall
+release. Do not use everypage in new documents and do not rely on it in new
+packages or classes of yours.
+
+When running on a pre-2020-10-01 version of LaTeX, `everypage` will now fall
+back to `everypage-1x`, its own past code base.
+
+When running on a modern LaTeX, `everypage` will strive to provide its legacy
+interfaces by using the newer LaTeX facilities. However, full equivalence is
+not possible and breakage may occur. Load `everypage-1x` in place of
+`everypage` if you really want to force usage of the old code base (that might
+keep working for a few more LaTeX release cycles).

 % \section{Introduction}
-% 
-% This program adds two \LaTeX\ hooks that get run when document
-% pages are finalized and output to the dvi or pdf
+%
+% Until a recent past, \LaTeX\ provided no explicit hooks to be run as
+% documents pages were finalized and output to the dvi or pdf
+% file. Consequently, many solutions were developed to work around this
+% limitation and to offer features (e.g., watermarks) that would otherwise
+% be impossible. These solution included packages such as
+% \Lpack{everyshi}, \Lpack{bobhook} and \Lpack{watermark}. Package
+% \Lpack{everypage} was a solution providing plumbing that could be used
+% in higher level packages such as \Lpack{draftwatermark} (watermarking)
+% and \Lpack{flippdf} (print preprocessing) to mention a couple of them.
+%
+% All of these extensions relied on applying modifications to some \LaTeX\
+% internals and as such were prone to subtle interactions with other
+% packages and breakage. The situation has been cleared by the 2020 Fall
+% \LaTeX\ release where an official and generic support for hooks has been
+% introduced.
+%
+% As of today, \Lpack{everypage} can be considered obsolete. It needs to
+% remain around because older releases of \LaTeX\ are still in use and
+% legacy code exist that is based on the interfaces it exposes. However,
+% no new document, class or package should be based on it. Furthermore, it
+% can be expected that existing packages that use \Lpack{everypage} will
+% progressively learn to rely directly on the new \LaTeX\ hook mechanism.
+%
+% This manual is meant to aid the transition by showing how
+% \Lpack{everypage} is now being updated to cater both for older and newer
+% \LaTeX\ kernels. Specifically, it illustrates:
+% \begin{enumerate}
+% \item how \Lpack{everypage} is now actually split in two packages:
+%   \Lpack{everypage-1x}, providing the old code base; and
+%   \Lpack{everypage} itself, that strives to implement the legacy
+%   interface on top of the new mechanisms offered by \LaTeX;
+% \item how \Lpack{everypage} can automatically import the old code base
+%   as needed, how loading of the latter can be forced (if absolutely
+%   needed or for comparison) and for how long the old code can be
+%   expected to keep working with newer releases of \LaTeX;
+% \item how the legacy interface of \Lpack{everypage}, once
+%   implemented/emulated on top of the new \LaTeX\ facilities actually
+%   differs from its nominal behavior.
+% \end{enumerate}
+%   
+% \section{The original code base}
+% \label{sec:original}
+% \changes{R1.0}{2006/06/30}{%
+%   Initial release.}
+%
+% The original implementation of \Lpack{everypage}, now available as
+% \Lpack{everypage-1x}, adds two \LaTeX\ hooks that get
+% run when document pages are finalized and output to the dvi or pdf
 % file. Specifically, one hook gets executed on every page, while the
 % other is executed for the current page. Hook actions are are performed
-% \emph{before} the page is output on the medium, and this is
-% important to be able to play with the page layout or to put things
-% \emph{behind} the page contents (e.g., watermarks such as an image,
-% framing, the ``DRAFT'' word, and the like).
-% 
-% The package reminds in some sense \Lpack{bobhook} by Karsten
-% Tinnefeld, but it differs in the way in which the hooks are
-% implemented:
+% \emph{before} the page is output on the medium, and this is important to
+% be able to play with the page layout or to put things \emph{behind} the
+% page contents (e.g., watermarks).
+%
+% \subsection{User interface}
+% \label{ssec:ui}
 % 
+% \DescribeMacro{\AddEverypageHook} The |\AddEverypageHook| command
+% accepts one argument and adds it to the list of hooks that are run
+% before every page is output. Similarly, the
+% \DescribeMacro{\AddThispageHook}|\AddThispageHook| command accepts one
+% argument, however it adds it to the list of hooks that are run before
+% the \emph{current} page is output.
+%
+% The following rules apply:
+%
 % \begin{enumerate}
-% \item there is no formatting inherent in the hooks. If one wants to
-%   put some watermark on a page, it is his own duty to put in the
-%   hook the code to place the watermark in the right position. Also
-%   note that the hooks code should \emph{eat up no space} in the
-%   page.  Again, if the hooks are meant to place some material on the
-%   page, it is the duty of the hook programmer to put code in the
-%   hooks to pretend that the material has zero width and zero height.
-%   The implementation is \emph{lighter} than the \Lpack{bobhook} one,
-%   and possibly more flexible, since one is not limited by any
-%   pre-coded formatting for the hooks. On the other hand it is
-%   possibly more difficult to use. Nonetheless, it is easy to think
-%   of other packages relying on \Lpack{everypage} to deliver more
-%   user-friendly and \emph{task specific} interfaces. Already there
-%   are a couple of them: the package \Lpack{flippdf} produces
-%   mirrored pages in a PDF document and \Lpack{draftwatermark}
-%   watermarks document pages.
-% \item similarly to \Lpack{bobhook} and \Lpack{watermark}, the
-%   package relies on the manipolatoin of the internal \LaTeX\ macro
-%   |\@begindvi| to do the job. However, the redefinition of
-%   |\@begindvi| is here postponed as much as possible, striving to
-%   avoid interference with other packages using |\AtBeginDvi| or
-%   anyway manipulating |\@begindvi|. Specifically \Lpack{everypage}
-%   makes no special assumption on the initial code that |\@begindvi|
-%   might contain.
+% \item once hooks are introduced and stacked in a series, there is no way
+%   to unstack them, nor to clear them;
+% \item in order to have hooks that get run only when specific conditions
+%   are met, conditionals must be included in the hooks;
+% \item \label{itm:formatting}%
+%   there is no formatting inherent in the hooks. If one wants to put some
+%   watermark on a page, it is his own duty to put in the hook the code to
+%   place the watermark in the right position and with the appropriate
+%   appearance and style. When the hooks are run, the page is still empty,
+%   so that one begins filling it at point (1\,inch, 1\,inch) from the top
+%   left corner;
+% \item \label{itm:nospace}%
+%   the hook code should \emph{eat up no space}. This means that hooks
+%   meant to place some material on the page, need to have the material
+%   placed in a box with zero width and height beforehand.
+% \item no particular assumption is made on the \LaTeX\ output
+% driver, so \Lpack{everypage} should work equally well with \LaTeX,
+% \hologo{pdfLaTeX}, \hologo{LuaLaTeX}, or \hologo{XeLaTeX}. Similarly,
+% the package should work equally well with dvi, dvips, etc.\@ output
+% drivers. Obviously, the final compatibility with the different output
+% drivers depends on the actual code that is placed in the hooks.
 % \end{enumerate}
 %
-% Also in some sense \Lpack{everypage} can be related to package
-% \Lpack{everyshi} by Martin Schroeder, but it differs radically from
-% it in the implementation. In fact,\Lpack{everypage} operates by
-% manipulation of the |\@begindvi| macro, rather than at the
-% lower level |\shipout| macro.
-% 
-% \section{User interface}
-% \DescribeMacro{\AddEverypageHook}\DescribeMacro{\AddThispageHook}
-% The |\AddEverypageHook| accepts one argument and adds it to the list
-% of hooks that are run before every page is output. The
-% |\AddThispageHook| accepts one argument and adds it to the list of
-% hooks that are run before the current page is output.
-%
-% Note that once hooks are stacked, there is no way to unstack them,
-% nor to clear them. In order to have hooks that get run only when
-% specific conditions are met, conditionals must be included in the
-% hooks.
-% 
-% Also note that no particular assumption is made on the \LaTeX\
-% output driver, so \Lpack{everypage} should work equally well with
-% \LaTeX\ and pdf\LaTeX. Furthermore, the package should work equally
-% well with dvi, dvips, etc.\@ output drivers. Obviously, the final
-% compatibility with the different output drivers depends on the
-% actual code that is placed in the hooks.
-%
-% For usage examples, please see the \Lpack{flippdf} and
-% \Lpack{draftwatermark} packages.
+% \subsection{Comparison with other packages}
 % 
+% The purpose of the original code base is better understood by comparing
+% it to other packages that were meant to solve related problems at the
+% time when \LaTeX\ had no hook mechanism of its own:
+%
+% \begin{itemize}
+% \item In comparison with \Lpack{bobhook} by Karsten Tinnefeld,
+%   Lpack{everypage} (in its legacy incarnation) used to differ in purpose
+%   and in the hook implementation. Package \Lpack{everypage} was meant to
+%   make no assumption on what one could want to do on every page, whether
+%   to add text, images, or some low-level instruction for the output
+%   driver, or even to perform some accounting task. This made the package
+%   lighter and more flexible at the cost of being more difficult to
+%   use. In other words, \Lpack{everypage} was meant to be more of a
+%   plumbing to be employed in higher level packages;
+% \item in comparison with \Lpack{watermark} by Alexander I.~Rozhenko,
+%   similar considerations could me made. Specifically, \Lpack{watermark}
+%   is explicitly targeted at making it easy to put watermarks on document
+%   pages, while \Lpack{everypage} is lower level.
+% \item in comparison to both \Lpack{bobhook} and \Lpack{watermark},
+%   \Lpack{everypage} used to employ a similar low level mechanism, by
+%   manipulation of the internal \LaTeX\ macro |\@begindvi| to do the
+%   job. However, the redefinition of |\@begindvi| in \Lpack{everypage}
+%   was postponed as much as possible, striving to avoid interference with
+%   other packages using |\AtBeginDvi| or anyway manipulating
+%   |\@begindvi|. Furthermore, \Lpack{everypage} made no special
+%   assumption on the initial code that |\@begindvi| might contain.
+% \item in comparison with \Lpack{everyshi} by Martin Schroeder,
+%   \Lpack{everypage} used to be similarly low level, but relied on
+%   changing the |\@begindvi| macro, rather than the even lower-level
+%   |\shipout| macro.
+% \end{itemize}
+%
+% \subsection{Known applications of the \Lpack{everypage} code}
+%
+% Package \Lpack{everypage} has historically found application in at least
+% two higher level packages, namely:
+% \begin{itemize}
+% \item \Lpack{draftwatermark}, meant at providing extended facilities for
+%   page watermarking on all \LaTeX\ engines and output drivers; and
+% \item \Lpack{flippdf}, meant at catering for a frequent preprint
+%   requirement, where publisher may require a document with
+%   \emph{mirrored} pages to get the best results out of a photographic
+%   printout process.
+% \end{itemize}
+%
+% \section{The new code base}
+% \changes{R2.0}{2020/10/11}{%
+%   Complete package rewrite to take advantage of the new
+%   LaTeX hook mechanisms introduced in the Fall 2020 release.}
+%   
+% The new code base differs from the old one because it does not touch
+% any \LaTeX\ internals. Conversely it relies on the hook mechanism that
+% is officially provided by \LaTeX\ since its 2020 fall release.
+% Obviously, this has no other purpose than to provide back
+% compatibility for older \LaTeX\ code written before such \LaTeX\
+% release and relying on the original \Lpack{everypage} interfaces.
+%
+% To this aim, the new code base does the following:
+% \begin{enumerate}
+% \item complains out loud, reminding that new code should not be based on
+%   \Lpack{everypage}, but rather make direct usage of the new \LaTeX\
+%   interfaces;
+% \item checks whether the new \LaTeX\ interfaces are actually
+%   available. If this is not the case, it resorts to loading
+%   \Lpack{everypage-1x} that provides the old code base;
+% \item \label{itm:addtohook}%
+%   implements/emulates the |\AddEverypageHook| and |\AddThispageHook|
+%   commands on top of the new |\AddToHook| and |\AddToHookNext| \LaTeX\
+%   commands.
+% \end{enumerate}
+%
+% With specific reference to point \ref{itm:addtohook} above, note that
+% the new hook mechanism provided by \LaTeX\ is extensively documented in
+% issue 32 of \emph{\LaTeX\ News} and in file
+% |lthooks-doc.pdf|. Furthermore, consider that \Lpack{everypage} employs
+% hooks in the \emph{shipout} class, which are documented in file
+% |ltshipout-doc.pdf|.
+%
+% \subsection{Compatibility of the new code with the original \Lpack{everypage}
+%   interface}
+%
+% Because the implementation is different and due to choices (in fact,
+% quite reasonable ones) by the \LaTeX\ developers, the new implementation
+% of \Lpack{everypage} cannot be exactly equivalent to the original one
+% (hence, please, do not open bugs for this!).
+%
+% The main difference is the hook code provided by the user now gets
+% wrapped in a |\put| command, inside a |picture| environment with
+% |\unitlength| at 1\,pt. This is because \Lpack{everypage} relies on a
+% |shipout/background| type hook. The |\put| command typesets material at
+% (1\,in, -1\,in) to emulate the original coordinate system of
+% \Lpack{everypage}. This means that some of the points about the
+% interface in section~\ref{ssec:ui} do not apply anymore (or at least do
+% not apply in the same way). Specifically, point \ref{itm:formatting}
+% about lack of any pre-canned formatting is not completely true anymore,
+% because of the implicit picture environment. Furthermore, point
+% \ref{itm:nospace} about the need not to eat up space can now be
+% completely ignored.
+%
+% While the changes described above seem to go in the direction of less
+% rules and less concern, this might not be always true and subtle
+% breakage of legacy code may happen in corner cases.
+%
+% \section{Forcing usage of the older code base}
+%
+% The usage of the older code base of \Lpack{everypage} can be forced by
+% simply substituting |\usepackage{everypage-1x}| for
+% |\usepackage{everypage}|. In this case, no warning about the package
+% obsolescence is emitted, because it is assumed that the user knows what
+% he/she is doing. However, explicitly requiring \Lpack{everypage-1x}
+% is obviously discouraged.
+%
+% The old code base actually works just fine with the Fall 2020 \LaTeX\
+% release and it will probably keep to do so for a few more \LaTeX\
+% release cycles. This is mostly up to the \LaTeX\ developers and their
+% will to maintain untouched some internal deprecated interfaces. In any case,
+% |\usepackage{everypage-1x}| will eventually stop working and is now
+% declared in an \emph{unmaintained state}.
