+
+2004-09-13 Uwe L"uck  [(UL)]  is new maintainer for lineno.sty. 
+
+lineno.sty served the purpose for which I wrote it years ago.  Uwe
+L"uck uses lineno.sty with his Ednotes package, which required quite a
+few changes and fixes.  His package depends on lineno, therefore
+Uwe agreed to take over the maintenance of lineno.sty.
+
+lineno.sty v4.0 includes most of the well tested changes that Uwe
+needs for Ednotes.  These changes blend well into the concepts of the
+package, so I am happy to let it go.  
+
+From here on it is Uwe's, and he may proceed to mangle it as he likes.
+Expect some radical changes.  You may find him to be quite a bit
+friendlier towards the poor souls who still use Windows :-).
+Currently, you need some kind of Unix environment to extract the
+source documentation from the sty file.
+
+If some version 3 users run into difficulties with Uwe's newer
+versions, but need a minor bug-fix in version 3, please do not
+hesitate to ask me for help.  But all requests for new features or
+major changes shall go to Uwe.
+
+Cheers
+Stephan

+  compatibility problems arise!  The announced radical 
+  changes are postponed again this time (v4.1).

+
+Compatibility with other packages:
+
+   wrapfig.sty   works since v2.05
+
+   multicol.sty  works partly since 3.02.  
+                 Do NOT use \linelabel.  Do NOT put a multicol in
+                 internal vertical mode {table}, {figure}, etc.
+
+   hyperref.sty  \ref to a \linelabel works since v3.03.
+
+   longtable.sty broke with lineno.sty loaded, but not enabled. 
+                 This is fixed in v3.04.
+
+   amsmath.sty   loadable, but not fully supported, with v4.41
+
+Installation and usage (UL, v4.1): 
+
+   For being able to use ALL the new lineno.sty options, the 
+   following files must be "visible" to (La)TeX ("visible" 
+   explained below for beginners): 
+
+     lineno.sty, edtable.sty, ednmath0.sty, ltabptch.sty 
+ 
+   as above ("Home", note that clicking on "entire directory" 
+   suffices); 
+
+     longtable.sty -- from the standard LaTeX Tools bundle. 
+
+   Usage always starts with loading lineno.sty by \usepackage. 
+   The remaining .sty files are loaded automatically on the 
+   lineno.sty options (and we recommend not to load them through 
+   [the mandatory argument of] \usepackage). 
+ 
+   For details, see lineno.tex/pdf and the .sty files mentioned 
+   above--search especially for tabular and math mode. 
+   (+ `print' below here). 
+ 
+   "Visible to (LaTeX)": Some users don't understand this 
+   "visibility" for a while, and indeed it may be somewhat 
+   non-trivial. These users may find help in 
+
+      http://mirror.ctan.org/macros/latex/ednotes/visible.txt .
+
+   E.g., former users of lineno.sty may just put all the .sty 
+   files into the folder (at their workplace) where they had 
+   placed lineno.sty before.                     (/UL, /v4.1)
+
+To print the documented source:
+
+   Take the style-file `lineno.sty', and feed it to a Un*x shell. 
+   (Or download the extracted source documentation `lineno.tex'.)
+
+      csh> source ./lineno.sty
+      sh>  . ./lineno.sty
+
+   [ I.e., type `sh lineno.sty' (e.g.) as a UNIX command line. 
+     Problems with awk may arise. I therefore switched to nawk 
+     in lineno.sty v4.00, but this may trouble you as well.    (UL) ] 
+
+   (Please ignore the error message at the beginning about the iffalse.)

-This package provides line numbers on paragraphs.
-After \TeX\ has broken a paragraph into lines there will
-be line numbers attached to them, with the possibility to
-make references  through the \LaTeX\ ~\ref~, ~\pageref~
-cross reference mechanism.  This includes four issues:
-\begin{itemize}
-\item   attach a line number on each line,
-\item   create references to a line number,
-\item   control line numbering mode,
-\item   count the lines and print the numbers.
-\end{itemize}
-The first two points are implemented through patches to
-the output routine.  The third by redefining ~\par~, ~\@par~
-and ~\@@par~.  The counting is easy, as long as you want
-the line numbers run through the text.  If they shall
-start over at the top of each page, the aux-file as well
-as \TeX s memory have to carry a load for each counted line.
-
-I wrote this package for my wife Petra, who needs it for
-transcriptions of interviews.  This allows her to
-precisely refer to passages in the text.  It works well
-together with ~\marginpar~s, but not too well with displaymath.
-~\footnote~s are a problem, especially when they
-are split, but we may get there. 
-(New v4.00 UL) Version v4.00 overcomes the problem, I believe.

-Introduction to versions v4.00ff. (UL) 
-\unskip}
-
-~lineno.sty~ has been maintained by Stephan until version_v3.14.
-From version_v4.00 onwards, maintenance is shifting towards 
-Uwe L\"uck (UL), who is the author of v4\dots code and of v4\dots 
-changes in documentation. This came about as follows. 
-
-Since late 2002, Christian Tapp and Uwe L\"uck have employed 
-~lineno.sty~ for their ~ednotes.sty~, a package supporting 
-critical editions---cf.
-\[\mbox{\tt 
-http://ednotes.sty.de.vu 
-\unskip}\]
----while you find ~ednotes.sty~ and surrounding files in 
-CTAN folder \path{macros/latex/contrib/ednotes}.
-
-Soon, some weaknesses of ~lineno.sty~ showed up, mainly since 
-Christian's critical editions (using ~ednotes.sty~) needed lots 
-of ~\linelabel~s and footnotes. (These weaknesses are due to 
-weaknesses of \LaTeX's ~\marginpar~ mechanism that Stephan 
-used for ~\linelabel~.) So we changed some ~lineno.sty~ 
-definitions in some extra files, which moreover offered new 
-features. We sent these files to Stephan, hoping he would take 
-the changes into ~lineno.sty~. However, he was too short of time. 
-
-Writing a TUGboat article on Ednotes in 2004, we hoped to 
-reduce the number of files in the Ednotes bundle and so asked 
-Stephan again. Now he generously offered maintenance to me, so 
-I could execute the changes on my own. 
-
-The improvements are as follows: 
-\begin{itemize}\item 
-[(i)]   Footnotes placement approaches intentions better 
-(footnotes formerly liked to pile up at late pages). 
-\item 
-[(ii)]  The number of ~\linelabel~s in one paragraph is no longer 
-limited to 18. 
-\item 
-[(iii)] ~\pagebreak~, ~\nopagebreak~, ~\vspace~, and the star 
-and optional versions of ~\\~ work as one would expect 
-(section_\ref{s:MVadj}).                                   %% Added for v4.1
-\item 
-[(iv)]  A command is offered which chooses the first line number 
-to be printed in the margin 
-(subsection_\ref{ss:Mod}).                                 %% Added for v4.1
-\item 
-[(v)]   (New v4.1) \LaTeX\ tabular environments (optionally) 
-get line numbers as well, and you can refer to them in the 
-usual automatic way. (It may be considered a shortcoming that, 
-precisely, \emph{rows} are numbered, not lines.---See 
-subsection_\ref{ss:Tab}.) 
-\item 
-[(vi)]  We are moving towards referring to math items 
-(subsection_\ref{ss:MathRef} and the hooks in 
-subsection_\ref{ss:LL}). 
-(/New v4.1) 
-\end{itemize}
-(Thanks to Stephan for making this possible!)
-
-
-Ednotes moreover profits from Stephan's offer with regard 
-to the documentation of our code which yielded these 
-improvements formerly. This documentation now becomes 
-printable, being part of the ~lineno.sty~ documentation. 
-
-Of course, Stephan's previous ~lineno.sty~ versions were a great 
-and ingenious work and exhibit greatest \TeX pertise. I never 
-could have done this. I learnt a lot in studying the code when 
-Christian pointed out strange output results and error 
-messages, and there are still large portions of ~lineno.sty~ 
-which I don't understand (consider only pagewise numbering of 
-lines). Fortunately, Stephan has offered future help if 
-needed.---My code for attaching line numbers to \emph{tabular 
-environments} (as mentioned above, now still in 
-~edtable.sty~) %%                                                      %% TODO
-developed from macros which Stephan and Christian experimented 
-with in December 2002. Stephan built the basics. 
-(However, I then became too proud to follow his advice only to 
-use and modify ~longtable.sty~.)
-
-There are some issues concerning use of counters on which I 
-don't agree with Stephan and where I would like to change the 
-code if ~lineno.sty~ is ``mine'' as Stephan offered. However, 
-Stephan is afraid of compatibility problems from which, in 
-particular, his wife could suffer in the near future. So he 
-demanded that I change as little as possible for my first 
-version. Instead of executing changes that I plan I just offer 
-my opinions at the single occasions. I hope to get in touch 
-this way with users who consider subtle features vital which I 
-consider strange. 
-
-On the other hand, the sections on improvements of the 
-implementation have been blown up very much and may be tiring 
-and litte understandable for mere \emph{users}. These users 
-may profit from the present presentation just by jumping to 
-sections_\ref{s:Opts} and_\ref{s:UserCmds}. There is a user's 
-guide ulineno.tex which may be even more helpful, but it has 
-not been updated for a while.                                        %% TODO

-Basic code of \texttt{lineno.sty} \scs{output}
-\unskip}\label{ss:output} 
-
-The line numbers have to be attached by the output
-routine.  We simply set the ~\interlinepenalty~ to $-100000$.
-The output routine will be called after each line in the
-paragraph,  except the last,  where we trigger by ~\par~.
-The ~\linenopenalty~ is small enough to compensate a bunch of
-penalties (e.g., with ~\samepage~).
-
-(New v3.04)            Longtable uses 
-~\penalty~$-30000$.  The lineno penalty range was 
-shrunk to $-188000 \dots -32000$.  (/New v3.04)
-(New v4.00) New values are listed below (11111f.). (/New v4.00) 
-\begin{code}\begin{verbatim}

-(UL)                              Hm. It is never needed below 
-that this is a counter. ~\def\linenopenalty{-100000\relax}~ 
-would do. (I guess this consumes more memory, but it 
-is more important to save counters than to save memory.) 
-I was frightened by ~-\linenopenalty~ below, but indeed 
-\TeX\ interprets the string ~--100000~ as 100000. 
-Has any user or extension package writer ever called 
-~\linenopenalty=xxx~, or could I really change this?---The 
-counter is somewhat faster than the macro. Together with the 
-compatibility question this seems to support keeping the 
-counter. (???)

-\begin{code}\begin{verbatim}
-\mathchardef\linenopenaltypar=32000

-\end{code}
-So let's make a hook to ~\output~,  the direct way. The \LaTeX\ 
-macro ~\@reinserts~ puts the footnotes back on the page.
-
-(New v3.01)                ~\@reinserts~ badly
-screws up split footnotes.  The bottom part is
-still on the recent contributions list, and the
-top part will be put back there after the bottom
-part. Thus, since lineno.sty does not play well
-with ~\inserts~ anyway, we can safely experiment
-with ~\holdinginserts~, without making things
-much worse.    
-
-Or that's what I thought, but:  Just activating
-~\holdinginserts~ while doing the ~\par~ will
-not do the trick:  The ~\output~ routine may be
-called for a real page break before all line
-numbers are done, and how can we get control
-over ~\holdinginserts~ at that point?
-
-Let's try this:  When the ~\output~ routine is
-run with ~\holdinginserts=3~ for a real page
-break, then we reset ~\holdinginserts~ and
-restart ~\output~.
-
-Then, again, how do we keep the remaining
-~\inserts~ while doing further line numbers? 
-
-If we find ~\holdinginserts~=$-3$ we activate it again 
-after doing ~\output~.             (/New v3.01)
-
-(New v3.02)                    To work with
-multicol.sty, the original output routine is now
-called indirectly, instead of being replaced.
-When multicol.sty changes ~\output~, it is a
-toks register, not the real thing. (/New v3.02)
-
-(New v4.00)               Two further complications are added. 
-\begin{itemize}\item
-[(i)]  Problems with footnotes formerly resulted from 
-\LaTeX's ~\@reinserts~ in ~\@specialoutput~ which Stephan's 
-~\linelabel~ called via the ~\marginpar~ mechanism. 
-\item
-[(ii)] \LaTeX\ commands using ~\vadjust~ formerly didn't work 
-as one would have hoped. The problem is as follows: 
-Printing the line number results from 
-a box that the output routine inserts at the place of the 
-~\interlinepenalty~. ~\vadjust~ items appear \emph{above} the 
-~\interlinepenalty~ (\TeX book p._105). So ~\pagebreak~, e.g., 
-formerly sent the line number to the next page, while the 
-penalty from ~\nopagebreak~ could not tie the following line, 
-since it was screened off by the line number box.---Our trick 
-is putting the ~\vadjust~ items into a list macro from which 
-the output routine transfers them into the vertical list, 
-below the line number box. 
-\end{itemize}
-In this case_(ii), like in case_(i), footnotes would suffer 
-if ~\holdinginserts~ were non-positive. Indeed, in both 
-cases_(i) and_(ii) we tackle the footnote problem by extending 
-that part of Stephan's output routine that is active when 
-~\holdinginserts~ is positive. This extension writes the line 
-number ~\newlabel~ to the .aux file (which was formerly done 
-under $~\holdinginserts~=-3$) and handles the ~\vadjust~ 
-items.---To trigger ~\output~ and its ~\linelabel~ or, resp., 
-~\vadjust~ part, the list of signal penalties started 
-immediately before is increased here (first for ~\linelabel~, 
-second for postponed ~\vadjust~ items):

-(/New v4.00) (New v4.2) David Kastrup urges to use a private 
-name instead of ~\the\output~ (LaTeX-L-list). Otherwise an 
-~\output~ routine loaded later and using ~\newtoks\output~ 
-again may get lost entirely. So we change use of ~\@LN@output~,

-\textit{More on dealing with output routines from other 
-packages:} 
-Since ~lineno.sty~'s output routine is called at least once 
-for each output line, I think it should be in \TeX's 
-original ~\output~, while output routines dealing with 
-building pages and with floats etc.\ should be filled into 
-registers addressed by ~\output~ after ~\newtoks\output~. 
-Therefore                                                  \begin{enumerate}
-\item 
-~tameflts.sty~ should be loaded \emph{after} ~lineno.sty~; 
-\item 
-if a class changes ~\output~ (APS journal class revtex4, 
-e.g.), ~lineno.sty~ should be loaded by ~\RequirePackage~ 
-[here presumably following some options in 
-brackets]~{lineno}~ \emph{preceding} ~\documentclass~. 
-\item 
-If you actually maintain such a class, please consider 
-loading ~lineno.sty~ on some draft option. The bunch of 
-lineno's package options may be a problem, but perhaps the 
-purpose of your class is offering only very few of lineno's 
-options anyway, maybe just one. 
-\end{enumerate} 
-The latter may also be needed with classes that don't follow 
-David Kastrup's rule on changing ~\output~.

-\subsection{%
-\scs{MakeLineNo}: Actually attach line number 
-\unskip}\label{ss:MLN} 
-
-We have to return all the page to the current page, and
-add a box with the line number, without adding
-breakpoints, glue or space.  The depth of our line number
-should be equal to the previous depth of the page, in
-case the page breaks here,  and the box has to be moved up
-by that depth.  
-
-The ~\interlinepenalty~ comes after the ~\vadjust~ from a
-~\linelabel~,  so we increment the line number \emph{after}
-printing it. The macro ~\makeLineNumber~ produces the
-text of the line number, see section \ref{appearance}.
-
-(UL)                        I needed a while to understand 
-the sentence on incrementing. Correctly: writing the 
-~\newlabel~ to the .aux file is triggered by the signal 
-penalty that ~\end@float~ inserts via ~\vadjust~. 
-However, this could be changed by our new ~\PostponeVadjust~. 
-After ~\c@linenumber~ has been introduced as a \LaTeX\ 
-counter, it might be preferable that it behaved like standard 
-\LaTeX\ counters which are incremented shortly before printing. 
-But this may be of little practical relevance in this case, 
-as ~\c@linenumber~ is driven in a very non-standard 
-way.---However still, this behaviour of ~\c@linenumber~ 
-generates a problem with our ~edtable.sty~. 
-(/UL). 
-
-Finally we put in the natural ~\interlinepenalty~, except
-after the last line. 
-
-(New v3.10) Frank Mittelbach points out that box255 may be 
-less deep than the last box inside, so he proposes to 
-measure the page depth with ~\boxmaxdepth=\maxdimen~.
-(/New v3.10)
-
-(UL, New v4.00)               We also resume the matter of 
-~\vadjust~ items that was started in section_\ref{ss:output}. 
-
-\TeX\ puts only nonzero interline 
-penalties into the vertical list (\TeX book p._105), while 
-~lineno.sty~ formerly replaced the signal interline penalty by 
-something closing with an explicit penalty of the value that 
-the interline penalty would have without ~lineno.sty~. 
-This is usually 0. Now, explicit vertical penalties can be 
-very nasty with respect to ~\nopagebreak~, e.g., a low (even 
-positive) ~\widowpenalty~ may force a widow where you 
-explicitly tried to forbid it by ~\nopagebreak~ 
-(see explanation soon below). 
-The ~\nopagebreak~ we create here would never work if all 
-those zero penalties were present.---On 
-the other hand, we cannot just omit Stephan's zero penalties, 
-because \TeX\ puts a penalty of 10000 after what ~lineno.sty~ 
-inserts (\TeX book p._125). This penalty must be overridden 
-to allow page breaks between ordinary lines. To revive 
-~\nopagebreak~, we therefore replace those zero (or low) 
-penalties by penalties that the user demanded by 
-~\nopagebreak~.---This mechanism is not perfect and does not 
-exactly restore the original \LaTeX\ working of ~\pagebreak~ 
-and ~\nopagebreak~. Viz., if there are several vertical 
-penalties after a line which were produced by closely sitting 
-~\[no]pagebreak~s, without ~lineno.sty~ the lowest penalty would 
-be effective (cf._\TeX book exercise_14.10). Our mechanism, by 
-contrast, chooses the \emph{last} user-set penalty of the line 
-as the effective one. It would not be very difficult to come 
-more close to the original mechanism, but until someone urges 
-us we will cling to the present simple way. You may consider an 
-advantage of the difference between our mechanism and the 
-original one that the user here can actually override low 
-penalties by ~\nopagebreak~, which may be what a lay \LaTeX\ 
-user would expect.

-Difficult, if you think about it.  The number has to be

-
-~\makeLineNumber~ gets a hook to log the line and page
-number to the aux-file.  Another hook tries to find out
-what the page offset is, and subtracts it from the counter
-~\c@linenumber~.  Additionally, the switch
-~\ifoddNumberedPage~ is set true for odd numbered pages,
-false otherwise.

-(/New v4.2)                I had thought of offering more

-~\c@LN@truepage~ by ~\stepcounter{page}~. E.g., she might

-it for list macros anyway. 
-(/UL) (/New v4.00) 
-
-From the aux-file we get one macro ~\LN@P~<page> for each
-page with line numbers on it.  This macro calls four other
-macros with one argument each.  These macros are
-dynamically defined to do tests and actions, to find out
-on which page the current line number is located.
-
-We need sort of a pointer to the first page with line
-numbers, initiallized to point to nothing:
-\begin{code}\begin{verbatim}
-\def\LastNumberedPage{first} 
-\def\LN@Pfirst{\nextLN\relax}
-\end{verbatim}

-The four dynamic macros are initiallized to reproduce
-themselves in an ~\xdef~
-\begin{code}\begin{verbatim}
-\let\lastLN\relax  % compare to last line on this page
-\let\firstLN\relax % compare to first line on this page
-\let\pageLN\relax  % get the page number, compute the linenumber
-\let\nextLN\relax  % move to the next page
-\end{verbatim}
-\end{code}
-During the end-document run through the aux-files, we
-disable ~\@LN~.  I may put in a check here later, to give
-a rerun recommendation.  
-\begin{code}\begin{verbatim}
-\AtEndDocument{\let\@LN\@gobbletwo}
-\end{verbatim}
-\end{code}
-Now, this is the tricky part.  First of all, the whole
-definition of ~\@LN~ is grouped, to avoid accumulation
-on the save stack. Somehow ~\csname~<cs>~\endcsname~ pushes
-an entry, which stays after an ~\xdef~ to that <cs>.
-
-If ~\LN@P~<page> is undefined, initialize it with the
-current page and line number, with the
-\emph{pointer-to-the-next-page} pointing to nothing.  And
-the macro for the previous page will be redefined to point
-to the current one. 
-
-If the macro for the current page already exists, just
-redefine the \emph{last-line-number} entry.
-
-Finally, save the current page number, to get the pointer to the

-~\gotNumberedPage~ with four arguments: the first line
-number on this column, the page number, the column 
-number, and the first line on the page.

-The last heading formerly was the heading of what is now

-said to execute user commands only. This was wrong already

-Extended referencing to line numbers. (v4.2)
-\unskip}
-This subsection explains and declares package option ~addpageno~.   %% v4.31
-
-If a line to whose number you refer by ~\ref~ is not on the 
-present page, it may be useful to add the number of the page 
-on which the line occurs---and perhaps it should not be added 
-otherwise. In general, you could use the Standard \LaTeX\ 
-package varioref for this. However, the latter usually 
-produces verbose output like `on the preceding page'---
-unless costumized---, while in critical editions, e.g., one 
-may prefer just adding the page number and some mark on the 
-left of the line number, irrespectively of how far the page is 
-apart etc. To support this, package option ~addpageno~ 
-provides a command ~\vpagelineref~ to be used in place of 
-~\ref~. This produces, e.g., `34.15' when referring to line_15 
-on page_34 while the present page is not 34. You can customize 
-the outcome, see the package file ~vplref.sty~ where the code 
-and further details are. You may conceive of 
-~\vpagelineref~ as a certain customization of varioref's 
-~\vref~. 
-
-This implies that option ~addpageno~ requires the files 
-~vplref.sty~ and ~varioref.sty~. ~addpageno~ automatically 
-loads both of them. Yet you can also load ~varioref.sty~ 
-on your own to use its package options. 
-
-Of course, you might better introduce a shorter command name 
-for ~\vpagelineref~ for your work, while we cannot predict 
-here what shorthand will fit your work. E.g., 
-~\newcommand{\lref}{\vpagelineref}~.
-
-If you really want to add the page number in \emph{any} case, 
-use, e.g., some ~\myref~ instead of ~\ref~, after 
-\[~newcommand*{\myref}{\pageref{#1}.\ref{#1}}~\] 
-or what you like. You don't need the ~addpageno~ option in 
-this case.

-~addpageno~ is due to a suggestion by Sergei Mariev.

-Arrays, tabular environments (Revised v4.11)
-\unskip}\label{ss:Tab} 
-
-This subsection explains and declares package options               %% v4.31
-~edtable~, ~longtable~, and ~nolongtablepatch~.
-
-The standard \LaTeX\ tabular environments come as single 
-boxes, so the ~lineno.sty~ versions before v4.00 treated them as 
-(parts of) single lines, printing (at most) one line number 
-beside each and stepping the line number counter once only. 
-Moreover, ~\linelabel~s got lost. Of course, tables are 
-usually so high that you will want to treat each row like a 
-line. (Christian Tapp even desires that the lines of table 
-entries belonging to a single row are treated like ordinary 
-lines.) Footnotes get lost in such environments as well, which 
-was bad for ~ednotes.sty~.
-
-We provide adjustments to count lines, print their numbers 
-etc.\ as desired at least for \emph{some} \LaTeX\ tabular 
-environments. (Like with other details, ``some'' is to some 
-extent explained in ~edtable.sty~.) We do this similarly as 
-with option ~mathrefs~ before.               We leave code 
-and explanations in the separate package ~edtable.sty~. 
-(For wizards: this package provides adjustments for 
-~ednotes.sty~ as well. However, in the present case we don't try 
-to avoid them unless ~ednotes.sty~ is loaded.) 
-Package option ~edtable~ 
-defines---by loading ~edtable.sty~---an environment ~{edtable}~ 
-which is able to change some \LaTeX\ tabular environments 
-with the desired effects. (v4.11: ~edtable.sty~ v1.3 counts 
-\LaTeX's ~{array}~ [etc.\@] as a ``tabular environment'' as 
-well.) 
-
-The ~{edtable}~ environment doesn't help with ~longtable.sty~, 
-however. To make up for this, ~{longtable}~ is adjusted in a 
-different way---and this happens only when another ~lineno.sty~ 
-option ~longtable~ is called. In this case, option ~edtable~ 
-needn't be called explicitly: option ~longtable~ works as if 
-~edtable~ had been called. 
-
-Now, we are convinced that vertical spacing around 
-~{longtable}~ works wrongly---see \LaTeX\ bugs database 
-tools/3180 and 3485, or see explanations in the package 
-~ltabptch.sty~ (which is to be obtained from CTAN folder
-\path{macros/latex/ltabptch}). Our conviction is so strong
-that the ~longtable~ option loads---after ~longtable.sty~---the
-patch package ~ltabptch.sty~. If the user doesn't want this
-(maybe preferring her own arrangement with the vertical 
-spacing), she can forbid it by calling ~nolongtablepatch~. 
-
-The following code just collects some choices, which are 
-then executed in section_\ref{ss:ExOpt}. We use an ~\if...~ 
-without ~\newif~ since ~\if...true~ and ~\if...false~ 
-would occur at most two times and only within the present 
-package. (~\AtEndOfClass{\RequirePackage{edtable}}~ 
-could be used instead, I just overlooked this. Now I don't 
-change it because it allows to change the version requirement 
-at one place only.)

-These ~\global~s are just to remind that

-to their left ends in a way which should work rather

-only if it's guaranteed that a ~\vadjust~ is near.---(UL) 
-Sure? In line numbering mode, probably each ~\vadjust~ 
-coming from a \LaTeX\ command should be ~\PostponeVadjust~. 
-~\marginpar~s and floats seem to be the only cases which 
-are not explicitly dealt with in the present section. 
-This would be a way to avoid ~\@LN@nobreaktrue~! 
-Of course, the ~\vadjust~s that the present package uses

-~\@tempa~ will now become a two place macro which adds first

-~\fi~ to the left of second argument. As long as we need it, 
-we can't use the star form of ~\DeclareRobustCommand~ or

-Now for the main theme of the section. 
-The next lines assume that ~\vspace~, ~\pagebreak~, and 
-~\nopagebreak~ use ~\vadjust~ whenever they occur outside 
-vertical mode; moreover, that they don't directly read 
-an argument. Indeed ~\pagebreak~ and ~\nopagebreak~ first

-~\\~, however, uses ~\vadjust~ only in star or optional form. 
-We relax independency of implementation in assuming 
-that ~\@normalcr~ is the fragile version of ~\\~

-[|\switchlinenumbers*]                                                \ \par
-Causes margin switching in pagewise modes. With the
-star,  put the line numbers on the inner margin.

-\item
-[|\rightlinenumbers*]                                                 \ \par
-Set the line numbers in the left/right margin. With the
-star this works for both modes of operation, without
-the star only for the currently selected mode. 
-\item
-[|\runningpagewiselinenumbers]                                        \ \par
-When using the pagewise line number mode,  do not
-subtract the page offset.  This results in running
-line numbers again,  but with the possibility to switch
-margins.  Be careful when doing line number
-referencing,  this mode status must be the same while
-setting the paragraph and during references.
-\item
-[|\realpagewiselinenumbers]                                           \ \par
-Reverses the effect of ~\runningpagewiselinenumbers~.
-\item
-[|\modulolinenumbers[\NL]                                             \ \par
-Give a number only to lines which are multiples of
-~[~<number>~]~.  If <number> is not specified, the
-current value in the counter ~linenumbermodulo~ is
-retained.  <number>=1 turns this off without changing
-~linenumbermodulo~.  The counter is initialized to 5.
-\item
-[|\modulolinenumbers*[\NL]                                            \ \par 
-Like ~\modulolinenumbers~, the only difference being 
-that the first line number after a ~\linenumbers~ 
-(or ~\runninglinenumbers~, ~\pagewiselinenumbers~, 
-~\quotelinenumbers~) is printed regardless of the 
-modulo---yet `1' is printed only after (or \dots) 
-~\firstlinenumber{1}~. 
-This also applies to the first line of a 
-~{linenumbers}~ or respective environment. 
-See subsection_\ref{ss:Mod} for another explanation. 
-The behaviour may be unsatisfactory with pagewise 
-line-numbering. 
-\item
-[|\firstlinenumber]                                                   \ \par 
-~\firstlinenumber{~<filino>~}~ brings about that 
-(after it) line numbers less than <filino> do 
-\emph{not} appear in the margin. Moreover, with 
-~\modulolinenumbers[~<number>~]~, just the line 
-numbers which are <filino> plus a multiple of 
-<number> are printed.---If you had 
-~\firstlinenumber{~<pos>~}~ with some $\mbox{<pos>}>0$ 
-and want to switch to printing multiples of, e.g.,

-\maketitle
-\section*{Preface}
-
-\texttt{lineno.sty} is a macro package made by 
-Stephan~I.~B\"ottcher for attaching line numbers to 
-\LaTeX\ documents. Some people have used it for revising 
-submittings in collaboration with referees or co-authors. 
-Documentations are nowadays preferred to be in 
-Adobe's \texttt{PDF}---so \texttt{lineno.sty}'s 
-documentation is \lcurl{lineno/lineno.pdf\,.}
-
-\texttt{ednotes.sty} uses \texttt{lineno.sty} for critical 
-editions, combining it with Alexander~I.~Rozhenko's 
-\texttt{manyfoot.sty}---this was Christian Tapp's idea, 
-who then hired me for adding the \TeX nical details. 
-In doing this, I had to change some internals of 
-\texttt{lineno.sty}, so Stephan transferred maintenance 
-to me; then some of my macro files that I originally had 
-made for \texttt{ednotes.sty} wandered into the 
-\texttt{lineno} directory of CTAN---because they turned 
-out not to need \texttt{ednotes.sty}, 
-just to work as extensions of \texttt{lineno.sty}\,. 
-
-Now, I haven't had the time for making \texttt{.dtx} versions 
-of the \texttt{.sty} files for \texttt{ednotes}. 
-Therefore, ordinary \texttt{.pdf} documentation for 
-the remaining \texttt{.sty} files of \lcurl{lineno/}
-is missing. 
-What you see here is nothing but a somewhat structured listing 
-of the additional \texttt{.txt} and \texttt{.sty} files in 
-\texttt{PDF}, deriving from the \texttt{verbatim} package and 
-its \cs{verbatiminput} command. I hope the high quality 
-(scalable) output is worth it.

-\section{When to use \lineno.sty}
-
-The primary use of \lineno.sty is to get line numbers in your LaTeX
-document.  \lineno.sty directly supports line numbers in various
-modes, and if you have any wishes that are not directly supported,
-chances are good that \lineno.sty can be adapted to do it.  And if it
-turns out to be difficult with \lineno.sty, then it will be even more
-difficult without.
-
-There is one class of cases however, where \lineno.sty is not the most
-appropriate tool.  When your text already comes in lines, like source
-listings, tables, poetry,  then \lineno.sty will propably do the job,
-but other tools could do it much more efficiently.
-
-\lineno.sty can only number lines in the main text.  Lines in any kind
-of boxes cannot be numbered.  But see section \ref{sec:ilineno} below.
-
-\lineno.sty is especially useful when the text is broken into lines by
-\TeX\ itself.  In this case, the task to attach line numbers is not
-easy, and a tool like \lineno.sty has good chances to break when used
-together with other packages.
-
-On the other hand, \lineno.sty proved to be quite stable, and I did
-not get any reports of complete failure yet.
-
-With \lineno.sty, you can refer to the line numbers via \LaTeX s
-~\ref~ and ~\pageref~ macros.
-
-There are other applications, not directly related to line numbering.
-Whenever you want to attach something to your text, after a paragraph
-was broken into lines, across pagebreaks, lineno may do the job.
-
-\begin{bframe}
-  Say, you need a frame around some text, but the text should be able
-  to break across pages, \lineno.sty can be used to draw rules on both
-  margins, which can be completed at the top and bottom by some
-  special environment, see section\,\,\ref{sec:bframe}.
-\end{bframe}
-
-There may be cases, where other packages do a better job, e.g.,
-\url{CTAN:macros/latex/contrib/supported/numline}.
-
-
-\section{Where to get \lineno.sty}
-
-\lineno.sty is available on the \emph{Comprehensive TeX Archive
-  Network} (CTAN), e.g, \url{ftp:// ftp.tex.ac.uk/ tex-archive/
-  macros/ latex/ contrib/ supported/ lineno/ lineno.sty}.
-
-The home of \lineno.sty is \url{http:// www.nevis.columbia.edu/
-  ~stephan/ tex/ #lineno}.  Here you can get the latest version.
-
-\end{runninglinenumbers}
-
-\section{How to use \lineno.sty}
-
-As any other \LaTeXe\ package, you need to load it with
-\begin{quote}
-   ~\usepackage[~<options>~]{lineno}~
-\end{quote}
-
-\subsection{Package options}
-
-The available <options> are:
-\begin{description}
-
-\item[\texttt{[left]}:]  Put the line numbers into the left margin
-  (default). 
-
-\item[\texttt{[right]}:]  Put the line numbers into the right margin.
-
-\item[\texttt{[switch]}:]  Put the line numbers into the outer margin
-  (left on even numbered pager, right on odd numbered pages).
-
-\item[\texttt{[switch*]}:]  Put the line numbers into the inner
-  margin.
-  
-\item[\texttt{[pagewise]}:] Number the lines from 1 on each page.
-
-\item[\texttt{[running]}:]  Continuously number the lines (default).
-  
-\item[\texttt{[modulo]}:] Print line numbers only if they are
-  multiples of five.
-
-\item[\texttt{[mathlines]}:]  When using the ~{linenomath}~
-  environment for display math, put line numbers also on the lines of
-  the display.
-
-\item[\texttt{[displaymath]}:]  Automatically wrap the standard LaTeX
-  display math environments in ~{linenomath}~.
-
-  \begin{itshape}
-    Change from v2 to v3:  ~[mathlines]~ was called ~[displaymath]~
-    before, and ~[displaymath]~ was ~\usepacke{mlineno}~.
-  \end{itshape}
-  
-\end{description}
-All effects of these option can also be obtained by calling certain
-macros later in the document, except for ~[displaymath]~.
-
-\subsection{How to turn on line numbering}
-
-The line numbering is not activated by default.  If you want line
-numbers, you have to turn it on.  The simplest way is to say
-\begin{quote}
-    ~\linenumbers~
-\end{quote}
-This will turn on line numbers within the current group, according to
-the currently selected mode.  If you do it right at the beginning, the
-whole document will be numbered.
-
-~\linenumbers~ takes effect only when a paragraph is finished.  This
-is important if you use ~\linenumbers~ for a single paragraph only.
-This will \emph{not} work:
-\begin{quote}\obeylines
-   ~\begingroup~\\%
-   ~\linenumbers~
-     Text of your paragraph.
-   ~\endgroup~
-\end{quote}
-because the ~\endgroup~ terminates the effect of ~\linenumbers~ before
-the paragraph is finished.  The solution is to insert an empty line,
-or an explicit ~\par~ before the ~\endgroup~.
-
-The prefered solution is to use an enviroment:
-\begin{quote}\obeylines
-   ~\begin{linenumbers}~ 
-     Text of your paragraph. 
-   ~\end{linenumbers}~
-\end{quote}
-~\end{linenumbers}~ terminates the paragraph for you.  It will also
-make sure that the next paragraph is not indented, if there is no
-empty line in between.
-
-This form will not finish any preceeding paragraph.  If you do not
-leave an empty line before ~\begin{linenumbers}~, the previous
-  paragraph may also get line numbers (this is not true after a list
-  environment).
-
-A quite esoteric form to number a single paragraph is:
-\begin{quote}\obeylines
-     Text of your paragraph.
-     ~{\linenumbers\par}~
-\end{quote}
-Here, the ~\linenumbers~ is turned on in a group that just executes
-the ~\par~ to terminate the previous paragraph.  Only this paragraph
-will have line numbers. (~\par~ is exactly equivalent to an empty
-line).
-
-
-\subsection{How to turn off line numbering}
-
-You do not usualy turn of line numbering explicitly, but rather
-restrict line numbering to a group or an environment.  However, you
-can turn it off with the command
-\begin{quote}
-   ~\nolinenumbers~
-\end{quote}
-This macro can also be used as an environment.  The same restrictions
-apply as for ~\linenumbers~.
-
-
-\section{Numbering modes}
-
-Attaching line numbers after \TeX\ has broken the paragraph into lines
-is already quite a difficult job for \TeX.  Why?  Because \TeX\ does
-not normally give you any control after line breaking.  \lineno.sty
-does it by pretending that the current page ends after each and every
-line.  This keeps \TeX\ quite busy, but works.
-
-Often, you want the line numbers to depend on the page they finally end
-up.  E.g., you want the numbers to start with~ ~1 one each new page,
-or you want them to appear on the outer margins in twoside mode.  This
-is an almost impossible demand, but \lineno.sty can do it, at some
-cost, in terms of computing time, memory, and disk space.  \lineno.sty
-needs to write a note into the auxiliary file for each line in the
-numbered part of the text, and \TeX\ keeps some memory for each page,
-and all that takes some computation time to figure out on which page
-the line was in the last \LaTeX\ run.
-
-Thus, there are two basic numbering modes
-\begin{enumerate}
-  
-\item \emph{Running} line numbers.  The numbers run continuously along
-  the document, without considering page breaks.  
-  
-  The line numbers can be reset, or preset at any point in the
-  document (except within a paragraph).  Margin switching (or any
-  other dependence on the page breaks) is not possible.
-  
-\item \emph{Pagewise} line numbers.  The lines on each page are
-  numbered from one.  Automatic margin switching is possible.
-
-  \emph{Running} mode can be simulated in pagewise mode, to get
-  automatic margin switching with continuous line numbers, but without
-  the ability to reset/preset the line numbers anywhere in the
-  document.  
-  
-  Any feature that depends on the page breaks must use this mode.
-
-\end{enumerate}
-
-\begin{runninglinenumbers*}
-
-\subsection{\emph{Running} line numbers}
-
-This is the default mode of operation.  The lines of your text are
-numbered continuously across page breaks.  
-
-You cannot get automatic margin switching in this mode, because at the
-time when the line numbers are attached, it is not yet decided on
-which page the line will end up.  However, you can simulate continuous
-line numbers in \emph{pagewise} mode (see below), where margin
-switching becomes possible.
-
-You get this mode by
-\begin{itemize}\raggedright
-\item \emph{not} specifying any of the package options
-  ~[switch,pagewise]~,
-\item specifying the package option ~[running]~,
-\item give the command ~\setrunninglinenumbers~ in the document, or
-\item turn on line numbering with ~\runninglinenumbers~ or
-  ~\begin{runninglinenumbers}~. 
-\end{itemize}
-
-\subsubsection{Reseting or setting the line number}
-
-You can reset the line number with
-\begin{quote}
-  ~\resetlinenumber[~<number>~]~
-\end{quote}
-where the default is to reset the line number to one.
-
-Alternatively, you can give the line number in an optional argument to
-any command that turns on the line numbering in this mode:
-\begin{quote}\obeylines
-  ~\linenumbers[~<number>~]~ 
-  ~\runninglinenumbers[~<number>~]~ 
-  ~\begin{linenumbers}[~<number>~]~
-  ~\begin{runninglinenumbers}[~<number>~]~
-\end{quote}
-or reset the line number to 1 with any of the following:
-\begin{quote}\obeylines
-  ~\linenumbers*~ 
-  ~\runninglinenumbers*~ 
-  ~\begin{linenumbers*}~
-  ~\begin{linenumbers}*~
-  ~\begin{runninglinenumbers*}~
-  ~\begin{runninglinenumbers}*~
-\end{quote}
-This section of the manual is enclosed in
-\begin{quote}\obeylines
-  ~\begin{runninglinenumbers*}~
-  ~\end{runninglinenumbers*}~
-\end{quote}
-\end{runninglinenumbers*}
-
-
-\begin{pagewiselinenumbers}
-
-\subsection{\emph{Pagewise} line numbers}
-
-Basically, this mode prints line numbers starting with 1 on top of
-each page, counting only lines where this mode is active.  If you
-turn on this mode in the middle of a page, the numbers start with 1
-at that point.
-
-The \emph{pagewise} mode of operation is quite a bit more work for
-\TeX.  When the line numbers are printed, \TeX\ does not know on which
-page the current line will go.  To get \emph{pagewise} mode working,
-\LaTeX\ has to remember on which page the line went in a previous run.
-This information is written into the ~.aux~ file, and like a table of
-contents, you will not see the numbers until you run \LaTeX\ at least
-twice on the document.  Sometimes the information in the ~.aux~ file
-becomes invalid in a way that causes \lineno.sty to hang.  In such a
-case you'll have to delete all ~.aux~ files of the document to get it
-going again.
-
-You get this mode by
-\begin{itemize}\raggedright
-\item specifying the package option
-  ~[pagewise]~, but not ~[running]~,
-\item give the command ~\setpagewiselinenumbers~ in the document, or
-\item turn on line numbering with ~\pagewiselinenumbers~ or
-  ~\begin{pagewiselinenumbers}~. 
-\end{itemize}
-
-You cannot reset or preset the line numbers in \emph{pagewise} mode.
-This mode uses a different counter than \emph{running} mode.  You can
-switch between the mode, and the \emph{running} numbers will continue
-where they left of, unless you reset the counter.
-
-\subsubsection{Margin switching}
-
-As a side effect of all the business to find out on which page the lines
-end up, margin switching becomes possible.  It is now possible to
-print the line number differently on odd and even pages.  The command
-\begin{quote}
-  ~\switchlinenumbers~
-\end{quote}
-will cause the line numbers to be printed on the outer margins, on the
-right side for odd pages, and on the left side for even numbered
-pages.  If you add a star, the numbers go on the inner margins
-\begin{quote}
-  ~\switchlinenumbers*~
-\end{quote}
-You can achieve the same effect by specifying the package
-option ~[switch]~ or ~[switch*]~ together with ~[pagewise]~. 
-
-Margin switching is independent of any ~[twoside]~ option of the
-document class.
-
-\subsubsection{\emph{Running} mode with margin switching}
-
-Margin switching is not possible in \emph{running} mode, but you can
-abuse the pagewise mode to produce continuous line numbers.  This mode
-is activated with the command
-\begin{quote}
-  ~\runningpagewiselinenumbers~
-\end{quote}
-It is not possible to reset the line number counter for this mode, the
-lines will be numbered starting from one at the beginning of the
-document, and continue.  You can switch back to real pagewise mode with
-\begin{quote}
-  ~\realpagewiselinenumbers~
-\end{quote}
-but when you resume \emph{running-pagewise}, the numbers will not
-continue where they left off, but jump by the number of lines that
-were numbered \emph{real-pagewise}.
-
-The package options ~[switch]~ and ~[switch*]~ will turn on
-\emph{running pagewise} mode with margin switching, unless you also
-specify ~[pagewise]~.
-
-Finally, if you give these options together with ~[running]~, like
-\begin{quote}
-  ~\usepackage[switch,pagewise,running]{lineno}~
-\end{quote}
-the mode is set to plain \emph{running} line numbers, but later in
-your document, if you say ~\pagewiselinenumbers~, the setings of the
-~[switch]~ and ~[pagewise]~ options will take effect.
-
-\subsubsection{Page numbers}
-
-Any pages that contain \emph{pagewise} numbered lines must have a
-different page number.  This may cause trouble with titlepages or
-simmilar fudging with the page number counter in the document.  (I am
-talking about ~\c@page~ or ~\count 0~ here, not ~\thepage~).
-
-If you get strange errors, like \emph{``the use of} ~\nextLN~
-\emph{does not match its definition''}, you should first delete all
-~.aux~ files, and rerun \LaTeX\ several times.  If the error does not
-reappear, fine, else check your page numbers, including those that are
-not printed.  You may use \emph{running} line numbers on your
-titlepages, since the page boundaries are predefined, usually.
-
-\end{pagewiselinenumbers}
-
-\begin{linenumbers*}
-
-\subsection{Margin selection}
-
-In any mode you can select a fixed margin on which the numbers shall
-be printed.  You can either give a package option ~[left]~ or
-~[right]~, or change the margin within the document with
-\begin{quote}\obeylines
-  ~\leftlinenumbers~
-\rightlinenumbers
-  ~\rightlinenumbers~
-\end{quote}
-\rightlinenumbers
-Neither of these commands actually turns on line numbering.  The
-margin setting is changed for the currently selected mode
-\emph{running} or \emph{pagewise}.  If you want to set the margin for
-both modes, append a star
-\begin{quote}\obeylines
-  ~\leftlinenumbers*~
-  ~\rightlinenumbers*~
-\end{quote}
-The default is ~\leftlinenumbers*~.
-
-\end{linenumbers*}
-
-
-\subsection{Summary of mode selection commands}
-
-The following commands change the major line numbering mode.
-\begin{description}\itemsep=0pt\parskip=0pt
-\item [|\setrunninglinenumbers]
-\item [|\setpagewiselinenumbers] \leavevmode\\
-  set the current mode, without activating or deactivating line
-  numbering. 
-\item [|\runninglinenumbers\texttt{*[\NL}]
-\item [|\pagewiselinenumbers] \leavevmode\\
-  set the current mode and activate line numbering, optionally reset
-  (~*~), or set the line number for \emph{running} mode. 
-\end{description}
-The following commands do not change the major mode, but modify the
-the behaviour of \emph{pagewise} mode
-\begin{description}\itemsep=0pt\parskip=0pt
-\item [|\realpagewiselinenumbers]
-\item [|\runningpagewiselinenumbers] \leavevmode\\
-  select if \emph{pagewise} mode should number continuously, or really
-  pagewise.
-\end{description}
-
-
-\subsection{Summary of margin selection commands}
-
-The following command select into which margin the numbers should be
-printed 
-\begin{description}\itemsep=0pt\parskip=0pt
-\item [|\leftlinenumbers\texttt*]
-\item [|\rightlinenumbers\texttt*] \leavevmode\\
-  put the line numbers in the left/right margin in both modes.
-\item [|\leftlinenumbers]
-\item [|\rightlinenumbers] \leavevmode\\
-  put the line number into the left/right margin in the currently
-  selected mode.
-\item [|\switchlinenumbers] \leavevmode\\
-  put the line numbers into the outer margin, when using
-  \emph{pagewise} mode.
-\item [|\switchlinenumbers\texttt*] \leavevmode\\
-  put the line numbers into the inner margin, when using
-  \emph{pagewise} mode.
-\end{description}

-\begin{linenumbers*}
-\modulolinenumbers[2]
-
-\subsection{Numbering only one in five lines}
-
-You can ask lineno to print the line numbers only if they devide by
-<n>, by saying
-\begin{quote}
-  ~\modulolinenumbers[~<n>~]~
-\end{quote}
-If you omit the optional argument, it will be every fifth line, or
-whatever you used last (the current value of the counter
-~linenumbermodulo~).  You get the same effect by giving the package
-option ~[modulo]~.
-
-If you set <n> to 1, the modulo value is not changed, but modulo
-numbering is turned off.  
-
-Changing the counter ~linenumbermodulo~ does not turn on modulo
-numbering, it just changes the modulo, if it is turned on without the
-optional argument.
-
-This section of the manual is enclosed in
-\begin{quote}
-  ~\begin{linenumbers*}~ \\ 
-  ~\modulolinenumbers[2]~

-\subsection{How the line numbers look like}
-
-This section of the manual is enclosed in
-\begin{quote}
- ~\begin{pagewiselinenumbers}~ \\
- ~\switchlinenumbers~
-
- ~\end{pagewiselinenumbers}~
-\end{quote}
-By default, the line numbers are set in
-\begin{quote}
-  ~\normalfont\tiny\sffamily~
-\end{quote}
-right justified to 10\,pt left of the nominal left edge of the text.
-If the number is to appear on the right margin, it is right justified
-to 20\,pt right of the nominal right edge of the text.
-
-You can easily change that, of course.  The font is defined by the
-macro
-\begin{quote}
-  ~\linenumberfont~
-\end{quote}
-You can redefine it to make the numbers appear in a differnt font
-(with ~\renewcommand~).  I'll say right here in this manual
-\renewcommand\linenumberfont{\normalfont\bfseries\small}
-\begin{quote}
-  ~\renewcommand\linenumberfont{\normalfont\bfseries\small}~
-\end{quote}
-The distance on the left margin can be changed with
-\begin{quote}
-  ~\setlength\linenumbersep{~<distance>~}~
-\end{quote}
-The distance on the right margin is ~\linenumbersep~ plus
-~\linenumberwidth~, both are set to 10\,pt by default.
-Let's do right here
-\setlength\linenumberwidth{1cm}
-\begin{quote}
-  ~\setlength\linenumbersep{1cm}~
-\end{quote}
-I put the command at the end of the paragraph, but it effects the
-whole paragraph, because that is where everything happens: at the end
-of the paragraphs.
-
-The line numbers are printed as arabic numerals, as defined in the
-macro
-\begin{quote}
-  ~\thelinenumber~
-\end{quote}
-for the \LaTeX\ counter ~{linenumber}~.  You can redefine that, as
-for any other \LaTeX\ counter.  E.g.,
-\renewcommand\thelinenumber{\roman{linenumber}}
-\begin{quote}
-  ~\renewcommand\thelinenumber{\roman{linenumber}}~
-\end{quote}
-(For heavy duty line numbering, you should use \LaTeX s internal
-format, e.g., ~\@roman\c@linenumber~.)
-
-\subsubsection{Deeper customization}
-
-The line number is attached to the line by the macro
-\begin{quote}
-  ~\makeLineNumber~
-\end{quote}
-which is expanded inside a zero width ~\hbox~ alligned to the
-origin of the current line (left edge, baselines alligned).  You can
-do anything in this macro.  Let's assume you do not want line numbers
-at all, but just attach something else to each line of text: this is
-the macro to modify.  You can refer to the line number by the macro
-~\LineNumber~, which prints the current value of the counter
-~{linenumber}~, or nothing if \emph{modulo} mode is active, and the
-number does not divide by ~{linenumbermodulo}~.  You should not modify
-this macro when using any form of \emph{pagewise} mode.  At the end of
-this paragraph I put the following
-\begin{runninglinenumbers}
-\renewcommand\makeLineNumber
-   {\hss$\rightarrow$\ \rlap{\hskip\textwidth\ $\leftarrow$}}
-\end{runninglinenumbers}
-\begin{quote}
-  ~\begin{runninglinenumbers}~\\
-  ~\renewcommand\makeLineNumber~\\
-  ~ {\hss$\rightarrow$\ \rlap{\hskip\textwidth\ $\leftarrow$}}~\\
-  ~\end{runninglinenumbers}~
-\end{quote}
-
-Redefining ~\makeLineNumber~ cuts deep into the linenumber mode
-setting.  If you still want to use the basic modes \emph{running} and
-\emph{pagewise} you should go one level up and modify one of the
-following macros, which are called by (or assigned to)
-~\makeLineNumber~ depending on the current mode, and with the counter
-~{linenumber}~ allready adjusted for the current page when using
-\emph{pagewise} mode.
-\begin{quote}\obeylines
-  ~\makeLineNumberRunning~
-  ~\makeLineNumberOdd~
-  ~\makeLineNumberEven~
-\end{quote}
-The first is used in \emph{running} mode, the other two in
-\emph{pagewise} mode.  If you modify those, you cut into the
-margin selection mechanism as advertised above.  You will have to call
-a mode selection command after changing these macros, to make them take
-effect (at least for ~\makeLineNumberRunning~).  
-
-You can go up one more step.  The margin selection commands redefine
-the above macros by making them equivalent (~\let~) to one of the
-following macros
-\begin{quote}\obeylines
-  ~\makeLineNumberLeft~
-  ~\makeLineNumberRight~
-\end{quote}
-You may redefine these, and afterwards issue a margin selection
-command followed by a mode selection command.  The default definitions
-are
-\begin{quote}
-  ~\def\makeLineNumberLeft~\\
-  ~  {\hss\linenumberfont\LineNumber\hskip\linenumbersep}~
-\end{quote}
-and
-\begin{quote}
-  ~\def\makeLineNumberRight~\\
-  ~  {\linenumberfont\hskip\linenumbersep\hskip\textwidth~\\
-  ~    \hbox to\linenumberwidth{\hss\LineNumber}\hss}~
-\end{quote}
-Whatever you do, use ~\LineNumber~ to print the digits.  This ensures
-that the modulo mode setting is acknowledged.  If you want to
-customize that as well, this is the macro to change.  ~\LineNumber~
-eventually refers to ~\thelinenumber~, which is the place to customize
-the numerals themselves.  At the end of this paragraph I said
-\renewcommand\LineNumber{\ifodd\value{linenumber} \thelinenumber)\fi}
-\begin{quote}
-   ~\renewcommand\LineNumber~\\
-   ~   {\ifodd\value{linenumber} \thelinenumber)\fi}~
-\end{quote}
-Line number references are not affected by ~\LineNumber~, but you
-should keep track of ~\thelinenumber~.  Look at the following
-reference
-\begin{quote}
-  The setion title of the next section is on page \pageref{ll1}, line
-  \ref{ll1}.
-\end{quote}
-There is a mismatch in the definition of ~\thelinenumber~, from the
-point of the refered line to the reference here.
-\end{pagewiselinenumbers}
-
-\begin{pagewiselinenumbers}
-
-\section[Line number references]
-        {Line number references\linelabel{ll1}}
-
-\lineno.sty allows to refer to a line number with ~\ref{~<label>~}~.
-The label is set by ~\linelabel{~<label>~}~, anywhere in a paragraph
-that gets line numbers.  If you put a ~\linelabel~ somewhere else, the
-line number it refers to is pretty meaningless, but no error message
-is issued.  (This section begins on line \ref{ll1}, page
-\pageref{ll1} and ends on line \ref{ll2}, page \pageref{ll2}.)
-
-References work both in \emph{running} and \emph{pagewise} modes.
-However, you have to be very careful when using both \emph{real
-  pagewise} mode and \emph{running pagewise} mode: The mode setting
-must be the same during reference as during labeling.
-
-The restrictions on placing a ~\linelabel~ are the same as for a
-~\marginpar~.  (In fact, they are implemented as fake ~\marginpar~s.)
-E.g., the linelabel on the section header of this chapter could not be
-placed in the straight forward way, because it would cause an error in
-the table of contents.  (It should be disabled during \emph{toc}
-processing.)  Instead, I typed
-\begin{quote}
-  ~\section[Line number references]~\\
-  ~        {Line number references\linelabel{ll1}}~
-\end{quote}
-This works fine, with the standard \LaTeX\ ~{article}~ document
-style.  If more generic markup is required, you should avoid things
-like this (you should avoid \lineno.sty altogether, in that case).
-
-~\linelabel~ does not work in display math.  (Why,  you do not use
-equation numbers?)
-
-The ~\linelabel~ command starts a new paragraph if it is issued after
-an empty line.  It will properly ignore further whitespace before the
-first word of text. Thus you can easily get a label to the first line
-of a paragraph.  
-
-Furthermore, ~\linelabel~ uses \LaTeX s standart tricks to avoid
-unnecessary spaces if you place is between two words with spaces
-around, but you should not do that anyway, if you want to make sure
-that the label applies to a certain word in the text.  You should
-attach the line label to the word in question without intervening
-spaces, either before of after the word.  If you leave spaces both
-before and after the ~\linelabel~ command, the current implemenation
-attaches the line label to the following word (by ignoring the
-trailing space).
-
-Special care should be taken at the end of a paragraph.  You better
-put the line label without intervening spaces behind the period, like
-this 
-\begin{quote}
-  ~This is the end of this section.%~\\
-  ~\linelabel{ll2}~
-\end{quote}
-This is the end of this section.%
-\linelabel{ll2}

-\section{Known incompatibilities}
-
-This section will expand whenever somebody discovers problems when
-using \lineno.sty together with other \LaTeX\ packages.
-
-\subsection{\texttt{wrapfig.sty}}
-
-\lineno.sty used to have problems with \texttt{wrapfig.sty}, but this
-is solved but \lineno.sty, version 2.05.
-
-
-\section{Extension packages}
-
-The extension packages were abolished with version v3.00 of
-\lineno.sty.  One package, ~itemrule.sty~, was dropped, the others
-were put directly into the the main \lineno.sty package file.
-
-\subsection{Display math, \texttt{\itshape mlineno}}
-
-\lineno.sty does not work well with display math.  The parts of a
-paragraph preceeding a display math will not get line numbers.  The
-reason is that the paragraph is not finished, but the part above the
-display is broken into lines anyway.
-
-Let me demonstrate the effect.  This paragraph contains a
-~{displaymath}~ environment.  The part before the Formula does not get
-line numbers.  Here comes the Formula
-\begin{displaymath}
-    \mathrm{6\,H_2O + 6\,CO_2 \ \rightarrow\  C_6H_{12}O_6 + 6\,O_2}
-\end{displaymath}
-which makes the line numbers disappear.  The trailing part of the
-paragraph does get line numbers.  
-
-There are several means to solve the problem, but none of them is
-fully satisfactory.  \lineno.sty defines a ~{linenomath}~ environment,
-which can be wrapped around a display math to make the line numbering
-work.  This will work with any kind of display math, even if you use
-explicit ~$$~ pairs.  There is a ~*~-form ~{linenomath*}~ which also
-numbers the lines of the display itself, as good as it can.  Here
-comes an example use of ~{linenomath*}~
-\begin{linenomath*}
-\begin{eqnarray*}
-  b_1 &=& a_{11}x_1 + a_{12}x_2 \\
-  b_2 &=& a_{21}x_1 + a_{22}x_2   
-\end{eqnarray*}
-\end{linenomath*}
-wrapping an ~{egnarray*}~ like this
-\begin{quote}
-  ~\begin{linenomath*}~\\
-  ~  \begin{eqnarray*}~\\
-  ~    b_1 &=& a_{11}x_1 + a_{12}x_2 \\~\\
-  ~    b_2 &=& a_{21}x_1 + a_{22}x_2~\\   
-  ~  \end{eqnarray*}~\\
-  ~\end{linenomath*}~
-\end{quote}
-Specifying the package option ~[mathlines]~, causes the
-~{linenomath}~ environment to switch its function with its *-form.
-This allows you to later decide if you want the numbers on the formulas
-or not, without putting in stars everywhere (as long as you have been
-consistent).
-
-The ~{linenomath}~ wrapper does nothing if line numbering is not
-activated.  You do not need to remove them if you decide to omit the
-line numbering later (although you still have to load \lineno.sty).
-
-The \texttt{\itshape mlineno} extension redefines the standard \LaTeX\ 
-display math environments to wrap themselves automatically into
-~{linenomath}~:
-\begin{quote}\obeylines
-   ~\[~ ~\]~
-   ~{displaymath}~
-   ~{equation}~
-   ~{eqnarray}~
-   ~{eqnarray*}~
-\end{quote}
-As of version 3.00 you can activate this by the package option
-~[displaymath]~.  You can keep existing explicit ~{linenomath}~
-wrappers without harm.  
-
-This will probably not work with AMSmath.
-
-Other solutions to make \lineno.sty work with display math are either
-ugly or less stable.  The ugly possibility is to precede every display
-math with an empty line, or better with
-\begin{quote}
-  ~{\par\nobreak\noindent}~
-\end{quote}
-but this gains you nothing compared to using the ~{linenomath}~
-environment, since you still have to modify your document.
-
-\end{linenumbers*}
-
-
-\subsection{\texttt{\itshape rlineno}}
-
-\begin{runninglinenumbers}
-It is currently not possible to put a ~\linelabel~ into math mode.
-This should not impose problems with inline math, since you can attach
-the label just outside the math shift, like\linelabel{rll1} 
-\begin{quote}
-  ~... \linelabel{~<label>~}$x=f(y)$ ...~
-\end{quote}
-but to refer to a line in display math, you cannot label it directly. 
-\end{runninglinenumbers}
-
-\begin{pagewiselinenumbers}
-The extension \texttt{\itshape rlineno} offers a solution,
-allowing to refer to a line number with an offset.  
-
-This extension is now available with plain \lineno.sty v3.00.
-
-You put the ~\linelabel~ at the end of the preceeding line, and refer
-to that number, plus 1 or, in case of multiline displays, by any other
-offset.\linelabel{rll2}
-\begin{quote}
-  ~...\linelabel{~<label>~}~ \\
-  ~\begin{equation}~ \\
-  ~     y=f'(x)~ \\
-  ~\end{equation}~ \\
-  ~... the formula in line \lineref[+1]{~<label>~}~ 
-\end{quote}
-The offset calculation is different for pagewise or running line
-numbers, and you will have to make sure the right method is used. 
-\end{pagewiselinenumbers}
-
-The macro ~\lineref[~<offset>~]{~<label>~}~ uses the method of the
-currently selected mode (line numbering need not be activated).  To
-specify the mode explicitly, use ~\linerefr~ or ~\linerefp~ for
-running or pagewise mode respectively.
-
-For example, the manual sets a ~\linelabel{rll1}~ at the end of the
-line preceeding the single line quote environment at
-line\,\linerefr[+1]{rll1} in the first paragraph of this chapter, and
-refered to it via
-\begin{quote}
-  ~\linerefr[+1]{rll1}~
-\end{quote}
-and another one preceeding the quote environment in the second
-paragraph of this chapter, with the central line
-numbered\,\linerefp[+3]{rll2}, which I just refered to via
-\begin{quote}
-  ~\linerefp[+3]{rll2}~
-\end{quote}
-\begin{runninglinenumbers}
-If the correct mode is selected (e.g., ~\setrunninglinenumbers~),
-you can use ~\lineref[+1]{rll1}~ to refer to
-line\,\lineref[+1]{rll1}.

-\subsection{\texttt{\itshape numquote}}
-
-This extension defines two environments, each of them with a *-form or
-alternatively an optional argument.
-\begin{quote}\obeylines
-  ~\begin{numquote}~
-  ~\end{numquote}~
-\end{quote}
-is like ~{quote}~,
-\begin{quote}\obeylines
-  ~\begin{numquotation}~
-  ~\end{numquotation}~
-\end{quote}
-is like ~{quotation}~, but with the lines numbered.  Numbering
-restarts with 1 each time it is used, except you use the *-form, or
-specify the line number to start with in an optional argument.
-\begin{numquote}
-The line numbers set to the left of the text, indented by the same
-amount as the quote or quotation.  This works as expected even if the
-quote appears in a nested list. 
-\end{numquote}
-To customize the distance from the text or the shape of the
-numbers, you can modify the macros ~\quotelinenumbersep~ and
-~\quotelinenumberfont~ respectively.
-
-As of version 3.00, this is available directly with \lineno.sty.

-\subsection{\texttt{\itshape ilineno}}
-\label{sec:ilineno}

-\begin{center}
-\noindent\fbox{\parbox{0.8\textwidth}{
-  \internallinenumbers \resetlinenumber[13]
-  Sometimes you need line numbers within a |\parbox\ or figure.  This
-  extension can do that, if the text is simple enough.  It works by
-  drawing a ladder of numbers next to the paragraph, each number
-  vertically separated by |\baselineskip\ from the other.  This
-  obviously dose not work nicely with anything but straight text.
-  Extra high lines (like this: $\displaystyle x=\frac AB$) will
-  disturb the alignment.  The power of \lineno.sty is not necessary to
-  achieve this, but you may need both in one document with a somewhat
-  coherent interface, and some of the necessary infrastructure from
-  \lineno.sty is actually useful.
-}}\end{center}
-% Why is the v-spacing wrong here?
-
-The preceding paragraph was set like this:
-\begin{quote}
-  ~\begin{center}\fbox{\parbox{0.8\textwidth}{~ \\
-    ~\internallinenumbers~ \\
-    ~\resetlinenumber[13]~ \\
-    ~ ~ Sometimes you need \dots \\
-  ~}}\end{center}~
-\end{quote}

-\subsection{\texttt{\itshape itemrule.sty}}
-
-Somebody asked me if he can get a rule next to an itemized item, from
-the bullet downwards.  This style did that.  It was unstable and of
-little interest, so it is gone from the \lineno.sty distribution.
-
-\subsection{\texttt{\itshape bframe}}
-\label{sec:bframe}
-
-\setlength\bframesep{10pt}
-\begin{bframe}
-\lineno.sty can be used for unexpected purposes.  The environment 
-\begin{quote}\obeylines
-  ~\begin{bframe}~
-  ~\end{bframe}~
-\end{quote}
-draws boxes around some text, even across page breaks.  At a page
-break, the box is open (it is difficult to fix that).  There are two
-parameters:
-\begin{description}\itemsep=0pt\parskip=0pt
-\item [|\bframesep] \leavevmode\\
-  defines the separation of the box from the text.
-\item [|\bframerule] \leavevmode\\
-  defines the thickness of the lines around the text.
-\end{description}
-
-It works by asking \lineno.sty to draw small rules left and right to
-the lines.  The total height of the rules is ~\baselineskip~ plus
-~\bframesep~. This leaves some extra space for extra high lines.
-
-The current version is very preliminary.  In a future version there
-may be a possibility to move the vertical lines inwards for indented
-text.  The box may optionally be closed at page breaks.  It will not
-likely be possible to have a colored background in the box, at least
-not with a graphics driver that cannot put a background behind
-existing foreground (Postscript cannot, I've been told).  Tell me how
-to make a gray background, like block dots on transparent, and I can
-do shaded boxes.

-\end{bframe}

-\section{How to print the documented source}
-
-\begin{bframe}
-\lineno.sty is written in three programming languages: \TeX, sh,
-and awk.
-
-The file can be loaded as a \LaTeXe\ package as it is.  However, if
-you feed it into a Unix shell, like
-\begin{quote}
-   ~csh>  source ./lineno.sty~
-\end{quote}
-it will produce the files ~lineno.tex~ and ~lineno.dvi~, which is the
-documented source of \lineno.sty.  If you want to learn how it works,
-or you need to adapt \lineno.sty for some special requirements, you
-should read that document.
