+% While version v0.1 of 'ednotes' 
+% just aimed at not loosing annotations to footnotes
+% and v0.2 aimed at printing annotations to main text 
+% earlier than annotations to footnotes, 
+% v0.3 aims at starting an annotation to a footnote 
+% on the same page where the annotated passages starts. 
+% %% 2011/01/19:
+% v0.4 introduced `\clearfootnoteannotations'.
+% v0.5 fixes a basic mistake from v0.2 and aims at 
+% more transparent code, including a re-implementation 
+% of 'ednotes'' core macro.
+% v0.6 re-implements v0.2 in the sense that, when 
+% lemmas move among pages, the annotations needn't wander 
+% to the end of the edition as often as with v0.2 through v0.5.
+'ednotes.sty' has addressed ``scholarly" critical editions 
+of (hand-written) manuscripts. 
+%% 2011/02/10:
+'edfnotes' additionally supports critical editions of 
+(printed) \emph{works with footnotes.}
+The package was developed for an edition of 
+\Wikienref{Bernard Bolzano}'s 
+\textit{Paradoxien des Unendlichen} by Prof.\ Dr.\ Dr.\ Christian 
+Tapp---a work with some very long footnotes. 
+
+%% moved etc. 2011/02/14:
+As to \emph{implementation}, certain core parts 
+of 'ednotes' have been re-implemented entirely, this may 
+later migrate into 'ednotes' itself.
+It had been hoped that 'edfnotes' could build on the 
+\ctanpkgref{bigfoot} package.\urlfoot{CtanPkgRef}{bigfoot}
+This might have improved (automatic) page breaking and placement 
+of original footnotes and critical annotations 
+(whereas at present, some page breaks need manual trial-and-error 
+ solutions). 
+However, analysis of 'lineno' and 'ednotes' for extending them,
+as well as many unexpected difficulties,
+exhausted project resources too early.
+David Kastrup's `\MakeSorted' 
+(or `\MakeSortedPerPage', actually from 
+ \ctanpkgref{perpage})\urlpkgfoot{perpage} 
+has here been implemented 
+by `\insert'ing annotations to footnotes at the last main text line of 
+a page only, hooking into 'lineno''s numbering mechanism---a 
+nice (``leight-weight"---?) alternative to David Kastrup's approach.

+%% by Prof.~Dr.\ Dr.\ Christian Tapp 
+%% at Ruhr-Universit\"at Bochum, Germany.}
+%% %% 2011/01/14:
+%% Christian also participated immensely in development 
+%% by creating really small failure examples for debugging.
+%% %% 2011/01/17:
+%% Completing the work was possible thanks to a loan 
+%% from my mother, Mrs.~Renate L\"uck.
+%% 
+%% === Known Issues ===
+%% Please note the following difficulties you may experience 
+%% with 'edfnotes', and what to do about them:
+%% \begin{enumerate}
+%%   \item  In certain situations, ``\strong{hanging}" of the `latex' 
+%%          run has been observed. 
+%%          As to \emph{implementation},            %% 2011/02/14
+%%          it has not been analysed completely yet (TODO), 
+%%          but it occurred with `\marginpar' and printing the second 
+%%          part of a footnote before its first part---a well-known 
+%%          \LaTeX\ bug, 
+%%          ``\strong{footnote placement disaster}." 
+%%          However, this situation usually does not 
+%%          lead into ``hanging," rather replacing `=' by \verb+>+
+%%          in the definition of `\EFN@annot' with package version 
+%%          v0.6 (to keep ``displaced" annotations from wandering 
+%%          to the last page) seems to cause the hang when a 
+%%          ``footnote placement disaster" occurs 
+%%          (where the footnote has annotations).
+%%
+%%          \strong{You must be careful with marginals anyway}---with 
+%%          critical editions. There also is the problem with 
+%%          placement in the wrong margin. Mistakes of the named kinds 
+%%          occur rather \emph{usually} in critical editions. 
+%%          With \emph{annotations to footnotes} things may become 
+%%          even worse, since placement restrictions 
+%%          (``start note on same page as target")
+%%          may become difficult or impossible to 
+%%          satisfy.\footnote{These advices should appear in 
+%%              'ednotes' already---TODO!}%% 2011/02/10
+%%
+%%          Often, just manual `\pagebreak's (in the last line of a 
+%%           page---when near completion of the work) help.
+%%
+%%          The \ctanpkgref{mparhack} package\urlpkgfoot{mparhack} at least 
+%%          ensures that marginals appear in the appropriate margin.
+%%
+%%          ``Footnote placement disasters" can be avoided (at some cost) 
+%%          by the \ctanpkgref{tamefloats} package\urlpkgfoot{tamefloats}
+%%          (helped sometimes, did not help with 
+%%          \textit{Paradoxien des Unendlichen}). 
+%%          Another possibility for avoiding footnote placement disasters 
+%%          due to `\marginpar' is using `\marginnote' from the 
+%%          \ctanpkgref{marginnote} package\urlpkgfoot{marginnote}
+%%          instead.
+%%
+%%          However, `\marginnote' behaves badly when, e.g., page breaks 
+%%          in two sources appear in the same line of the edition.
+%%          On the other hand, `\marginpar' ``moves" the second marginal, 
+%%          which is not much better. I would prefer a ``manual" 
+%%          solution: inserting the page break symbols within the 
+%%          line manually and produce a single `\marginpar' or 
+%%          `\marginnote' entry for both of them.
+%%          (Actually, this could be automated within 'lineno'.)
+%%
+%%   \item  \strong{Page break oscillations:} \
+%%          'ednotes.sty' provides a message about page break 
+%%          oscillations that gives advice how to fix them. 
+%%          With annotations to footnotes, that advice may help only 
+%%          little. Besides fixing the page break in main text, 
+%%          it may be needed to place `\pagebreak' 
+%%          (or `\warningpagebreak') commands in footnotes too. 
+%%          While the oscillation of main text lines is fixed 
+%%          (for the page about the message reports),
+%%          page breaks of footnotes may keep oscillating. 
+%%          I was successful in a test case 
+%%          (that giant footnote in \textit{Paradoxien des Unendlichen}) 
+%%          by placing a `\pagebreak' in the footnote text quite 
+%%          early first and then moved it down line by line, 
+%%          until the result became bad. At that point, I chose 
+%%          the previous position of `\pagebreak'.
+%%          The result is presented as `PdUsample.pdf'. 
+%%          % (part of documentation, `docint/' directory). %% rm. 2011/02/16
+%%
+%%   \item  For \strong{other Limitations}, please see the section 
+%%          in 'fnlineno.pdf' of this title.
+%% \end{enumerate}
+%%
+%% === Installing and Calling ===
+%% The file 'edfnotes.sty' is provided ready, installation only requires 
+%% putting it somewhere where \TeX\ finds it 
+%% (which may need updating the filename data 
+%%  base).\footnote{\url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=inst-wlcf}}
+%% 
+%% As usually, 'edfnotes.sty' is loaded by 
+%% % \begin{verbatim}
+%%     `\usepackage{edfnotes}'
+%% % \end{verbatim}
+%% below the `\documentclass' line          %% 2011/01/13
+%% (after loading 'ednotes') 
+%% and before `\begin{document}'.
+%% 'edfnotes' does not offer any package options.
+%% 
+%% This should suffice just to get the advertised functionality. 
+%% There are \emph{two} user commands |\ForceFootnoteAnnotations|
+%% and |\clearfootnoteannotations|
+%% described in section~\ref{sec:enddoc}.
+%% 
+%% %% 2011/02/16:
+%% Minimum functionality of 'edfnotes' requires that 
+%% \CtanPkgRef{ednotes}{ednotes.sty}, 
+%% \CtanPkgRef{lineno}{fnlineno.sty}, and
+%% \CtanPkgRef{lineno}{lineno.sty} are installed and ``visible."
+%% For more functionality, see the descriptions of both 
+%% bundles.\urlpkgfoot{ednotes}\urlpkgfoot{lineno}.

+%%
+%%   \pagebreak                             %% 2011/02/16
+%%  == Implementation ==
+%% === Loading Required Package           ===
+%% The package builds on 'fnlineno''s ability to 
+%% number footnote lines and processing `\linelabel' there. 
+%% So we load it. %%% (TODO or `\AtBeginDocument'?):
+%% We need a version without earlier tries at supporting 
+%% 'edfnotes.sty' v0.2:
+\RequirePackage{fnlineno}[2011/01/07]
+%%
+%% === Overview of Processing Levels      ===
+%% %% new 2011/01/18
+%% 'ednotes'' and 'edfnotes'' apparatus entries 
+%% are handled by the 'manyfoot' package. 
+%% An entry <insert> for apparatus level <note-fam> 
+%% is passed to 'manyfoot' by 'manyfoot''s command 
+%% |\Footnotetext<note-fam>\@empty{<insert>}|. 
+%% 
+%% In terms of \TeX's hard-wired mechanisms, 
+%% such a `\Foonotetext' command issues an `\insert'
+%% command. `\insert' is a so-called ``primitive," 
+%% hard-wired command. It typesets the entry <insert> 
+%% and stores the result internally, and in choosing 
+%% the next page break, \TeX\ will try to start 
+%% the typesetting result of <insert> on the ``current" page. 
+%% 
+%% \TeX\ is not so well-prepared (\strong{hard-wired}) 
+%% for placing a footnote <ff> (its beginning) 
+%% intended to refer to a passage 
+%% in another footnote <f> on the same page as that passage 
+%% (starts). 
+%% Our \strong{hard-weird} macros build an own mechanism 
+%% using the `.aux' file in order to manage this. 
+%% A footnote <ff> to a footnote <f> is not directly passed to 
+%% 'manyfoot', such ``secondary" footnotes <ff> are rather 
+%% withhold and collected in a list <list> from which 
+%% 'edfnotes' will later decide what to do with them. 
+%% The goal is to find a good point for finally passing 
+%% <ff> to 'manyfoot' such that \TeX\ will be able to place 
+%% <f> and <ff> appropriately. 
+%%
+%% In the most basic application of 'edfnotes', 
+%% there is \emph{one} critical apparatus referring both 
+%% to the main text and to the footnotes of an edited text. 
+%% We want that, in the apparatus, 
+%% annotations to \emph{main text} lines 
+%% precede annotations to \emph{footnote} lines.
+%% To achieve this, the idea is to issue the 
+%% `\Footnotetext' commands for annotations to footnotes 
+%% only at \emph{last main text lines} of pages. 
+%% 
+%% Unfortunately, sometimes the `.aux' file provides 
+%% either \emph{no} or \emph{wrong} information for 
+%% identifying that last line. Therefore, we sometimes 
+%% \emph{skip} the item-by-item procedure that tries to pair 
+%% <ff> with <f>, and instead somewhere pass \emph{all} the 
+%% <ff> items in that list <list> to 'manyfoot' 
+%% and \TeX's primitive `\insert' command. 
+%% This will be just a kind of ``emergency" routine, 
+%% considered necessary temporarily, while hoping that 
+%% the required and correct information will appear 
+%% in the `.aux' file some runs later. 
+%% 
+%%   \pagebreak                             %% 2011/02/16
+%% === Postponing Annotations             ===
+%% ==== Goal and Strategy ====
+%% Version v0.2 of 'edfnotes' used 
+%% `\@EN@hookfn{<insert>}'---that is called from 'ednotes'' 
+%% `\@EN@putdown'---in order to intercept %%% and collect 
+%% 'manyfoot''s `\FootnotetextA' etc. commands that 
+%% execute \TeX's `\insert' commands for 'ednotes'' annotations. 
+%% `\@EN@hookfn' has the trivial meaning `\@firstofone' in 'ednotes'
+%% and is only activated by 'edtable.sty' ('lineno' bundle)
+%% in order to collect annotations to a tabular environment 
+%% at the latter's ``footnote hook" that finally executes 
+%% the `\insert' commands. These annotations 
+%% are inserted to the \emph{current} page, i.e., 
+%% all the annotations collected there 
+%% start on the same page. 
+%% 
+%% This behaviour (starting on the same page) 
+%% is in general not adequate with annotations to footnotes 
+%% when the latter are split and continued at later pages. 
+%% If a footnote starts at page~$p$, is continued on 
+%% page~$p+1$, and a passage of it on page~$p+1$ gets a 
+%% critical annotation, that annotation should start on 
+%% page~$p+1$, not on page~$p$. The footnote may also get 
+%% an annotation to its page~$p$ part, that one should start 
+%% at page $p$ indeed. The mechanism we have to introduce here
+%% must be able to tell these two cases apart. 
+%% For each annotation to a footnote, it must retrieve the 
+%% page which the annotation refers to. 
+%%
+%% Interception at 'ednotes'' `\@EN@hookfn' now becomes too clumsy. 
+%% We redefine 
+%% \[|\@EN@putdown{<id>}{<note-fam>}{<lemma-tag>}{<note>}|\]
+%% entirely, replacing its former `\@EN@hookfn' section 
+%% by a new macro

+%%
+%% === Inserting Annotations to Footnotes ===
+%% ==== Strategy ====
+%% Version v0.2 of 'edfnotes.sty' aims at proper \strong{sorting} 
+%% of the annotations, in the sense that in the critical apparatus, 
+%% notes on \emph{main text} lines appear before all notes 
+%% to \emph{footnote} lines. 
+%%
+%% David Kastrup's 'bigfoot' and 'perpage' packages 
+%% seem to deal with this task 
+%% (however, the documentation doesn't help much in 
+%%  making use of it); on the other hand,
+%% 'lineno.sty' offers its own nice tools ... 
+%%
+%% Our idea is inserting all the \emph{annotations to footnotes}
+%% right after the \emph{last main text line of the page}---this 
+%% way they should appear \emph{after} all annotations to main text lines. 
+%% (This idea grew with v0.2, and with v0.3 it became clear 
+%%  this hook can be used for passing certain annotations 
+%%  to the next page.)
+%% % ; `samepage@hook' then turned into `annot@hook'.) 
+%% %% <- indeed 2011/01/17
+%% 
+%% For version v0.3, this is refined a little. 
+%% The hook will not actually `\insert' all annotations, 
+%% it will rather choose some for immediate insertion 
+%% and collect the remaining annotations 
+%% in the hook for the next page.
+%% 
+%% We use |\MakeLineNo| from 'lineno.sty' for hooking in here 
+%% (you may find the context relevant here in `fnlineno.pdf'). 
+%% `\MakeLineNo'---in ``pagewise" mode 
+%% that we assume here---has access to the absolute number 
+%% of the last numbered line of the current page, 
+%% involving 'lineno.sty''s |\testLastNumberedPage|. 
+%% We modify the latter so that it records that number as 
+%% |\theLastLineNumber|. 
+%% % (I tried more efficient things 
+%% %  involving a switch, failed terribly, 
+%% %  no idea what was going on.) %% 2011/01/07
+%% ==== Deciding ====
+%% |\EFN@run@annot@hook| first expands `\EFN@annot@hook', 
+%% then empties it, 
+%% and while the version for the recent page runs, 
+%% the version of |\EFN@annot@hook| for the \emph{next} page 
+%% may be built, containing annotations to footnote passages 
+%% on later pages:
+\def \EFN@run@annot@hook {%
+    \expandafter \global \expandafter \let
+        \expandafter \EFN@annot@hook \expandafter \@empty
+    \EFN@annot@hook}
+%% |\EFN@annot@hook| (unless empty) is a list of commands 
+%% \[|\EFN@annot{<id>}{<note-fam>}{<lemma-tag>}{<note>}|\]
+%% that were issued either by `\@EN@putdown' or by the previous
+%% version of `\EFN@run@annot@hook' using `\EFN@move'.
+%% `\EFN@annot' uses <id> to determine the page number where 
+%% the footnote passage the annotation refers to starts.
+%% There are \emph{three} cases deciding about immediate `\insert'ion 
+%% vs.\ postponing. The annotation is `\insert'ed immediately 
+%% if \emph{either} <id> has not been used in the previous run 
+%% (it contains an annotation number exceeding the earlier 
+%%  number of annotations---minus one) \emph{or}
+%% if the annotation was placed on the ``current" page 
+%% in the run before. In these cases, the four arguments of 
+%% `\EFN@annot' are run by |\EFN@@appentry|. \emph{Otherwise} 
+%% the annotation is deferred by running the four arguments 
+%% with |\EFN@move|.
+\def \EFN@annot #1{%
+  \let \EFN@next \EFN@@appentry
+%% I.e., immediate `\insert'ion is the ``default." 
+%% `undefined' in the next line means there is no placement 
+%% information from the previous run 
+%% (stored as `\r@<id>'). If there is, it is

+%% ==== Normal Insertion          ====
+%% The ``normal" way of inserting annotations to footnotes 
+%% is a call from the extended `\MakeLineNo' 
+%% involving testing whether the line is the last 
+%% numbered one on the page. It seems not to have been 
+%% easily accessible with 'lineno.sty', we are extending 
+%% the latter's |\testLastNumberedPage| so it stores
+%% that number as |\theLastLineNumber|. 
+%% Indeed, calculating the ``pagewise" line number 
+%% in `\MakeLineNo' invokes a series of tests 
+%% that finally calls \[`\testLastNumberedPage{<int>}'\]
+%% where <int> is the least ``last" line number of a 
+%% page with numbered lines that is greater than or

+%% \paragraph{2.} Another problem may occur with the

+%% When between two \LaTeX\ runs the number of 
+%% main text lines is reduced (e.g., one has removed 
+%%  wrong text or has improved line breaking by a manual 
+%%  change of hyphenation), the annotations for the last 
+%% page may get lost because the line number that the 
+%% insertions wait for doesn't occur any more. They will 
+%% then get lost, and their `\newlabel' entries in the
+%% `.aux' file will be missing, perhaps resulting in 
+%% other errors. We provide a command 
+%% |\ForceFootnoteAnnotations| for manual use by authors 
+%% or for being added to certain hooks. It might be 
+%% added to `\nolinenumbers' and `\endlinenumbers', 
+%% but I am not sure ...

+%% \strong{chapter ends} with a very 
+%% \strong{long footnote} with annotations 
+%% to all of its pages, and the editor decides 
+%% that the footnotes should fill the final pages 
+%% of the chapter without main text on their pages. 
+%% Then the annotations have problem with our 
+%% approach of v0.3. 
+%% %
+%% A similar problem could be that a short end 
+%% of the last footnote of a chapter 
+%% gets remarks of several pages that the editor 
+%% doesn't want to see in the following chapter 
+%% (e.g., when there isn't any following chapter).
+%%
+%% We therefore provide a command 
+%% |\clearfootnoteannotations|
+%% that creates dummy page entries for those final pages. 
+%% Of course, these dummy page entries must not be 
+%% numbered like lines ...
+%% 
+%% The first version of the macro worked fine with a
+%% two-page footnote, but crashed as soon as a main text line
+%% was removed. (Infinitly many pages are created then ...\,) \
+%% This is just the problem that was addressed by
+%% |\ForceFootnoteAnnotations|. But it would be very wrong to use 
+%% `\ForceFootnoteAnnotations' for the present problem,

+%% ==== &\newlabel\ Building Info Macros ====
+%% %% 2011/01/10:
+%% For version v0.3 of 'edfnotes', it turns out that 
+%% 'ednotes'' (v1.1--1.3) mechanism for building the 
+%% note info macros `\r@EN@l<id>' assumes that 
+%% \[`\newlabel{-EN@l<id>}{<start-lemma-place>}'\] 
+%% will appear before
+%% \[`\newlabel{+EN@l<id>}{<end-lemma-place>}'\]
+%% and
+%% \[`\newlabel{EN@l<id>}{<note-place>}'\] 
+%% in the `.aux' file. 
+%% With 'edfnotes' v0.3, an annotation to the second page 
+%% of a long footnote will be `\insert'ed on the previous 
+%% page in a ``first" run (no `.aux' present) due to the 
+%% missing placement information. 
+%% 'ednotes'' `\newlabel' mechanism then looses the 
+%% note placement information, and a ``missing number" 
+%% error occurs.
+%%
+%% To fix this, we modify 'ednotes'' 
+%% |\@EN@addtolabeldef| so that at the first step of 
+%% the recursive building of `\r@EN@l<number>', 
+%% the latter is not used as input (as a part).
+%% Then the tricky `\@gobble' in the first case of 'ednotes'' 
+%% redefinition of |\newlabel| (see the recent presentation 
+%%  of the code---currently [2011/01/10] `ednotesc.pdf') 
+%% can be replaced by the obvious empty argument.
