+% 
+% *Overview:* 
+% This package provides facilities for notes in (critical) editions. 
+% `\Anote{LEMMA}{NOTE}' prints NOTE in an extra footnote apparatus, 
+% referring to LEMMA by its line numbers (as generated by 
+% `lineno.sty') and by repeating LEMMA in the note. By calling the 
+% package with extra options, you can add \Bnote etc. and choose 
+% whether notes of one apparatus appear in a single paragraph on 
+% each page or in separate paragraphs (`manyfoot.sty'). 
+% In LEMMA, `...\<...\>...' indicates what short version of it is to 
+% appear in the note. There are further facilities to customize 
+% appearance of notes. 
+% Commands \Anotelabel{LABEL}, \donote{LABEL}{NOTE} etc. vary \Anote 
+% etc. in admitting overlapping lemmas. 
+% ---The package is made for those who need something like EDMAC 
+% but who want to employ LaTeX2e at the same time. 
+% More detailed description below is divided into 
+% `packages required', `user commands', `package options', 
+% `customizing', `Note on EDMAC', and `Comparison with LEDMAC'. 
+% 
+% *Note on "rival" package LEDMAC:* Peter R. Wilson has made a 
+% LaTeX package LEDMAC (available on CTAN) for about the same 
+% purpose as the present package. See `Note on EDMAC' and 
+% `Comparison with LEDMAC' below. 
+% 
+% *Printed presentation:* An article on `ednotes' with user 
+% instructions, examples, and comparisons with `[L]EDMAC' 
+% appeared in the TUGboat volume for 2003. A version of it is 
+% obtainable from the `ednotes' CTAN folder (`ednotugb.pdf'). 
+% 
+% *Packages required:* 
+% This package will not work without the following ones 
+% ("visible"--cf. visible.txt in CTAN ednotes folder): 
+% o  Packages `manyfoot.sty' and `nccfoots.sty' by 
+%    Alexander I. Rozhenko from the `ncctools' bundle. 
+%    You needn't know anything about these 
+%    except perhaps options `para' and `para*' 
+%    choosing footnote indentation (see `package options' below). 
+% o  Package `lineno.sty' by Stephan I. B"ottcher. 
+%    We here suppose that you know and employ some of the 
+%    line numbering commands from `lineno.sty'. 
+% However, please don't load these packages on your own. 
+% Instead of calling them with some options, put these options 
+% into the brackets of \usepackage[<options>]{ednotes}. 
+% 
+% *Availability:* 
+% o  In case you have not received `manyfoot.sty' and `nccfoots.sty', 
+%    you find them in the CTAN folder 
+%      `macros/latex/contrib/ncctools/unpacked' . 
+%    You find PDF documentations in 
+%      `macros/latex/contrib/ncctools/doc' . 
+% o  `lineno.sty' is in CTAN folder `macros/latex/contrib/lineno'. 
+%    In the same folder, there is `lineno.pdf' for documentation. 
+% 
+% *Optional packages:* 
+% o  Some package options may need additional package files (for 
+%    a while). They may be in the `ednotes' or `lineno' CTAN folder.
+%    The README files there will name them or tell where they are 
+%    named.                                                            %% TODO
+% 
+% *Other useful files:* 
+% Look at the README file in CTAN folder 
+% `macros/latex/contrib/ednotes' for quick information on what other 
+% files in the folder provide.                                %% TODO: indeed? 
+% 
+% *User commands:* 
+% *Basic:* --------------------------------------------------------
+% \Anote{LEMMA}{NOTE} prints LEMMA where it occurs 
+% and sends NOTE into an extra footnote apparatus. 
+% The lines where the command occurs must be numbered 
+% by using commands from package `lineno.sty'. 
+% In the footnote, NOTE is preceded by line numbers of LEMMA, 
+% by a version of LEMMA (see below), and by some separating stuff. 
+% Separating stuff by default is a properly spaced right bracket 
+% according to \lemmafmt (see below). 
+% \Anote may be nested in LEMMA. 
+% (Overlapping lemmas may be generated by \Anotelabel etc. as 
+% described below.)
+% For customizing appearance of notes, see `package options' and 
+% `customizing' (\lemmafmt and \lemmaellipsis, e.g.) below. 
+% For additional analogous commands \Bnote etc., see 
+% `"optional" user commands' below. 
+% *Short lemma substitute in note:* -------------------------------
+% (The following describes a comfortable extension of 
+% EDMAC's \lemma.)
+% LEMMA argument of \Anote as above may appear as `L1\<L2\>L3', then 
+% only L1 and L3 appear in the footnote with some ellipsis symbols 
+% between them. By default, these are \textsymmdots according to 
+% \lemmaellipsis. 
+% (For \textsymmdots vs. ordinary \dots see `miscellaneous' below.) 
+% L2, however, may start with `<ELL>', then ELL is used instead of 
+% \textsymmdots or whatever else \lemmaellipsis might call. 
+% (To be sure, symbols `\<', `<', `>', `\>' work in a special way 
+% in LEMMA. `>' might be used inside ELL if inside braces, e.g., 
+% `\<<{$>$}>'. <ELL> works as an optional argument of \< like 
+% brackets usually do in LaTeX---we thought you might use `[' here 
+% as a symbol to be printed in main text. Care for proper spacing in 
+% both versions of the lemma by spaces touching \<, \>, and braces. 
+% ---A special version of the package would be necessary for those 
+% having no `<', `>' on their keyboards.) 
+% *Overlapping lemmas:* -------------------------------------------
+% \Anotelabel{LABEL}LEMMA\donote{LABEL}{NOTE} 
+% works just like \Anote{LEMMA}{NOTE} above. However, by using 
+% proper LABELs, you can indicate which of overlapping lemmas 
+% begins and ends where. Note that the second command is only 
+% \donote, not \Adonote. In LEMMA, \pause{LABEL} and \resume{LABEL} 
+% act analogously to \< and \> above for lemma substitutes, and 
+% \pause{LABEL}<ELL> employs your own ELL for the ellipsis. 
+% LEMMA may contain \Anote and the other way round (in some way). 
+% However, \pause{LABEL} must not be hidden in braces etc. 
+% *Commands in lemma as repeated in a note:* ----------------------
+% Some commands should work in main text, but not in the lemma 
+% text of the note, e.g. \label. With respect to some of them, 
+% `ednotes.sty' makes an adjustment for this. Nesting of lemmas, 
+% e.g., is enabled this way. 
+% For other commands, you can hide code from a note 
+% by \notinnote, e.g.: \notinnote{\footnote{...}}. 
+% If you know about relevant (La)TeX internals, you can define 
+% behaviour of commands in lemmas using \addlemmaexpands, e.g. 
+% \addlemmaexpands{\let\footnote\@gobble}. 
+% (However, the latter code is bad if \footnote should occur 
+% with an optional argument. Moreover, in some cases 
+% \let...\notinnote may handle spaces better than 
+% \let...\@gobble, since \notinnote uses a variant of LaTeX's 
+% \@bsphack and \@esphack. 
+% ---\addlemmaexpands has only local effect inside group.) 
+% \showlemmaexpands displays all these extra definitions 
+% which would apply in the lemma ahead. 
+% (A lot of commands might be changed here, we chose only few. 
+% Cf. EDMAC's \no@expands; EDMAC, however, deals with the 
+% problem in a different way and needs more changes 
+% than we do.)
+% *"Optional" user commands:* -------------------------------------
+% Each of \Bnote, \Bnotelabel, \Cnote, \Cnotelabel, \Dnote, 
+% \Dnotelabel, \Enote, and \Enotelabel is defined by calling 
+% respective package options `Bpara' or `Bplain' etc., see 
+% `package options' below. They work like \Anote and \Anotelabel, 
+% respectively, and nesting and overlapping of their lemmas works 
+% as for \Anote and \Anotelabel. \donote works with each of 
+% \Anotelabel, \Bnotelabel etc.---care for different labels. 
+% \nopunct may help you in case of certain changes of \notefmt, see 
+% `customizing' below (not active outside notes). 
+% *Miscellaneous:* ------------------------------------------------
+% As a byproduct, we provide \textsymmdots as an alternative to 
+% \dots or (more specific) to LaTeX2e's \textellipsis. We feel that, 
+% in the middle of the short version of a lemma, the text dropped 
+% should be replaced by symmetrically spaced dots, i.e., in 
+% L1 ... L3, the space between L1 and the dots should be the same 
+% as the space between the dots and L3. \textellipsis obstructs this 
+% by calling a space after the final dot which is not balanced by a 
+% space before the first dot. \textsymmdots just closes without that 
+% final space---that's all the difference to \textellipsis. (Cf. 
+% TeXbook p. 73 where $\ldots$ is recommended for the same purpose.) 
+% Of course, it is now your job to care for proper spacing on left 
+% and right, e.g., use it this \textsymmdots\ way. 
+% Note that with a comma following \dots is quite right while 
+% `\textsymmdots,' is bad. %% TODO: delimiters!? e.g. [...] 
+% -- Now (since Sep 2004) indeed there is the `ellipsis' package 
+% by Peter J. Heslin on CTAN in the /macros/latex/contrib directory! 
+% It deals with this problem much more thoroughly. 
+% *Wrong placement:* ----------------------------------------------
+% We do not provide helpful error messages for badly placed \<, 
+% \pause, and the like in this version. You will just get 
+% `undefined' errors, complaints about \mskip, or `runaway 
+% argument' errors.---Doubling labels with \Anotelabel etc. may 
+% work well if you know what you are doing. 
+% 
+% *Package options:* 
+% 1.) Options `left', `right', `switch', `switch*', `columnwise', 
+% `pagewise', `running', `modulo', `mathlines', `displaymath', 
+% `edtable' (edit tabular environments), `longtable' (edit 
+% `longtable' environments), `nolongtablepatch' are passed to 
+% package `lineno'; cf. the latter package for information 
+% (not yet tested all).                                                %% TODO 
+% `left' and `running' act by default. 
+% Option `mathnotes' calls `lineno.sty' package option `mathrefs', 
+% see `lineno' documentation as well. 
+% 2.) Option `Aplain' arranges all notes for one page generated 
+% by \Anote and \Anotelabel in a single footnote paragraph. 
+% Option `Bplain' generates an apparatus using one footnote 
+% paragraph for each note, with commands \Bnote, and \Bnotelabel. 
+% Option `Bpara' does the same but arranging all notes 
+% for one page in a single footnote paragraph. 
+% Analogues apply to `Cplain', `Cpara', `Dplain', `Dpara', 
+% `Eplain', and `Epara'. (There is `Apara' as well---default.)
+% Option `para*' suppresses indentation of footnote paragraphs 
+% coming from options like `Apara' (cf. package `manyfoot'). 
+%% TODO: para indent correct? 
+% 3.) Option `edmacpara' makes up for problems with `para' 
+% footnotes that are discussed in `EDMAC.doc' section 
+% `Paragraphed footnotes'. See our package `mfparptc.sty' for 
+% details (for the time being). 
+% 4.) Option `perpage' is just passed to `manyfoot.sty'.
+% 5.) Option `countoccurrences' provides a command \countword 
+% for a half-way solution of the problem of lemma words that 
+% occur more than once in a line. See our package `edcntwd0.sty'. 
+% (With `ednotes.sty' v1.1 you need `edcntwd0.sty' v0.31.) 
+% 
+% *Customizing:* (important change v1.1!) 
+% Appearance of notes is directed by macros \extrafootnoterule, 
+% \linesfmt etc. occurring in the following lines 
+% (each starting with \renewcommand). 
+% For customizing, copy the respective lines to your own file, 
+% remove left hand comment mark, and change the definition in the 
+% right hand pair of braces. (The definition you find there is our 
+% original one; we hope you understand from these definitions how 
+% they work in general and what the arguments are. E.g., \linesfmt 
+% applies to printing of line numbers and, originally, renders them 
+% bold-faced, followed by \enspace.) 
+% This controls identical behaviour in *every apparatus*. 
+% For changing appearance of a single apparatus without changing 
+% the remaining, see below.---Note: With v1.1, \ref has been 
+% removed from the definition of \repeatref, and a \ref in any 
+% customization of it will not work any longer. As well, earlier 
+% \linewithpage used \ref and \pageref, and this will not work any 
+% longer. \linewithpage has been replaced by \pageandline. 
+% \renewcommand{\extrafootnoterule}{\footnoterule} 
+% ---This is a `manyfoot.sty' command for separating each extra 
+% apparatus from the other ones.--- 
+% \renewcommand*{\sameline}[1]{\linesfmt{#1}} 
+% \renewcommand*{\differentlines}[2]{\linesfmt{#1--#2}} 
+% %% TODO: \linesfmt into \@EN@note!? 
+% \renewcommand*{\linesfmt}[1]{\textbf{#1}\enspace} 
+% \renewcommand*{\pageandline}[2]{#1.#2} % #1 page, #2 line. 
+% \renewcommand{\lemmafmt}[1]{#1\thinspace]\enskip} 
+% \renewcommand*{\repeatref}[1]{#1} 
+% ---E.g., for replacing repeated line numbers by non-bold slash: 
+% % \renewcommand*{\repeatref}[1]{\textnormal{/}} 
+% \renewcommand{\lemmaellipsis}{\textsymmdots}
+% \renewcommand{\notefmt}[1]{#1} 
+% Note: \notefmt, originally, takes your note just as it is. 
+% By redefinition 
+%     \renewcommand*{\notefmt}[1]{#1.} 
+% you might add an automatic closing full stop to each note. 
+% In a single note of the same apparatus, however, you might then 
+% want to close by a question mark (e.g.) instead of the fullstop. 
+% For this purpose, close that note by `?\nopunct'. \nopunct then 
+% gobbles the full stop waiting ahead. (So much as to \notefmt.)
+% ---Customizing a *single apparatus*: 
+% For changing appearance of the apparatus feeded by \Anote 
+% without changing remaining apparatuses (feeded by \Bnote etc.), 
+% take the following lines (the one with a single right brace 
+% being the last one) to your own file and remove the left hand 
+% column of comment marks. Remove then left hand comment marks 
+% of single lines containing commands whose behaviour in the 
+% apparatus you want to change. Change their definitions in 
+% right hand braces. (It is quite important never to remove 
+% right hand comment marks, as you may know!)
+% \newcommand{\Anotefmt}{% 
+% % \renewcommand*{\sameline}[1]{\linesfmt{##1}}% 
+% % \renewcommand*{\differentlines}[2]{\linesfmt{##1\textendash##2}}% 
+% % \renewcommand*{\linesfmt}[1]{\textbf{##1}\enspace}% 
+% % \renewcommand*{\pageandline}[2]{##1.##2}% ##1 page, ##2 line. 
+% % \renewcommand*{\repeatref}[1]{##1}% E.g., ... 
+% % % \renewcommand*{\repeatref}[1]{\textnormal{/}}% ... instead. 
+% % \renewcommand{\lemmafmt}[1]{##1\thinspace]\enskip}% 
+% % \renewcommand{\lemmaellipsis}{\textsymmdots}% 
+% % \renewcommand{\notefmt}[1]{##1}% 
+% } 
+% For changing the \Bnote apparatus, do the same and change 
+% \Anotefmt into \Bnotefmt. Analogues apply to \Cnote etc. 
+% ---You can, moreover, add code in the definition of \Anotefmt etc. 
+% for additional settings to be active throughout the note 
+% (including line numbers and lemma reference), 
+% e.g., for selection of a certain font type. 
+% ---`manyfoot' v1.9 offers a command \SetFootnoteHook for 
+% controlling the appearance of the whole paragraph of an apparatus 
+% in `para' or `para*' style---please see the `manyfoot' 
+% documentation for examples. `ednotes' v1.2 makes use of this 
+% through a new command \PrecedeLevelWith{X}{CODE}. E.g., 
+% \PrecedeLevelWith{A}{\textit{Var.:}} and 
+% \PrecedeLevelWith{B}{\textit{Sim.:}} (once and for all) 
+% may distinguish the variant from the similia apparatus. 
+% CODE may also be used to contol the paragraph indent of 
+% the apparatus (so the paragraphs may have different 
+% indents) or to shape the paragraph more generally 
+% (according to TeXbook chapter 14, especially pp. 101f.). 
+% To give a general rule, \PrecedeLevelWith{X}{CODE} has 
+% the same effect as \SetFootnoteHook{CODE} 
+% \DeclareNewFootnote[para]{X} would have with `manyfoot'. 
+% Without the `para' option or with the `plain' style of 
+% notes, CODE just is executed starting each note (preceding 
+% even the line number and the lemma). 
+% ---*Special characters:* As is noted in EDMAC's documentation, 
+% the en-dash for line number printing or the separating right 
+% square bracket might be coded unusually in some special font 
+% which has been chosen and so may escape being printed. Should you 
+% encounter this problem indeed, you can use the previous for remedy 
+% (e.g., change \lemmafmt). (EDMAC's solution is use of 
+% \endashchar etc. for taking these characters from the \rm font.) 
+% ---You may *redefine* most of the commands provided by the 
+% package. *Exceptions* are \donote, \<, and \>. So you might 
+% put \newcommand{\variant}{\Anote} or even (for TeXperts) 
+% \let\variant\Anote into your file (after `ednotes.sty' has been 
+% read). No problem about nesting will arise (as did with EDMAC). 
+% EDMAC's suggestion to make <...> a shorthand, however, would 
+% conflict with our lemma mechanism. (Coexistence would be possible 
+% by suitable use of braces and repeating present definitions 
+% after change of <'s catcode.)
+%
+% *A problem:* 
+% With run-in-paragraph footnotes (options `para' or `para*'), notes 
+% may end too deep on the page or (with `longtable.sty') even overlap 
+% with main text. `ednotes.sty' shares this "feature" with EDMAC and 
+% LEDMAC. Output gets worse as the number of paragraphed-footnote 
+% series increases. `manyfoot.sty' version 1.7 (!) accounts for this 
+% by a command \ExtraParaSkip (as an interim solution). This command 
+% reserves additional vertical space for the notes (so there is less 
+% space for main text---at the expense of too large empty space on 
+% some pages). After `ednotes.sty' (or `manyfoot.sty') has been 
+% loaded (i.e., below \usepackage...), type `\ExtraParaSkip{<skip>}' 
+% (still in the preamble) where <skip> may be any glue parameter. 
+% <skip> may be a multiple of any absolute space unit (e.g., `4pt' or 
+% `2mm'), it may even be a multiple of a space unit depending on the 
+% font size of notes (\footnotesize)---like `em', `ex', or 
+% `\normalbaselineskip' (e.g., `.5\normalbaselineskip'). (However, 
+% stretch and shrink of, e.g., \normalbaselineskip are ignored.) 
+% Experiment with choices for <skip> such that notes neither overlap 
+% with main text nor hang too deep on the page. The most safe choice 
+% is `\ExtraParaSkip{.5\normalbaselineskip}'. 
+% ---Manyfoot.sty did something similar before; i.e., it reserved 
+% .5\normalbaselineskip (with respect to \footnotesize) for the notes. 
+% This may not be needed on some pages (on such pages there may be 
+% too much empty vertical space). 
+% ---For the best solution you should, when your work is ready and 
+% only needs optimization of formatting, type 
+% \ExtraParaSkip{-.5\normalbaselineskip} 
+% (to remove the space that Manyfoot.sty reserves) and then insert 
+% \pagebreak's in your main text to avoid overful pages. 
+% ---We formerly offered a command \MFparaxbuffer in file 
+% `mfparxsp.sty' instead. This could be used once only in the 
+% document preamble. \ExtraParaSkip does not have this limitation. 
+% This allows, e.g., first setting a "default" value and changing it 
+% under certain conditions, e.g.: 
+% \ExtraParaSkip{<skip1>} ... \if... \ExtraParaSkip{<skip2>} ... \fi 
+% (Thanks to Florian Kragl who presented a similar first remedy for 
+% the problem.) 
+% 
+% *The problem of oscillating page breaks:* 
+% In typesetting critical editions, there is an increased danger 
+% of page break oscillations, causing wrong numberings, 
+% placements, and cross-references. Our package `lblchng1.sty' 
+% (same CTAN directory) offers help with this. However, 
+% `ednotes.sty' v1.1 takes over most of the job from 
+% `lblchng1.sty'. We still recommend to *read the file* 
+% `lblchng1.sty' on how to use the messages from `lblchng1.sty' 
+% and `ednotes.sty' on page number changes (be sure that it is 
+% v0.32 or higher). Yet the messages may suffice. Just look at the 
+% final messages on screen or in .log.
+% 
+% *A problem with `hyperref.sty':* 
+% To guarantee compatibility with `hyperref', updating lineno.sty 
+% to v4.3 is recommended. 
+% 
+% *Note on EDMAC:* 
+% `edmac.doc' is a macro package by John Lavagnino and 
+% Dominik Wujastyk made for critical editions to be used in presence 
+% of Plain TeX only. We refer to the macros and documentation of 
+% this package by `EDMAC'. There is an enhancement `edmacfss.sty' 
+% for additionally employing the New Font Selection Scheme (NFSS) 
+% from LaTeX2e. With `edmacfss.sty', some LaTeX commands work by 
+% accident. However, it replaces LaTeX's \end by PlainTeX's \end, 
+% so LaTeX environments don't work. Moreover, 
+% EDMAC defines its own output routine in place of LaTeX's, 
+% so LaTeX's page assembly and related commands (\marginpar ...) 
+% are disabled. EDMAC still provides facilities 
+% (columnar footnotes, endnotes, sublines) which are neither 
+% implemented here nor in packages `manyfoot' and `lineno' 
+% on which the present one is based. However, there are authors 
+% who have had a desire to stay in LaTeX's paradise and to enjoy 
+%% TODO: Hilbert translation 
+% EDMAC features at the same time. (E.g., edition may be only part 
+% of your document, or you want to use many LaTeX packages.)
+% Fortunately, Christian was led to packages `manyfoot' and `lineno' 
+% which implement the most desirable of EDMAC's facilities for use 
+% with LaTeX. A version of EDMAC's \text and assembly of notes 
+% remained to be done. We even go beyond EDMAC concerning lemma 
+% substitutes and overlapping lemmas. 
+% ---For explanation of present solutions, we sometimes refer to 
+% EDMAC where similar problems are dealt with in similar but 
+% sometimes essentially differing ways. Therefore, knowledge of 
+% EDMAC may foster your understanding commands and remarks 
+% presented here, but it is not required. 
+% ---Dominik maintains a homepage for EDMAC and related software: 
+% http://www.homepages.ucl.ac.uk/~ucgadkw/edmac/
+% 
+% *Comparison with LEDMAC:* 
+% (Cf. http://ednotes.sty.de.vu and `ednotugb.pdf'.)
+% Peter Wilson's LEDMAC ports EDMAC to LaTeX, i.e., you get 
+% almost exactly EDMAC *functionality* and same *user interface* 
+% as in good old EDMAC (some slight changes of command names 
+% were necessary). Thus it offers a very easy switch to LaTeX 
+% for EDMAC addicts and is superior in functionality to `ednotes.sty' 
+% where EDMAC is (columnar footnotes, endnotes, sublines, etc.? 
+% --first two might change over the years). `ednotes.sty' might 
+% be favoured if you really need overlapping lemmas, and we tried 
+% to offer further user-friendly features as spelled out above. 
+% --Some users want to edit tables. For EDMAC there is the 
+% TABMAC package providing special commands for this. A TABMAC 
+% port is part of LEDMAC. This is nice for EDMAC/TABMAC addicts. 
+% Our additional package `edtable.sty' allows for lemmas in (some) 
+% LaTeX tabular environments and numbers their rows as if they were 
+% lines. This is nice for those who only know the LaTeX tabular 
+% environments. However, TABMAC and its mirror in LEDMAC offer 
+% facilities which are not provided by LaTeX/ednotes/edtable. 
+% --LEDMAC *implementation* is very close to EDMAC's as well, 
+% differing very much from `ednotes.sty', especially concerning 
+% use of auxiliary files. However, this seems to have no practical 
+% effects. On very old machines, EDMAC/LEDMAC might be slower, while 
+% Ednotes might cause memory overflow with small TeX versions and 
+% many notes. Peter Wilson [3/3 2004] estimates that rather 
+% EDMAC's/LEDMAC's typesetting everything twice might be a 
+% disadvantage in comparison with `ednotes.sty'. 
+% ---In 2004 LEDMAC has been enhanced considerably beyond the 
+% functionality of EDMAC and `ednotes.sty'. 
+% It now also includes indexing by line as well as by page, 
+% a port of Wayne Sullivan's EDSTANZA, new options for line 
+% numbering, a minipage-like environment (which may break across 
+% pages) such that remarks are printed immediately after some piece 
+% of edited text (a letter, e.g.), and "sidenotes". 
+% Finally an extension package `ledpar' adds parallel typsetting. 
+% --At least for some time LEDMAC will be more user-friendly 
+% in providing all functions in a single file with *one* 
+% *printable* documentation file.                          %% TODO 
+% On the other hand, packages we build on are still being enhanced 
+% in functionality by their authors.

+%% Acknowledgements 
+% 
+% Christian saved me from most of the work by having found 
+% packages `lineno.sty' by Stephan I. B"ottcher and `manyfoot.sty' 
+% by Alexander I. Rozhenko which do the output stuff. Thanks to 
+% Christian, Stephan and Alex! I appreciate their work (especially 
+% Stephan's approach to adding and remembering line numbers), and I 
+% admire John Lavagnino's and Dominik Wujastyk's work on EDMAC. 
+% I am also grateful for their encouragement. U.L. 
+% 
+% Moreover I am much indebted to Stephan B"ottcher and Alex
