% *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' (v1.9+) 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. Note that this default suppresses 
% hyphenation of the first word of a lemma tag.) 
% 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} 
% ---E.g., for enabling hyphenation of first word of lemma tag: 
% % \renewcommand*{\linesfmt}[1]{\textbf{#1}\enspace
% %                              \hspace*{0pt}}
% ---Last line works like german.sty's \allowhyphens. 
% \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.)
%
% *Your shorthands:*
% \Anote etc. prevent editorial notes from appearing in the 
% table of contents when such commands (\Anote etc., i.e.) 
% appear in a heading (e.g.). But when you define a shorthand macro 
% (using \newcommand) that has an optional parameter and \Anote 
% or so in the defining code, something more is needed to have 
% the lemma, without the note, in the table of contents (or ...) 
% E.g., you might \newcommand*{\variant}[1][A]{\Anote{#2}{#1}}
% so \variant{res} works like \Anote{res}{A} and \variant[B]{res}
% works like \Anote{res}{B}. ednotes v1.22 offers two solutions 
% to this problem: 
% 1. You can precede your shorthand with \RobustTestOpt whenever it 
%    appears in a "moving" argument like a chapter heading -- 
%    \RobustTestOpt\variant{res}    as well as 
%    \RobustTestOpt\variant[B]{res} , e.g. 
% 2. You can save yourself from caring for \RobustTestOpt by using 
%    \NewEdnotesCommand instead of \newcommand -- 
%    \NewEdnotesCommand*{\variant}[2][A]{\Anote{#2}{#1}}
% These facilities work only when the shorthand has an *optional* 
% parameter and at least one *mandatory* parameter -- well, if it 
% doesn't have, you can use \RobustTestOpt if you put a pair of 
% braces after the shorthand macro name, this would work as well. 
% 
% *Known problems:* 
% 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). The warnings from ednotes.sty may suffice. 
% Just look at the final messages on screen or in .log. 
% -- You can overcome such problems using \pagebreak 
% (Standard LaTeX) or \warningpagebreak (from present package) 
% -- force the earlier page break! 
% \warningpagebreak works like Standard LaTeX \pagebreak, it just 
% adds a reminder for the case that such a manual page break 
% may become bad after revisions of your entire work. 
% 
% *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 
% Rozhenko for their co-operation in reducing the number of 
% package files that `ednotes.sty' needs. (This was 2004, 
% version v1.0.)
% 
% For pointing out errors and problems, we are grateful to test 
% users Robert Alessi, Sergei Mariev---see version history. 
% Florian Kragl contributed to now `manyfoot.sty's \ExtraParaSkip 
% as described above. v1.1 is due to problems that Roy Flechner 
% reported. v1.12 is due to Hillel Chayim Yisraeli's discovery 
% of spurious footnote marks.
