+%
+% *Requirements/overview:*
+%
+% The package is made for the background of the LaTeX2e macro
+% package and enhances functionality of the following packages:
+% 1.) Stephan I. B"ottcher's `lineno.sty' for printing line
+% numbers in the margin and a \label version \linelabel
+% relating labels to line numbers;
+% 2.) our `ednotes.sty' for indicating variant readings and
+% other editorial remarks in separate footnote apparatuses;
+% 3.) David Carlisle's `longtable.sty' for multi-page tables.
+% %% TODO: supertabular etc.!?
+% 4.) our `ltabptch.sty' for a patch of `longtable.sty'
+% (i.e., optionally, see below).
+%
+% Actually, only the first package is necessary for using the
+% present one. The present one needs your line numbering commands
+% according to the first one and its documentation to which we
+% refer here. We likewise refer to the remaining packages for the
+% details of their functionality.
+%
+% `lineno.sty' version 4.1 and (in case it is used) `ednotes.sty'
+% version 0.8 (onwards) are needed. For obtaining recent versions
+% of required packages, see the CTAN folder
+% /macros/latex/contrib/ednotes.
+%
+% *Install/load:*
+% 1.) To be used, the present file must be put into a folder
+% that (La)TeX searches. You should have obtained a file
+% containing more detailed hints about this.
+% 2.) We recommend loading this file *not* by
+% \usepackage[<options>]{edtable} but by loading `lineno.sty'
+% or `ednotes.sty' with package option `edtable'.
+% 3.) To use the package options `longtable' and
+% `nolongtablepatch' that are described below, enter them
+% as options for `lineno.sty' or `ednotes.sty'.
+%
+% *User Commands:*
+%
+% 1. The package defines an environment `edtable' -- for its
+% syntax we consider two cases:
+% (a) Let <stdtable> be a tabular environment "like `tabular'".
+% "Like" here means: (i) we have tested it with `tabular', but
+% it should work with many more (e.g., from the `array' and
+% `tabularx' packages) -- which share certain properties of
+% implementation and requirements. Sorry, you must try, or we
+% hope you will (and tell us). (For wizards: <stdtable> may
+% probably be anything using a single \halign and \tabskip=0pt.)
+% Definitively:
+% (ii) LaTeX's standard `array' and other environments are *not*
+% "like" `tabular'. Namely, environments that work only in math
+% mode are not meant here. They are considered below in `b.'.
+% (iii) `longtable' from the `longtable' package of the `tools'
+% bundle neither is meant. An option of the present package
+% deals with it as described below. Neither `supertabular' is
+% meant.
+% (iv) In general, usage with tabular environments that can
+% break across pages as in (iii) is not recommended, at least
+% when working with `ednotes.sty'. Even if some worked here, a
+% shortcoming with `ednotes.sty' would be that the footnotes can
+% appear on bad pages.
+% -- Now the syntax is:
+% \begin{edtable}{<stdtable>}<args><entries>\end{edtable}
+% -- where <args> and <entries> are usual arguments and entries
+% for <stdtable>. So an example is:
+% \begin{edtable}{tabular}{cc}
+% left upper & right upper \\ left lower & right lower
+% \end{edtable}
+% This produces just what <stdtable> does in an extra line,
+% only adding line numbers in the margin and processing `ednotes'
+% commands in the entries appropriately.
+% (b) Let <stdarray> be an "array environment" like -- standard
+% LaTeX's `array'! "Like" here means (i) ... analogously to
+% <stdtable> above. (ii) "Text" ... oh, sorry, this is not clear
+% to me at present, and I am in a hurry. %% TODO
+% (iii) Nothing from the `amsmath' package seems to work here,
+% sorry, I have tried a lot ... (iv) For standard LaTeX's
+% `eqnarray', it is better to try the `linenomath' environment
+% of `lineno.sty' [with package option `mathlines']. Its
+% modifications in `amsmath' produce (at best) a spurious line
+% number with the `linenomath' environment (up to now).
+% -- Now the syntax is:
+% \begin{edtable}[<$$$>]{<stdarray>}
+% <args><entries>\end{edtable}
+% -- where <args> and <entries> are usual arguments and entries
+% for <stdarray>. <$$$> can be one of `$' or `$$'. Indeed, the
+% <stdtable> syntax above (without [<$$$>]) *does not work*
+% inside $...$ or $$...$$. -- An example:
+% \begin{edtable}[$$]{array}{cc}
+% a_{11} & a_{12} \\ a_{21} & a_{22}
+% \end{edtable}
+% Now, this produces just what <stdarray> does in an extra line
+% etc. as with <stdtable>. However, \linelabel and `ednotes.sty'
+% footnotes may need the `mathrefs' option of `lineno.sty'. For
+% the difference between `[$]' and `[$$]', see below.
+%
+% 2. When working with `ednotes.sty', in
+% \Anote{L1\<L2\>L3}{NOTE}
+% L2 may contain &'s and \\'s, but L1, L3 must not! Analogously
+% for \Bnote, etc., \Anotelabel...\donote..., etc. -- Well this
+% holds for <stdtable>, hardly for <stdarray> ... %% TODO
+%
+% 3. On positioning: You may have wondered about `extra line'
+% above. This means that `edtable' starts a new line at
+% \begin{edtable} and at \end{edtable}. %% TODO: sure!?
+% (a) It should be placed within a `center', `flushleft', or
+% `flushright' environment for proper (vertical) spacing, but
+% also works without. However, with <stdarray> and optional
+% parameter `$$' of `edtable' (i.e., \begin{edtable}[$$]...),
+% you can obtain the usual math display spacing *within a
+% paragraph*; especially, the vertical space is less when the
+% previous line is short ... and so on.
+% (b) Horizontal positioning of line numbers (usually) needs a
+% second run (after changing a table)! %% TODO: automatic warning.
+% (For wizards: It may fail if some of \leftskip, \rightskip,
+% \linewidth, and \@totalleftmargin are used in an unusual way.)
+% A <dimen> register \ETextraoffset is provided whose value is
+% 0pt by default and which additionally moves line numbers
+% to the left (right) if given a positive (negative) value.
+% %% TODO: any use?
+%
+% *Package options:*
+%
+% 1. Option `longtable' adjusts the `longtable' environment
+% defined by David Carlisle's longtable.sty for use with
+% `lineno.sty' and `ednotes.sty'. The option makes `longtable'
+% environments appear with line numbers in the margin, according
+% to `lineno.sty', and process `ednotes.sty' commands if line
+% numbering is active according to `lineno.sty'.
+% [We maintain an alternative package with just this function
+% in a slightly different implementation.] %% -> ulnltab.sty.
+% Lemmas may go across table entries as with `edtable' (see above).
+% ---There might be options like `supertabular' for adjusting
+% other tabular environments that cannot be handled by the
+% `edtable' environment provided here---they have not been
+% implemented yet! %% TODO
+%
+% 2. Option `nolongtablepatch' avoids loading/asking for
+% `ltabptch.sty'. I.e.: according to LaTeX bugs database,
+% tools/3180 and tools/3485, there have been problems with
+% vertical spacing around `longtable' environments. By default
+% the present package loads our `ltabptch.sty' or asks for it.
+% Option `nolongtablepatch' overrides this. This is useful when
+% you don't want to have the patch, especially when you use an
+% "emergency stop" installation of TeX.
+%
+% *Wizard interface:*
+% Macros \@ET@makeLineNumber, \@ET@use@outerhook,
+% \@ET@execute@outerhook, \@ET@ampnotes \@ET@startlinewith,
+% \@ET@trivialize@linelabel are provided as tools for adjusting
+% tabular environments for use with `lineno.sty' and
+% `ednotes.sty'. \@ET@step@linenumber is \let \stepLineNumber
+% (from `lineno.sty'), but could be used as a hook for
+% something different. See Environment `edtable' and Option
+% `longtable' below for examples of application.
+% %% TODO: specification here.
+%
+%
+%% * Acknowledgements: *
+%
+% Stephan I. B"ottcher told us how to do it in extensive discussion
+% and by providing some first code lines. We changed these essentially
+% in some respects, but kept his general ideas and some parts of his
+% macros, the latter even without knowing what we are doing.
+%
+% v1.3 is due to a request by Martin Brandenburg.
+%
+% * Now for internals: *
+%
+\NeedsTeXFormat{LaTeX2e}[1994/12/01]
+% 1994/12/01: \newenvironment* etc. %% TODO: more recent needed?
+\ProvidesPackage{edtable}[\filedate\space v\fileversion\space
+ arrays with lineno + ednotes (ul)]
+%
+% Alternative ideas for implementation:
+% 1. There is a German package `TABMAC' enhancing `EDMAC' (cf.
+% documentation of `ednotes.sty'). We could have rewritten its
+% macros so it would work with `lineno.sty' and `ednotes.sty'
+% in place of `EDMAC'. [TODO: "tabmac.sty"]
+% 2. We redefine `longtable' by Option `longtable' because
+% there seems to be only one reasonable use of the `longtable'
+% environment in the course of a critical edition. This may be
+% different for environments like `array' and `tabular' which
+% can be used within text lines. Therefore, these environments
+% are not redefined.
+% 3. One might use \everycr, however: (a) it is executed
+% before the first row, (b) it is executed in fake lines that
+% `longtable' uses.
+% 4. As an alternative to \everycr, there is the approach of
+% redefining \cr and \crcr for setting \noalign. This needs
+% redefining \@tabularcr etc.---not nice. We use this approach
+% here for `longtable' which uses a stretching \tabskip.
+% For \tabskip=0pt, we attach line numbers by a template.
+%
+% \RequirePackage{lineno}[2004/10/06]
+% Wanted to check lineno version--causes unknown option error.
+% See LaTeX bug latex/3730.

+% Special \halign:
+% For `array' etc., we insert line numbers by a leftmost template.
+% @{...} in the last argument of `array' etc. is difficult for this
+% since `tabular*' has an additional argument. So we redefine
+% \halign to put something to the right of the next \bgroup.
+% Now, as a macro, \halign would break in an \edef or \xdef.
+% Horribly, this danger has become quite real in longtable.sty's
+% definition of \LT@bchunk. Only its latest version 4.10 has
+% preceded \halign by a \noexpand (for mathtext.sty which
+% redefines \halign as well). We need not rely on such a
+% provision if we let \halign expand to \the<token register>
+% for some token register. However, using \toks@ or \@temptokena
+% is neither very safe---might be filled by macro ahead with
+% something new. So reserve an own token register.
