 %% * USAGE: *
-% 
-% * Most simple: * 
-% --If you are working with ednotes and want to use its

-% * Switch off and on: * 
-% To reduce danger resulting from missing error messages

-% off by \NoNotesToMath where you don't expect to need them. 
-% You may switch them on again by \NotesToMath where you want

-% 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

-% `tabularx' packages) -- which share certain properties of 
-% implementation and requirements. Sorry, you must try, or we

 %% ==== How to Number Lines Pagewise ====
 %% The basic idea of 'lineno''s pagewise numbering is:
 %% \begin{enumerate}
-%%   \item Each numbered line of the document is identified 
+%%   \item Each numbered line of the document is identified
 %%         by a unique counter value, an ``absolute" number.
-%%   \item For each page (and column), the range of absolute 
-%%         line numbers occurring on them is recorded 
-%%         (or actually: the first and the last number). 
-%%   \item The ``public," ``human-readable" (``pagewise") 
-%%         format of a given absolute line number $l$ is generated by 
-%%         (\textit{i})~finding the page (and column) with 
-%%         first number $n$ and last number $k$ such that 
-%%         $n\leq l\leq k$, 
+%%   \item For each page (and column), the range of absolute
+%%         line numbers occurring on them is recorded
+%%         (or actually: the first and the last number).
+%%   \item The ``public," ``human-readable" (``pagewise")
+%%         format of a given absolute line number $l$ is generated by
+%%         (\textit{i})~finding the page (and column) with
+%%         first number $n$ and last number $k$ such that
+%%         $n\leq l\leq k$,
 %%         (\textit{ii}) ``printing" $l-n+1$ in ``columnwise"
-%%         mode, otherwise $l-m+1$ where $m$ is the first 
-%%         absolute line number in the left-hand column of the 
+%%         mode, otherwise $l-m+1$ where $m$ is the first
+%%         absolute line number in the left-hand column of the
 %%         same page.

-%% The footnote text is typeset, including numbering its 
-%% lines at each end of a footnote paragraph. When the 
-%% footnote text has been sent into the `\insert' register, 
-%% numbering of main text lines is resumed. 
-%% 
-%% Up to v0.4 (a development version), we used the \emph{same} 
-%% absolute counter for main text and footnote lines. 
-%% When a page $p$ has more than one main text line and the first 
-%% one has a long footnote continued on the next page~$p+1$,

-%% 'lineno''s procedure can be revived by numbering 
-%% main text lines and footnote lines independently 
-%% from each other. We use \emph{two} absolute counters,

 %%   \item[Logging:]
