+\subsection{Compounds and Broken Lines}
+
+The mechanism provided by the package requires the delimited expression
+to appear as an uninterrupted compound. In particular, the expression cannot
+span several lines in a multi-line equation or several columns in a matrix.
+The same restriction applies to the elementary |\left| and |\right| construct.
+In cases where delimited expressions are torn apart across several blocks,
+the delimiters have to be typeset individually.
+The package offers a mechanism to display individual delimiters
+of a given delimiter set. It also assists in maintaining
+the same type and size across blocks.
+Being able to display individual delimiters of defined delimiter sets
+offers a broad range of (ab)use.
+
+Individual delimiters of a set can be selected and displayed
+by specifying appropriate flags,
+for example:
+%
+\[
+|\brk(|\to{(},\qquad
+|\brk)|\to{)}
+\]
+%
+These flags can be combined with the size specifier
+or other bracket modifiers,
+e.g.:
+%
+\[
+|\brk^3(|\to{\biggl(},\qquad
+|\brk[s]^2)|\to{\Bigr]}
+\]
+%
+This enables to conveniently split delimited expressions over blocks of code,
+e.g.:
+%
+\[
+|\brk[s]^3(\frac{A}{B}|\ldots\Big/\mkern-9mu\Big/\ldots|\frac{C}{D}\brk[s]^3)|
+\to
+\biggl[\frac{A}{B}\cdots\bigg/\mkern-12mu\bigg/\cdots\frac{C}{D}\biggr]
+\]
+%
+Here, the type and modifiers specifying the delimiter set
+are repeated for all individual delimiters.
+To simplify such expressions and their maintenance,
+the package provides global registers which store
+the type and size of delimiters.
+With those, the above expression can be abbreviated as:
+%
+\[
+|\brk[s]^3[|\ldots\big/\mkern-6mu\big/\ldots|\usedelim]|
+\quad\text{or}\quad
+|\brk[s]^3[|\ldots\big/\mkern-6mu\big/\ldots|\brk]|
+\]
+%
+Here, |\usedelim]|, alternatively |\brk]|,
+closes the delimiter set with
+the type and options previously specified by |\brk...[|.
+For nesting purposes, there also exists a more elaborate
+solution using registers, see below.

-\subsection{Inline Usage}
-\label{sec:delimcommands}
+\subsection{Delimiter Sets and Presentation Flags}
+\label{sec:flags}
+
+The package provides commands to represent various delimiter sets,
+see \secref{sec:inline} and \secref{sec:declare} below.
+Their display can be modified systematically by specifying flags.
+A delimiter set |\|\emph{name}, e.g.\ |\brk|, is typically invoked by
+a sequence like:
+%
+\[
+|\|\emph{name}\ \emph{flags}\ |{|\emph{expr1}|}||{|\emph{expr2}|}|\ldots
+\]
+%
+where \emph{expr(n)} are the terms to be enclosed by the delimiters
+and the optional \emph{flags} adjust the presentation of delimiters.
+The \emph{flags} are described as follows:
+
+First, a size modifier flag controls the size of the delimiters
+to be displayed. It can take one of the following values:
+%
+\[
+\begin{aligned}
+|0|&\qquad \text{default size}
+\text{ (0.96 times default line height)}
+\\
+|!|, |+|, |^1|&\qquad \text{size }|\big|
+\text{ (1.2 times default line height)}
+\\
+|^2|&\qquad \text{size }|\Big|
+\text{ (1.8 times default line height)}
+\\
+|^3|&\qquad \text{size }|\bigg|
+\text{ (2.4 times default line height)}
+\\
+|^4|&\qquad \text{size }|\Bigg|
+\text{ (3.0 times default line height)}
+\\
+|^|\emph{n}, |^{|\emph{x}|}|&\qquad \text{flexible size adjustment
+(\emph{n}=|0|\ldots|9|; \emph{x}: decimal number)}
+\\
+|_{|\emph{h}|}|&\qquad \text{adjustment to absolute height \emph{h} (centred)}
+\\
+|*|&\qquad \text{variable size }|\left...\right|
+\end{aligned}
+\]
+%
+The intended delimiter size is stored as the dimension register:
+%
+\[
+|\delimsize|
+\]
+%
+It may be used to adjust spacing within the delimiter set
+proportional to the size of the delimiters.
+Note that the actual size of delimiters may deviate
+depending on availability within the given font.
+Note further that the size cannot be determined for variable-size delimiters
+(`|*|') and thus size |\Big| is assumed for this case.
+Note finally that the sub/superscript styles are not taken into
+account and |\delimsize| applies to the default case |\textstyle|.
+The package also supplies a macro to add horizontal glue
+proportional to the intended delimiter size:
+%
+\[
+|\kerndelim{|\emph{width}|}|
+\]
+%
+Here, \emph{width} is the amount of horizontal glue
+in units of mu scaled by the ratio of |\delimsize|
+and the current math font height.
+The macro does adjust for the selected script style.
+
+Second, a delimiter selection flag is used to pick out
+and display just one individual delimiter within the set.
+It can take one of the following values:
+%
+\[
+\begin{aligned}
+|(|&\qquad \text{left delimiter}
+\\
+\textvert, |,|&\qquad \text{first intermediate delimiter}
+\\
+|)|&\qquad \text{right delimiter}
+\\
+|?|\emph{n}&\qquad \text{\emph{n}-th delimiter (starting with |0|: left)}
+\end{aligned}
+\]
+
+Third, register flags store are retrieve delimiter
+for splitting the across blocks or lines:
+%
+\[
+\begin{aligned}
+|[|&\qquad \text{store delimiter type to register `|.|',
+display left delimiter (same as `|>.(|')}
+\\
+|]|&\qquad \text{display right delimiter stored in default register `|.|'
+(same as `|<.)|')}
+\\
+|>|\emph{r}, |>{|\emph{reg}|}|&\qquad \text{store delimiter type
+in register \emph{r} or \emph{reg}}
+\\
+|<|\emph{r}, |<{|\emph{reg}|}|&\qquad \text{retrieve delimiter type
+from register \emph{r} or \emph{reg}}
+\end{aligned}
+\]
+%
+A register stores the type of delimiter set (|\|\emph{name}),
+the desired size (except for variable size `|*|')
+as well as the math class of the compound (`|'|' vs. `|"|', see below).
+A stored register can be retrieved and displayed by the macro:
+%
+\[
+|\usedelim|\,\emph{r}\ \emph{sel}
+\quad\text{or}\quad
+|\usedelim|\{\emph{reg}\}\emph{sel}
+\]
+%
+Here, \emph{sel} is a flag to select an individual delimiter, see above.
+
+In addition, there are some general purpose flags:
+%
+\[
+\begin{aligned}
+|.|&\qquad \text{terminates flag processing}
+\\
+|:|&\qquad \text{enclose delimiter set in block
+(for using total box dimensions)}
+\\
+|'|&\qquad \text{render delimiter set as }|\mathopen|\text{ and }|\mathclose|
+\\
+|"|&\qquad \text{render delimiter set as }|\mathinner|
+\\
+|-|&\qquad \text{display phantom delimiters (for individual delimiters)}
+\end{aligned}
+\]
+
+Please note the following:
+%
+\begin{itemize}
+\item
+A delimiter selector (including the combined flags `|[|' and `|]|')
+terminates flag processing,
+therefore all relevant flags must be specified before it.
+\item
+Parsing also stops with the opening of the first term argument
+by means of the opening brace `|{|'.
+\item
+Parsing can also be terminated manually by specifying the flag `|.|'
+(in case the opening brace `|{|' for arguments is missing for whatever reason).
+\item
+Any other letter or token at the location of \emph{flags}
+is interpreted as an unrecognised flag and triggers a compiler error.
+For instance, |\brk{x}| must not be abbreviated as |\brk x|
+because `|x|' would be interpreted as a flag
+(it might be abbreviated as |\brk.x|).
+\item
+The legacy size modifier flags `|1|' \ldots `|4|'
+provided for backward compatibility have the same effect as `|^1|'\ldots`|^4|'.
+\item
+The phantom delimiter flag `|-|' does not work for variable size.
+It is intended for reserving space for individual delimiters
+when they are composed manually into sets (e.g.\ across lines).
+\item
+Technically, individual delimiters can be produced in the variable size version
+(even though it may defeat the purpose of the delimiter selection mechanism).
+One has to pay attention when using
+only the opening or only the closing delimiters from the package
+and counterbalancing it by direct code for the opposite side.
+This is because `|*(|' and `|*)|' do not directly translate to
+|\left|\emph{delim} and |\right|\emph{delim}
+due to proper spacing, see \secref{sec:spacing}.
+Instead, they translate to:
+%
+\[
+\begin{aligned}
+|*(|&\to|\mathopen{}\mathclose\bgroup\left|\emph{delim}
+\\
+|*)|&\to|\right|\emph{delim}|\egroup|
+\end{aligned}
+\]
+%
+One should use analogous code to complete the manual variable size block.
+
+Note that similar restrictions apply to using the flag `|:|'
+for block enclosure which uses |\bgroup| and |\egroup| as well.
+
+As it does not make much sense to use variable-size (`|*|')
+and block (`|:|') compounds for individual delimiter selection,
+the state of these flags is not stored in the global registers.
+\end{itemize}
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Inline Declarations}
+\label{sec:inline}
The package provides three general purpose commands
to compose delimiter sets with one, two or three encapsulated expressions:
%
\[
\begin{aligned}
-&|\delim{|\emph{l}|}{|\emph{r}|}|\emph{size}|{|\emph{expr}|}|
+&|\delim{|\emph{l}|}{|\emph{r}|}|\emph{flags}|{|\emph{expr}|}|
\\
&|\delimpair{|\emph{l}|}{|\emph{m}|}{|\emph{r}|}|
-\emph{size}|{|\emph{expr1}|}{|\emph{expr2}|}|
+\emph{flags}|{|\emph{expr1}|}{|\emph{expr2}|}|
\\
-&|\delimtriple{|\emph{l}|}{|\emph{m1}|}{|\emph{m2}|}{|\emph{r}|}|
-\emph{size}|{|\emph{expr1}|}{|\emph{expr2}|}{|\emph{expr3}|}|
+&|\delimtriple{|\emph{l}|}{|\emph{m}|}{|\emph{n}|}{|\emph{r}|}|
+\emph{flags}|{|\emph{expr1}|}{|\emph{expr2}|}{|\emph{expr3}|}|
\end{aligned}
\]
%
The expression(s) \emph{expr(n)} will be surrounded by the
delimiters \emph{l} and \emph{r}
and, in the case of more than one expression,
-they will be separated by the delimiters \emph{m(n)}:
+they will be separated by the delimiters \emph{m}, \emph{n}:
+%
\[
\emph{l}\ \emph{expr}\ \emph{r},
\qquad
\emph{l}\ \emph{expr1}\ \emph{m}\ \emph{expr2}\ \emph{r},
\qquad
-\emph{l}\ \emph{expr1}\ \emph{m1}\ \emph{expr2}\
-\emph{m2}\ \emph{expr3}\ \emph{r}
+\emph{l}\ \emph{expr1}\ \emph{m}\ \emph{expr2}\
+\emph{n}\ \emph{expr3}\ \emph{r}
\]
-Here, \emph{l} and \emph{r} have to be
-math delimiters (symbols which can be used for |\left| and |\right|) or
-the dot `.' for the null delimiter.
-The separators \emph{m(n)} can be plain math delimiters as well, but they can
-also be compound expression of the form |[|\emph{class}|]|\emph{delim}
-where \emph{class} specifies
-the intended math class of the delimiter \emph{delim}:
+Here, \emph{l}, \emph{r}, \emph{m}, \emph{n}
+should be math delimiters \emph{delim}
+(elementary symbols which can be used for |\left| and |\right|)
+or the dot `|.|' for the null delimiter.
+The delimiter set expression can be adjusted in two ways:
+
+First, size adjustment
+for the delimiters \emph{l}, \emph{r}, \emph{m}, \emph{n}
+can be suppressed by a starred variant:
+%
+\[
+|{*|\emph{token}|}|
+\qquad\text{or}\qquad
+|{*{|\emph{expr}|}}|
+\]
+%
+This allows to use an arbitrary \emph{token}
+or a compound expression \emph{expr} in place of a delimiter \emph{delim}.
+This is useful when a delimiter character should not adjust in size
+(e.g.\ commas), or if a flexible-size version of the character

-For now, only the English and French languages are fully supported. With other languages, you benefit from the \TO{babel} facilities, but the \enquote{tango words} will remain defined by:

-If you want to use tango with a new language, here is what you can do:

+Although any language option recognized by babel will (in principle) be taken into account as soon as it is passed to tango, the translation of these reserved words only happens for the following languages:
+\begin{itemize}
+\item\TO{french};
+\item\TO{english, british, american, canadian, australian, newzealand};
+\item\TO{german, ngerman, naustrian, nswissgerman};
+\item\TO{italian};
+\item\TO{spanish}.
+\end{itemize}
+
+Other languages benefit from babel's facilities, but tango's reserved words are not translated.
+So here's what concerned users can do.
+
\begin{enumerate}
\item Translate these names in your language (for now it is done only for the french language), using \verb+\renewcommand+.
\item (Better) Mail me all the necessary information (at least babel language option used and your translation of the tango names) and I will adapt the tango class to your language.

Un message d'erreur sera généré par la classe tango si celle-ci n'a reçu aucune option de langue à transmettre à \TO{babel} ; si vous ignorez ce message, vous devrez travailler sans aucun motif de césure.
