+\subsubsection{Defining knowledge-aware macros}
+\label{subsubsection:knowledgenewcommands}
+
+It is possible to use the \cs\kl\ command inside , and in math mode (however, the "quotation notation" should really be avoided). 
+Nevertheless, this may cause problematic results in various situations. For this reason, specialized tools are offered.
+
+In this first section, we describe the simplest way to define macros that are linked to "knowledge".
+This covers almost all situations, as long as one is not interested in having the knowledge dependant of the parameters of the macro.
+In the subsequent sections, some more explanations are given covering the case of parameters.
+
+
+\knowledgenewcommand\floor[1]{\cmdkl{\lfloor}#1\cmdkl{\rfloor}}
+
+\paragraph*{The use through an example}\AP
+Let us define the $\intro*\floor{x}$ command representing the 
+floor rounding of~$x$, and use it in $\floor{1.5}$. This is achieved by first defining a macro \cs\floor\ (for instance in the preamble):
+\begin{code}
+	\cs\knowledgenewrobustcmd\cs\floor[1]\{\cs\cmdkl\{\cs\lfloor\}\#1\cs\cmdkl\{\cs\rfloor\}\}
+\end{code}\noindent
+and then use it in a natural way:
+\begin{code}
+    \cs\AP\ Let us define the \$\cs\intro*\cs\floor\ x\$ command representing the floor rounding of \$x\$,
+    and use it in  \$\cs\floor\{1.5\}\$.
+\end{code}\noindent
+There, we used a special command, \cs\knowledgenewrobustcmd, which is similar to the  \cs\newrobustcmd\footnote{It has the same syntax as \cs\newcommand\ and should always be used instead as far as a good reason for not to do it is given.}
+and at the same time introduces a "knowledge" for the macro name (defined using the directive "automatic in command").
+It sets the contexts such that \cs\cmdkl\ implements the code for using this "knowledge". It is somehow similar to:
+\begin{code}
+	\cs\newrobustcmd\cs\floor[1]\{\cs\kl[\cs\floor]\{\cs\lfloor\}\#1\cs\kl[\cs\floor]\{\cs\rfloor\}\}\\
+	\cs\knowledge\{\cs\floor\}\{"automatic in command"\}
+\end{code}\noindent
+but is shorter to write and also corrects some bugs of this direct implementation\footnote{For instance, with this wrong implementation, 
+	\smallcode{\cs\intro*\cs\floor\ x} would display in \cs\intro\ aspect the `\cs\lfloor'\ symbol but not the `\cs\rfloor' one.}.
+
+\AP As explained above, the \cs\knowledge\ command is implicit when defining such macros. The "knowledge" name is the macro name itself, and the directive used is ""automatic in command"".
+Hence, you can modify the behavior by redefining the directive:
+\begin{quote}	
+	\cs\knowledgedirective*\{"automatic in command"\}\{\dots\}
+\end{quote}
+
+
+\paragraph{Defining new commands}
+We have used \cs\knowledgenewrobustcmd\ in the above example.
+In fact, several commands are available for defining such knowledge-enhanced macros.
+Each of them corresponds to a normal command (from \LaTeX, or "xparse@@package", or "mathcommand@@package"), prefixed with `\texttt{knowledge}' or `\texttt{Knowledge}'.
+The behavior of these commands is identical to the original ones, and furthemore activates the ability to use \cs\cmdkl.
+(Note that it is forbidden for your macro to absorb anything more than the parameters described during its definition.)
+\AP
+The commands
+\begin{quote}
+	\csintro\knowledgerenewcommand,\\
+	\csintro\knowledgenewrobustcmd, and \\
+	\csintro\knowledgenewcommand\footnote{You should always prefer \cs\knowledgenewrobustcmd\ instead. It is just here for completeness.},
+\end{quote}
+correspond to \cs\newcommand, \cs\renewcommand, and \cs\newrobustcmd\ (from "etoolbox@@package") respectively.
+\AP 
+The commands
+\begin{quote}
+	\csintro\KnowledgeNewDocumentCommand, \\
+	\csintro\KnowledgeRenewDocumentCommand, \\ 
+	\csintro\KnowledgeProvideDocumentCommand, and \\
+	\csintro\KnowledgeDeclareDocumentCommand
+\end{quote}
+extend the corresponding commands from the "xparse@@package" package (it offers more complete possibilities to define the signature of macros, and do it in a cleaner and more systematic way).
+
+\AP Finally, the commands of the "mathcommand@@package" package (see~\Cref{subsubsection:mathcommand})
+are also extended (provided it has been loaded before the package "knowledge@@package"), yielding:
+\begin{quote}
+ \csintro\knowledgedeclarecommand,  \\
+ \csintro\knowledgenewmathcommand, \\
+ \csintro\knowledgenewtextcommand,  \\
+ \csintro\knowledgerenewmathcommand, \\

+\subsubsection{The combination \cs\withkl/\cs\cmdkl}
+\label{subsubsection:withkl}
+
+In fact, inside commands like~\cs\knowledgenewrobustcmd, the command~\cs\withkl\ is used.
+It has to be used in combination with \cs\cmdkl:
+\begin{center}
+	\smallcode{\csintro\withkl\{\cs\kl-like command\}\{\dots\csintro\cmdkl\{A\}\dots\csreintro\cmdkl\{B\}\dots\}}
+\end{center}
+Inside the right argument of \cs\withkl, \cs\cmdkl\ stands for a shorthand for the \cs\kl-like command, with the following specificities:
+the "modifiers@@variant" used before the \cs\withkl\ are absorbed and reinjected for each use of~\cs\cmdkl. Furthermore, all the uses of \cs\cmdkl, but the first one, get to be preceded of the \csintro\rekl* "modifier@@variant", which transformes in particular \cs\intro\ into \cs\reintro. Hence,
+\smallcode{\cs\intro*\cs\withkl\{\cs\kl[example]\}\{\dots\cs\cmdkl\{A\}\dots\cs\cmdkl\{B\}\dots\}}
+gets to be evaluated as
+\smallcode{\dots\cs\intro[example]\{A\}\dots\cs\reintro[example]\{B\}\dots}
+
+An example of use of this technique is if we want "knowledges" aware of the parameters of a macro.
+Imagine that you use the norms $1$ and $2$ of a function:
+\begin{code}
+\cs\newrobustcmd\cs\norm[2]\par
+	~~~~\{\cs\withkl\{\cs\kl[\cs\norm\{\#1\}]\}\{\cs\cmdkl\{\cs\|\}\#2\cs\cmdkl\{\cs\|\}\_\{\cs\cmdkl\{\#1\}\}\}\}\\
+\cs\knowledge\{\cs\norm\{1\}\}\{notion\}\\
+\cs\knowledge\{\cs\norm\{2\}\}\{notion\}
+\end{code}\noindent
+Now, the norm $1$ and the norm $2$ can be defined in different places since "knowledge" is specific to each case.
+\begin{code}
+   \cs\AP\ The norm~\$1\$ of a function~\$f\$ is denoted \$\cs\intro*\cs\norm1f\$.\\
+   {}[...]\\
+   \cs\AP\ The norm~\$2\$ of a function~\$f\$ is denoted \$\cs\intro*\cs\norm2f\$.\\
+   {}[...]\\
+   Here, \$\cs\norm 1g\$ and \$\cs\norm2h\$ link to the proper place, while\\\$\cs\norm3g\$ is an undefined knowledge.

+\subsubsection{Unexepected color in margin paragraph}
+This is a problem of the combination of the package "xcolor@@package" with \cs\marginpar: when a colored text gets to be broken into separated lines and the \cs\marginpar\ be inserted at this place, the colors leaks in to the margin text.
+It is independent of "knowledge@@package", but is more likely to occur when colors are often used.
+A correction is to force going the use of color black whenever inside a \cs\marginpar. For instance:
+\begin{code}
+\cs\let\cs\LaTeXmarginpar\cs\marginpar\\
+\cs\def\cs\marginpar\#1\{\cs\LaTeXmarginpar\{\cs\textcolor\{black\}\{\#1\}\}\}
+\end{code}

-% \subsubsection{Capturing subscripts, superscripts and primes}
-% We know provide the core code for parsing subscripts, superscripts and primes.
-%
-% The central command is  \csintro{\klparse_absorb_modifiers:}.
-% This command parses all the subscripts and so on occurring after,
-% and then launches \csintro{\klparse_absorb_modifiers_exec:}
-% (that is supposed to have been set with the proper code).
-% At the end, the token lists \csintro{\klparse_primes_tl}, \csintro{\klparse_subscript_tl}
-% and \csintro{\klparse_supscript_tl}
-% contain the texts that have been collected during the parsing. 
-% If a subscript or a superscript is not present, then the corresponding token list
-% is set equal to be \cs{\klparse_novalue_tl}. This is not the case for primes:
-% if there are no primes, then the token list \cs{\klparse_primes_tl} is simply empty.
-% Parsing subscripts, superscripts and primes can be deactivated or activated by setting appropriately the
-% macros \cs{\klparse_if_load_primes:TF}
-% \cs{\klparse_if_load_subscript:TF} and \cs{\klparse_if_load_supscript:TF}.
