+\section{Meta notations used in this document}
+
+Non-terminals are printed between angle brackets (e.g. $\NT{non-terminal}$) and
+terminal symbols are printed in bold font (e.g. $\ETERM{terminal}$). Lexemes
+are displayed as non-terminals.
+
+The usual operators on regular expressions:
+\begin{center}
+\begin{tabular}{l|l}
+\hfil notation & \hfil meaning \\
+\hline
+$\STAR{regexp}$ & repeat $regexp$ 0 or more times \\
+$\PLUS{regexp}$ & repeat $regexp$ 1 or more times \\
+$\OPT{regexp}$ & $regexp$ is optional \\
+$regexp_1~\mid~regexp_2$ & alternative
+\end{tabular}
+\end{center}
+
+Parenthesis are used to group regexps. Beware to distinguish this operator
+$\GR{~}$ from the terminals $\ETERM{( )}$, and $\mid$ from terminal
+\TERMbar.
+
+Rules are optionaly annotated in the right margin with:
+\begin{itemize}
+\item a precedence and associativity (L for left, R for right and N for no associativity), indicating how to solve conflicts;
+ lower levels are tighter;
+\item a rule name.
+\end{itemize}
+In order to solve some conflicts, a non-terminal may be invoked with a
+precedence (notation: $\NTL{entry}{prec}$), meaning that rules with higher
+precedence do not apply.
+
+\section{Lexical conventions}
+
+Lexical categories are:
+\begin{rules}
+\DEFNT{ident}
+ \STARGR{\NT{letter}\mid\CHAR{_}}
+ \STARGR{\NT{letter}\mid \NT{digit} \mid \CHAR{'} \mid \CHAR{_}}
+\SEPDEF

+ \mid\NT{unicode-letter}
+
+\SEPDEF
+\DEFNT{string} \CHAR{"}~\STARGR{\CHAR{""}\mid\NT{unicode-char-but-"}}~\CHAR{"}
+\end{rules}
+
+Reserved identifiers for the core syntax are:
+\begin{quote}
+\KWD{as},
+\KWD{cofix},
+\KWD{else},
+\KWD{end},
+\KWD{fix},
+\KWD{for},
+\KWD{forall},

+\KWD{match},
+\KWD{Prop},
+\KWD{return},
+\KWD{Set},
+\KWD{then},
+\KWD{Type},
+\KWD{with}
+\end{quote}
+
+Symbols used in the core syntax:
+$$ \KWD{(}
+~~ \KWD{)}
+~~ \KWD{\{}
+~~ \KWD{\}}
+~~ \KWD{:}
+~~ \KWD{,}
+~~ \Rightarrow
+~~ \rightarrow
+~~ \KWD{:=}
+~~ \KWD{_}
+~~ \TERMbar
+~~ \KWD{@}
+~~ \KWD{\%}
+~~ \KWD{.(}
+$$
+
+Note that \TERM{struct} is not a reserved identifier.
+
+\section{Syntax of terms}
+
+\subsection{Core syntax}
+
+The main entry point of the term grammar is $\NTL{constr}{9}$. When no
+conflict can appear, $\NTL{constr}{200}$ is also used as entry point.
