-This document was automatically generated by the {\em BNF-Converter}. It was generated together with the lexer, the parser, and the abstract syntax module, which guarantees that the document matches with the implementation of the language (provided no hand-hacking has taken place).
-
-\section*{The lexical structure of Core}
-
-\subsection*{Literals}
-String literals \nonterminal{String}\ have the form
-\terminal{"}$x$\terminal{"}, where $x$ is any sequence of any characters
-except \terminal{"}\ unless preceded by \verb6\6.
-
-
-Integer literals \nonterminal{Int}\ are nonempty sequences of digits.
-
-
-Double-precision float literals \nonterminal{Double}\ have the structure
-indicated by the regular expression $\nonterminal{digit}+ \mbox{{\it `.'}} \nonterminal{digit}+ (\mbox{{\it `e'}} \mbox{{\it `-'}}? \nonterminal{digit}+)?$ i.e.\
-two sequences of digits separated by a decimal point, optionally
-followed by an unsigned or negative exponent.
-
-
-
-
-
-TMeta literals are recognized by the regular expression
-\(\mbox{`?'} {\nonterminal{digit}}+\)
-
-CIdent literals are recognized by the regular expression
-\(({\nonterminal{letter}} \mid \mbox{`\_'}) ({\nonterminal{letter}} \mid {\nonterminal{digit}} \mid \mbox{`\_'} \mid \mbox{`''})*\)

-\subsection*{Reserved words and symbols}
-The set of reserved words is the set of terminals appearing in the grammar. Those reserved words that consist of non-letter characters are called symbols, and they are treated in a different way from those that are similar to identifiers. The lexer follows rules familiar from languages like Haskell, C, and Java, including longest match and spacing conventions.
-
-The reserved words used in Core are the following: \\
-
-\begin{tabular}{lll}
-{\reserved{Type}} &{\reserved{case}} &{\reserved{data}} \\
-{\reserved{in}} &{\reserved{let}} &{\reserved{of}} \\
-{\reserved{rec}} &{\reserved{sig}} &{\reserved{where}} \\
-\end{tabular}\\
-
-The symbols used in Core are the following: \\
-
-\begin{tabular}{lll}
-{\symb{;}} &{\symb{:}} &{\symb{\{}} \\
-{\symb{\}}} &{\symb{{$=$}}} &{\symb{(}} \\
-{\symb{)}} &{\symb{\_}} &{\symb{{$|$}}} \\
-{\symb{{$-$}{$>$}}} &{\symb{$\backslash$}} &{\symb{.}} \\
-\end{tabular}\\
-
-\subsection*{Comments}
-Single-line comments begin with {\symb{{$-$}{$-$}}}. \\Multiple-line comments are enclosed with {\symb{\{{$-$}}} and {\symb{{$-$}\}}}.
-
-\section*{The syntactic structure of Core}
-Non-terminals are enclosed between $\langle$ and $\rangle$.
-The symbols {\arrow} (production), {\delimit} (union)
-and {\emptyP} (empty rule) belong to the BNF notation.
-All other symbols are terminals.\\
