+(* This signature defines the lexical tokens for LIGO
+
+   _Tokens_ are the abstract units which are used by the parser to
+   build the abstract syntax tree (AST), in other words, the stream of
+   tokens is the minimal model of the input program, carrying
+   implicitly all its structure in a linear encoding, and nothing
+   else, in particular, comments and whitespace are absent.
+
+     A _lexeme_ is a specific character string (concrete
+   representation) denoting a token (abstract representation). Tokens
+   can be thought of as sets, and lexemes as elements of those sets --
+   there is often an infinite number of lexemes, but a small number of
+   tokens. (Think of identifiers as lexemes and one token.)
+
+     The tokens are qualified here as being "lexical" because the
+   parser generator Menhir expects to define them, in which context
+   they are called "parsing tokens", and they are made to match each
+   other. (This is an idiosyncratic terminology.)
+
+     The type of the lexical tokens is the variant [t], also
+   aliased to [token].
