%Rules
--------------------- Rules for Scanned Tokens --------------------------------
-- The lexer creates an array list of tokens which is defined in the PrsStream class.
-- A token has three attributes: a start offset, an end offset and a kind.
--
-- Only rules that produce complete tokens have actions to create token objects.
-- When making a token, calls to the methods, $getToken(1) and $getRightSpan(),
-- provide the offsets (i.e. the span) of a rule's right hand side (rhs) and thus of the token.
-- For a rule of the form A ::= A1 A2 ... An, the start offset of the rhs of A is given by
-- $getToken(1) or by $getLeftSpan() and the end offset by $getRightSpan().
--
-- Regarding rules for parsing in general, note that for a rhs symbol Ai, the
-- method $getToken(i) returns the location of the leftmost character derived from Ai.
-- The method $getLeftSpan(i) returns the same location unless Ai produces %empty in which case
-- it returns the location of the last character derived before reducing Ai to %empty.
-- The method $getRightSpan(i) returns the location of the rightmost character derived from Ai
-- unless Ai produces %empty in which case it returns the location of the last character
-- derived before reducing Ai to %empty.
