    use strict;
    use warnings FATAL => 'all';
    use MarpaX::Languages::ECMAScript::AST::Grammar::ECMAScript_262_5::Lexical::RegularExpressionLiteral;

=head1 DESCRIPTION

This modules describes the ECMAScript 262, Edition 5 regular expression literal grammar written in Marpa BNF, as of L<http://www.ecma-international.org/publications/standards/Ecma-262.htm>.

This module inherits the methods from MarpaX::Languages::ECMAScript::AST::Grammar::ECMAScript_262_5::Base package.

=head1 SUBROUTINES/METHODS

=head2 make_grammar_content($class)

Returns the grammar. This will be injected in the Program's grammar.
