Is it possible to configure the gem not to strip comments ?

1.9.3-p448 :001 > parser = CssParser::Parser.new
=>
1.9.3-p448 :002 > parser.add_block!("
1.9.3-p448 :003"> /* my css /
1.9.3-p448 :004"> body { / hello world */
1.9.3-p448 :005"> background: yellow;
1.9.3-p448 :006"> }")
=> nil
1.9.3-p448 :007 > parser.each_rule_set do |rs|
1.9.3-p448 :008 > puts rs
1.9.3-p448 :009?> end
body { background: yellow; }
=> [{:media_types=>[:all], :rules=>body { background: yellow; }}]
