I extract the parser from RDoc, and modify it.
I use this parser in order to display the structure of the 
Ruby script(Module/Class/Method).
Though I don't know this parser is good or simple,
I hope this is userful. You can get it at

   http://jurader.s1.xrea.com/archive/browser.tar.gz

There are some tests in this archive. But no documentation.
This is the sample script.  

------------- Sample ---------------
exit if ARGV.size == 0

require 'parser/parser'
#require 'pp'                          
  
parser = FreeRIDE::Parser.new    
io = File.open(ARGV[0])

begin 
  parser.scan(io)
  #pp parser.top_level
  p parser.top_level
  ensure
    io.close
  end 
end
