def code_block( name, arguments, options, content, lineno,
             content_offset, block_text, state, state_machine ):
  The code-block directive provides syntax highlighting for blocks
  of code.  It is used with the the following syntax::
  .. code-block:: CPP
    #include <iostream>
    int main( int argc, char* argv[] )
      std::cout << "Hello world" << std::endl;
  The directive requires the name of a language supported by SilverCity
  as its only argument.  All code in the indented block following
  the directive will be colourized.  Note that this directive is only
  supported for HTML writers.
  language = arguments[0]
    module = getattr(SilverCity, language)
    generator = getattr(module, language+"HTMLGenerator")
  except AttributeError:
    error = state_machine.reporter.error( "No SilverCity lexer found "
      "for language '%s'." % language, 
      docutils.nodes.literal_block(block_text, block_text), line=lineno )
    return [error]
  io = StringIO.StringIO()
  generator().generate_html( io, '\n'.join(content) )
  html = '<div class="code-block">\n%s\n</div>\n' % io.getvalue()
  raw = docutils.nodes.raw('',html, format = 'html')
  return [raw]

code_block.arguments = (1,0,0)
code_block.options = {'language' : docutils.parsers.rst.directives.unchanged }
