thanks, but I'm still far away from understanding

can you give me some pointer/keyword which can help me understanding the 
following regexp (in particular, I can't understand (=*) and @{1})?

environment comment delim `--\[(=*)\[` "]" + @{1} + "]" multiline nested 
begin
  include "url.lang"
  environment comment delim "[[" "]]" multiline nested begin
        include "url.lang"
  end
end
