Plugin for Gulp: css features for older browsers?

Question

css

There is a need to support ancient IE-shek (and other oldies) and a desire to shorten the process of writing css nonsense like this:

.class{
  //Текущий код
  opacity: 0.5;
  ms-filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=50);
  filter: alpha(opacity=50);

  //Желаемый код
  opacity: 0.5;
}

We need a gulp plugin that would substitute similar css features into the code when building the project. What do you advise? Is there something like this online?
