detecting css transition support with modernizr

I'm going to use css transition and a jquery plugin as fallback for browsers that don't support it. I want to use modernizr to detect css transition support. It's overkill to load entire library for this, i only want to grab the portion of code i need to detect css transition. in the download page of modernizr there are a lot of options and extras which confuse me. My question is what options should i select to efficiently detect css transition?

<script type="text/javascript">
// modernizr
</script>


<script type="text/javascript">
    if(!Modernizr.csstransitions) { 
     // Use jquery if CSS transitions are not supported
    }
</script>
