I did that! I hope you are not the person who suffered that from me (did you use Picnic CSS a few years back?). So for a newer project I put some setup code that will look for all code snippets with a specific comment and run that with the code after the comment. For generating the website documentation that test bit can be stripped (though I kept it for now).
