Question about the Roll20 API Script Library

Is there a way that I am missing, to see what scripts that you may add through the Script Library actually do? I am looking for a "less-brief" description but in many cases I only see something like the following. Does this simply calculate double damage? I don't know since it doesn't say... Critical Version: 0.1.0 Authors: Ryan Jentzsch Critical hit generator. Use !critical [percent] to use. Thank you!
