How to Expand and Add Your Own
This system is cool, in that it isn't difficult to make, and is pretty much as "cookie cutter" as you can get. What one script does is pretty much the same for every other, other than the different reference file and variable.
So, this means you can make your own randomized answers. All you have to do is make a text file in that same folder you downloaded(after extraction) and enter as many different responses as you want. Then copy one of the example scripts, change the file location to that of the file you just made, and change the variable to something unique and not yet used.
