Hopefully you can use or learn from them. It should be noted that while they are executing, your machine might take a bit of strain - so it might not be a good idea to leave them running indefinately. There may also be bits of code lying about that do nothing - try to ignore them, they're merely bits that I added while hacking about with the script and overlooked during the cleanup. There is none - the scripts are not copyright. However, you may not charge for any works derived from these scripts or works that contain them - either partially or in their entirity.
Due credit is appreciated.
