This is a fantastic creation! I'm using it right now on Tex Murphy: Overseer, and even though the download apparently keeps dying every 2 minute, the script beautifully picks up and resumes!
Hopefully, the end result won't be corrupted like the AIR Downloader tends to do with fragmented downloads... If it isn't then you are my new hero, sir! :D
unfortunately wget doesn't prevent from file corruption :( but there is a software (ccor) that can help you. follow the link in my first post...
