That would be difficult to do, at least for me. I do not know any way to interact with a website from a simple shell script, is this even possible? I was thinking more along the lines of wget but the links on the website are php and I don't know how to deal with those to get the relevant files.

I was thinking it would be a good Idea to have it pass all the same optional arguments on to flasher-3.5; as well as the interactive mode I mentioned above if no optional arguments are given.
