Countless times I have bought a CD and ripped it to my music collection only to find that it has no meta data. No artist, no album and worst off all no album art (I like my album art alright). There are countless tools out there that could do this for me but I wanted one that I had made because why not?
The optparse module is a great way for you to add some command line arguments to your python scripts. It has an easy syntax, inbuilt help option and loads of customization to your program.
