Random observation -- what's up with almost 20 of the 24 'contributors' to this project mostly having made 1 edit changes to the README? Is this some kind of pervasive Github resume padding scheme that I'm just now picking up on? (it will show the repo in the "Repositories contributed to" section of your profile even for just those 1-line README edits)
