I've attached an updated patch with the modifications suggested so far:

 - Changed license from expat to public-domain
 - Changed "No tests" to lowercase "no tests"
 - Added "no configure file" comment
 - Install Readme files

I indent the package definition in emacs by marking the package definition (CTRL+Space) and running `M-x indent-region`, I'm not sure what indentation was wrong with the original patch I submitted, but I ran indent-region on it again anyway.
