Anyone know of a script (php, python, perl, bash, whatever) that will convert a stylesheet from px to em?

Like, it would take input of the filename and base font-size (default 16) and convert all px instances to em?

eg:

convertpx2ems --file stylesheet.css --base-font-size 16

would convert this:

button { font-size:14px; padding:8px 19px 9px; }

to something like this:

button { font-size: .875em; padding: .5em 1.188em .563em; }

...maybe, is there a way to do this with sass?
