-This script implements the `mach devtools-css-db` command. It runs the C preprocessor
-on the CSS properties header file to get the list of preferences associated with
-a specific property, and it runs an xpcshell script that uses inIDOMUtils to query
-the CSS properties used by the browser. This information is used to generate the
-properties-db.js file.
