I’m considering he possibility of automating/scripting a basic WP install. Part of it will include downloading the latest WordPress version.
The en-us version can be obtained by downloading http://wordpress.org/latest.zip (or tar.gz), is there any way to get an always up-to-date file URL for other languages?
Can you include WP-CLI in your script? Then it could be as easy as:
