 How to test this:

 '''Prerequisites:''' [http://nodejs.org/ nodejs]  and [http://gruntjs.com
 /getting-started grunt]

 {{{

 $ mkdir rtltest
 $ cd rtltest
 $ svn co http://develop.svn.wordpress.org/trunk .
 $ wget http://core.trac.wordpress.org/raw-
 attachment/ticket/24977/24977.gruntfile.diff
 $ patch -p0 -i 24977.gruntfile.diff
 $ npm install https://github.com/yoavf/grunt-
 cssjanus/archive/master.tar.gz
 $ npm install (for other deps)
 $ cd src
 $ rm wp-includes/css/*-rtl.css
 $ rm wp-admin/css/*-rtl.css
 $ wget http://core.trac.wordpress.org/raw-
 attachment/ticket/24977/24977.change_rtl_loading.diff
 $ patch -p0 -i 24977.change_rtl_loading.diff
 $ cd ..
 $ grunt build
 }}}

 a {{{build}}} directory will be created. It contains a clean WP core
 build, with the following changes applied:
 1. Existing manually created rtl css files removed
 1. Auto generated RTL css files added
 1. Core RTL css files will be loaded instead of LTR css files (as defined
 by the {{{wp_default_styles()}}} function, if the text direction is RTL

 If you'd like to quickly test this build directory in RTL mode, you can
 use the [wordpress.org/plugins/rtl-tester/ RTL Tester] plugin
 As you'll quickly see, everything looks mostly OK - magic! However, there
 are a bunch of issues with how the admin looks in this case - in most
 cases related to sprites.

 This is one of things to do next - each existing LTR css file needs to be
 audited to make sure sprites are used properly. In some cases, we might
 want to patch cssjanus itself if it isn't doing it's job properly.
