If you follow Rails tradition and name your SASS files foo.css.sass, you may have noticed some deprecation warnings on compilation after upgrading sass-rails.
The extra .css has been deprecated and won't be supported in future versions of Sprockets.
Random? Maybe. Worth crying about? Nah. Here's a bash script to handle the otherwise painful rename.
for file in $(find ./app/assets/stylesheets/ -name "*.css.sass")
git mv $file `echo $file | sed s/\.css//`
