#   invalidates built objects and it's annoying to wait if all is recompiled

%description
mod_pagespeed automates the application of those rules in an Apache
server. HTML, CSS, JavaScript, and images are changed dynamically
during the web serving process, so that the best practices recommended
by Page Speed can be used without having to change the way the web
site is maintained.
