IUS Repo

I ran across this while looking for a way to get a current version of PHP on a CentOS 7 machine.  It seems the guys at Rackspace are maintaining  their IUS (Inline with Upstream Stable) repository that provides the “latest upstream versions of PHP, Python, MySQL”.  It also seems like the CentOS folk suggest it plays nicely with EPEL.  This should be handy with Slim webapps.
