Fedora Reaching Out to New Niches
"Purpose-built Fedora distributions, called 'spins', are a recent addition to that community in an attempt to reach additional users. The idea is to use tools like Revisor to create a custom collection of software that work well together for a particular set of tasks. This collection can then be installed or run from a live CD, providing an easy means to have the right collection of tools immediately, rather than after a lengthy yum install pass."
