%description
Apache Aurora is a service scheduler that runs on top of Mesos, enabling you to schedule
long-running services that take advantage of Mesos' scalability, fault-tolerance, and
resource isolation.

%description thermos
Thermos a simple process management framework used for orchestrating dependent processes
within a single Mesos chroot.  It works in tandem with Aurora to ensure that tasks
scheduled by it are properly executed on Mesos slaves and provides a Web UI to monitor the
state of all running tasks.
