Google struggled to figure out a solution for managing software on the Mac platform and they came up with Simian. On Saturday, Google announced that Simian is now open source.
"Today we are open-sourcing Simian, our solution to enterprise-class Mac OS X package deployment," the announcement said. "Simian uses App Engine-based hosting to scale with the needs of your growing enterprise, and a Munki-based client which will continue to evolve through the outstanding work of Greg Neagle and the Munki community."
