First Look at Mercurial
By pelegri on Aug 25, 2006
I found Neuron's latest blog on Mercurial interesting so I'll pass it on, with caveats. As you may have read, one of the key questions in the OpenSolaris community has been what Source Control System to use. There are Many Options to choose from, but the OpenSolaris team decided to Explore Two Options: Subversion for centralized cases, and Mercurial for distributed.
So, with the caveat that GlassFish has no current plans to use Mercurial (we have other fish to fry) and that I really don't know what other projects at Sun will do, check out Neuron's Overview of Mercurial.
