With all these distributed revision control systems now available (bzr, hg, darcs, svk, many more), I find I need an introduction to the concepts and advantages of repository distribution. It seems to me that it has the potential for leading to anarchy, though I can see how some things would be improved (working offline, maintaining local patches). It's not obvious how I push changes back upstream. Can someone point me to some useful content (web pages or books) which will help me wrap my brain around the ideas? Maybe a compare/contrast of the major players?
Thanks,
