Maybe someone knows how i could update my live sites theme from a version control*) project repository.
Point is that it's really time consuming if you got your theme hosted with version control (as an open source project), have a live site that uses the theme and maybe also make it available else where. Normally that means half an hour until you got everything running after you wrote an update/commited something.
I've seen it once that a server got a "live" update via a git project, but so far couldn't find out how this would be done.
Nice would be if there's a plugin out there that does this already. Libraries or similar are also ok.
*) The Q is about Github, Bitbucket, etc. and it also doesn't matter if the solution is git or svn based.
