Publish website incl. submodules

Hello!

I'm quite, but not completely, new to Git. So far I've figured out everything I needed to know, but I just stumbled upon something which requires some help... I found the link to the mailinglist on https://git.wiki.kernel.org/index.php/GitCommunity

I want to use git to manage a (php-based) website. I'll be using "git submodules" to incorporate a few external tools. My question is: what's the best setup for publishing the latest version to the webserver, making sure even the submodules are updated to the correct version. I suppose I should use master-branch as the "latest version which to push", so the submodules should be updated to the version master is using.

Sincerely,
Marcus Gustafsson
