This is indeed sweet.

I created a fork and added similar SVN functionality too:

Nice. I usually just mirror svn repo's to git though :)

I had a dance with svn2git, trying to mirror this framework called Nooku Framework (not sure if you heard about it? ;) into a Git repo. Had a hard time trying to get tags, trunk and branches set up correctly. Somewhere in there I saw your name and "git submodule" appear in the activity stream, so I decided to try your script instead.

Yeah, svn2git only works if the svn repo has been fairly consistent with best practices throughout it's history...

As will other problems, it's hard to just leave them be :) Turns out it was just my skills that were a bit lacking. Got the branches and tags up and running now too, with correct authors as well :)

Great, now you can maintain your own fork of nooku on github and gradually replaces parts with http://bit.ly/zOg3Ov

Sounds like a great part-time activity! :)
I needs to learn me some more Symfony though. Haven't really touched it since Symfony 2 was in beta. What are you working with these days? Looks like a lot of it is about Symfony and Doctrine?

Added process forking for a 1000% speed increase (in a repo with about 25 deps)

About time I move this to a separate repo and refactor it for general prettiness.

Elegant! :)

So why use this script instead of git submodule?

(by elegant I of course mean quick+effective+pragmatic)

git submodules always cause problems in my experience. They confuse people who don't have a thorough understanding of git. And they're a bitch to remove. This script allows you to explicitly define what you want, at what version (be it commit, tag or branch) and where you want it. It's light, it's (as of today) fast, and everybody understands the deps.ini.
