its not just the vcs system. git is based on the principal of social coding. sharing code with others, forking other peoples code to fit your needs and sending modifications back to them. i cant think of a better addition to the ci community.
EllisLab has always said that if you fix a problem and submit the code yourself that it can get added to the main repo much much quicker… this also enables others to tinker around with the core to do interesting things…and then share that code with the community in a very easy and interactive way
The Bug Report section in this forum is quite good and also generates solutions that other coders have discovered.
I am not familiar with the GIT system but CI’s core is supplied and numerous coders supply alternative MY_Libraries.php.
Also the WIKI is abound with additional code, solutions and libraries.
Has the GIT that much more going for it?
