What a stupid project!
He encountered a problem: "Most of the low-cost web hosting companies do not provide SSH or git support, but only FTP." He then solved that problem and decided to make the work available to others.
But honestly, I also have a hard time finding a use case for this. The question I ask my self over and over again: why not mount an FTP share and point your origin to it? In fact I did something similar when I was still in university. My desktop computer had my central gip repo, I either pushed to it locally via the FS or remotely via SSH.
Anyways, good thing to have git over FTP but I predict that it will never get traction because it seems to be in part a reimplementation of git?! (At least that's what the github page suggests because every basic git cmd is explained but with some git-ftp prefix... ;))
