[announce] Ethercat For Arduino

I announce an open source light ethercat stack for arduino.
available at git clone git://git.code.sf.net/p/ecslave/code

It is compatible with ethelab 1.5.1.

What is it ?
Can I see the source code in my browser ? or at least a webpage for it ?

Is there something to explain what this is that might help the uninitiated (me and others, I'm sure) figure out what this is? I am reluctant to download what appears may be some code without knowing what I'm getting. I wouldn't know what to do with it if I DID download it.
