GitHead questions from the uninitiated

[Alan Milewczyk]

In the last week or so, I've been patching get_iplayer using GitHeadWin 
to make sure I'm using the latest version.

I presume GitHead is a way of advising interim patches prior to issuing 
an official update? But I'm puzzled, how do we know when this has been 
updated? It not like some file list where we can see the date stamp of 
the files.

Thanks
