Check out git-describe.

For example, from my git respository:

$ git-describe

This is made of three parts:

 v1.5.2-rc3  = most recent annotated tag from current HEAD
 29          = number of commits on this branch since that tag
 gd7d7255    = "g" then first 7 hex digits of current HEAD's hash

When HEAD is at a tag, git-describe returns only the tag, so if you've just 
tagged a release (for example), then you compile that version, you would not 
get the second two fields.

This string is a reasonably human readable globally unique identifier for a 
particular revision.
