 |================================
 
 You may be wondering what the difference is between _author_ and _committer_.
 The author is the person who originally wrote the work, whereas the committer is the person who last applied the work.
 So, if you send in a patch to a project and one of the core members applies the patch, both of you get credit -- you as the author, and the core member as the committer.
 We'll cover this distinction a bit more in <<ch05-distributed-git#ch05-distributed-git>>.
