 4.4 Undoing A Change
 ====================
 
 Should you need to undo a change that you have not yet committed (so
 that you can start over), you can do so on per-file basis by simply
 checking out the file again:
 
      git checkout awkgram.y      Undo changes to awkgram.y. There is no output
 
    To start over completely, use 'git reset --hard'.  Note that this
 will _throw away_ all your changes, with no chance for recovery, so be
 sure you really want to do it.
