In other words, git's data structure can be thought of as a tree of commits of a tree of files. So, HEAD is a tree of (committed) files, Index is a tree of (about to be committed) files, and working is a tree of not committed files. And, HEAD has a tree of history of changes. --- Entertaining minecraft videos http://YouTube.com/keybounce -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.
