+
+Have you ever:
+
+    Made a change to code, realised it was a mistake and wanted to revert back?
+    Lost code or had a backup that was too old?
+    Had to maintain multiple versions of a product?
+    Wanted to see the difference between two (or more) versions of your code?
+    Wanted to prove that a particular change broke or fixed a piece of code?
+    Wanted to review the history of some code?
+    Wanted to submit a change to someone else's code?
+    Wanted to share your code, or let other people work on your code?
+    Wanted to see how much work is being done, and where, when and by whom?
+    Wanted to experiment with a new feature without interfering with working code?
+
+In these cases, and no doubt others, a version control system should make your life easier.
+
+To misquote a friend: A civilised tool for a civilised age.
