For anyone who has ever worked on a requirements document, you will know that version control is invaluable. For those of you who haven't here is a quick summary:

If you were making a list of things you want for some large or complex project, over time you will find somethings are unfeasible/too expensive/not important enough. But if it takes a long time to compile that list, someone new to the project might try to re-add those things or waste time talking about them. That is why system engineering is heavily reliant on version control. For example:

Things I want for the party:

1 - Food
2 - Beer
3 - Clown too expensive
4 3 - Music

So basically, in a review mode, you list EVERY item that was ever included even if it was removed AND you list a reason why it was removed. Pretty simple, right? Wouldn't it be great if the laws of the land were subject to the same type of review standards?
