It turns out, however, that these two functions are closely connected.
Record keeping became necessary because people wanted to compare a program's current state with how it was at some point in the past.
But before we do that, let's take a look at a mechanism that CVS doesn't provide (or at least, doesn't encourage): file locking.
If you've used other version control systems, you may be familiar with the lock-modify-unlock development model, wherein a developer first obtains exclusive write access (a lock) to the file to be edited, makes the changes, and then releases the lock to allow other developers access to the file.
Imagine how different the world would be if real books worked this way!Personally, I always use revision control on my coding projects now - it's saved me many times.To understand what this has to do with facilitating collaboration, we'll need to take a closer look at the mechanism that CVS provides to help numerous people work on the same project.This is like informing the library of what changes she made to the book and why.The library then incorporates these changes into a "master" copy, where they are recorded for all time.
