The need to manage changes is absolutely intrinsic to evolution.
Fortunately, there are tools to help with the challenge.
The two most traditional and famous tools are:
There are others as well, such as:
Fortunately, both Solaris 11 and Oracle Solaris Studio support Mercurial.
Actually, they support the more traditional CVS and SVN too.
I have started with Mercurial by listening to others' experience.
Then I've managed to learn a little more from a main reference:

But the great news is that Mercurial is quite simple and effective.
A Revision Control System (RCS) is also know as a:
