CVS is very simple and sophisticated version control. It’s is good version control system.

I use a Unix distribution with Virtual Box on windows and use CVS on that to back up my C code. So far, CVS and Git have been my primary choices. The reason why I prefer CVS is that it's less processor intensive and integrates easily into my Unix system. It also helps backup my code so that I can back to a previous built if an unexpected error occurs. Also, there is a large community of users and open source code too.

MATLAB functionality, GUI interface, powerful computing engine, and portability on different computing platforms - MacOS, Linux and Windows. The GUI interface that has been recently introduced is a welcome addition; the command line interface is available as well. Extensive online support and documentation. Hats off to the GNU community who volunteer to bring us superb software... for free!
