Revision Control: What? Revision (or version) control systems are software
aimed at managing changes to documents (text files).
Famous version control software: TRADITIONAL: CVS, SVN;
MODERN: Bazaar, Mercurial, GIT.
Throughout the whole course GIT will be: Your precious ally in developing your project code.
The default tool for the submission of your research proposal and the final submission of all the project files.

Revision Control: Why? Because the human brain was not initially created for
programming...
