2. Revision Control: What?
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.

GIT can save periodic snapshots of your code (commits)
All past commits are stored and can be easily reintegrated.
