+				kind of version control system which allows not only workflow with one central server
+				but also decentralized workflows where changesets are pushed or pulled between particular nodes;
+				each node has typically full repository clone with all the history (commits, branches, tags);
+				this facilitates offline work –
+					developer can do commits or work with branches and tags even if he is offline –
+					and after going online,
+						he pushed his work to other developers
+						or to the central repository
+						or his work is pulled by others;
+				other advantage is easy backup – just clone the repository and then do push/pull from the working one;
+				Examples of DVCS: Mercurial (Hg), Git, Bazaar (bzr), Monotone (mtn), Fossil, GNU arch, Darcs, DCVS or SVK
