+      DAG
+          The repository of changesets of a distributed version control system
+          (DVCS) can be described as a directed acyclic graph (DAG), consisting
+          of nodes and edges, where nodes correspond to changesets and edges
+          imply a parent -> child relation. This graph can be visualized by
+          graphical tools such as "hg log --graph". In Mercurial, the DAG is
+          limited by the requirement for children to have at most two parents.
