+rendered this way; the program tries to emit useful warnings when it can't.
+
+The program can also produce a visualization of the resulting commit directed
+acyclic graph (DAG) in the input format of @uref{http://www.graphviz.org,
+Graphviz}.  The package also includes @command{cvssync}, a tool for mirroring
+masters from remote CVS hosts.")
