+generates \textit{dot} graphs showing the dependencies between
+patches.\footnote{
+	Currently, \quilt{graph} only considers which files the
+	patches modify. Multiple patches may modify different areas
+	in the same file(s) without conflicting, in which case
+	\quilt{graph} would report false dependencies. It is
+	difficult to determine reliably whether or not two patches
+	have conflicts without actually applying the patches in
+	different orders.
