+Interesting paths
+
+  In a large project, there can be 100's of millions of unique paths between a
+  very high level and a common low-level target. To make the output more useful
+  (and terminate in a reasonable time), GN will not revisit sub-paths
+  previously known to lead to the target.
+
+Options
+
+  --all
+     Prints all "interesting" paths found rather than just the first one.
+     Public paths will be printed first in order of increasing length, followed
+     by non-public paths in order of increasing length.
+
+  --public
+     Considers only public paths. Can't be used with --with-data.

+  --with-data
