+#
+# cycles are flagged with `cycle {}` so we make the "cycle" red and the content
+# of the cycle yellow to make them easy to spot.
+#
+# the module starting with '::' are internal module that we don't really care
+# about (the subgraph is filtered by `--trim`)
+#
+# The "+" before module mark "direct" (vs "local") import and we don't really
+# care about that.
+#
+# We replace new lines by null bytes during process as it is easier to have sed
+# not do multiline work.
