+Since 3.2.1, the tool also supports the `-i` or `--ignore-unresolved` flag.
+Use these flags when you have typehints to classes that cannot be resolved.
+When you omit the flag, such classes will cause the tool to fail with an
+exception message. By adding the flag, you can have it continue and produce
+configuration. This option is particularly useful when typehints are on
+interfaces or resolve to services served by other abstract factories.
