+# All +x files in /usr/lib/network/hooks will be sourced when this file is.
+# Hook files can override any of the utility functions defined here for custom
+# behavior (such as logging error messages to syslog). This lets us keep netcfg
+# simple but gives it the flexibility for users to make modular use of it to do
+# more complex things
