This file is intended to be used as a standin for a klog'ed executable.
|
|
|
|
It is called by the integration test via `go run` and with different klog
|
|
flags to assert on klog behaviour, especially where klog logs its output
|
|
when different combinations of the klog flags are at play.
|
|
|
|
This file is not intended to be used outside of the integration tests and
|
|
is not supposed to be a (good) example on how to use klog.
