// Package glog exposes an API subset of the [glog](https://github.com/golang/glog) package.
// All logging state delivered to this package is shunted to the global [klog logger](ttps://github.com/kubernetes/klog).
//
// We depend on some downstream components that use glog for logging. This package makes it so we can intercept
// the calls to glog and redirect them to klog and thus produce a consistent log for our processes.
