+Leveled execution logs for Go.
+
+This is an efficient pure Go implementation of leveled logs in the
+manner of the open source C++ package
+ https://github.com/google/glog
+
+By binding methods to booleans it is possible to use the log package
+without paying the expense of evaluating the arguments to the log.
+Through the -vmodule flag, the package also provides fine-grained
+control over logging at the file level.
+
+The comment from glog.go introduces the ideas:
+
+ Package glog implements logging analogous to the Google-internal
+ C++ INFO/ERROR/V setup. It provides functions Info, Warning,
+ Error, Fatal, plus formatting variants such as Infof. It
+ also provides V-style logging controlled by the -v and
+ -vmodule=file=2 flags.
+
+ Basic examples:
+
+ glog.Info("Prepare to repel boarders")
+
+ glog.Fatalf("Initialization failed: %s", err)
+
+ See the documentation for the V function for an explanation
+ of these examples:
+
+ if glog.V(2) {
+ glog.Info("Starting transaction...")
+ }
+
+ glog.V(2).Infoln("Processed", nItems, "elements")
+
+
+The repository contains an open source version of the log package
+used inside Google. The master copy of the source lives inside
+Google, not here. The code in this repo is for export only and is not itself
+under development. Feature requests will be ignored.
