Serves as a reference harness to get benchmarking started.
Steps to run benchmark:
$ go test -run=^$ -bench=. -count=10
After you grab the output, put the various comparisons
into files before.txt and after.txt then edit those
result names to have a common name e.g.
s/BenchmarkLoggingNoExporter/BenchmarkIt/g
s/BenchmarkNoTracingNoMetricsNoLogging/BenchmarkIt/g
s/BenchmarkLoggingStdlib/BenchmarkIt/g
Now run benchstat:

Go Tools
This subrepository holds the source for various packages and tools that support the Go programming language.
Some of the tools, godoc and vet for example, are included in binary Go
distributions.
Others, including the Go guru and the test coverage tool, can be fetched with
go get.
Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
Download/Install
The easiest way to install is to run go get -u golang.org/x/tools/.... You can
also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
