We no longer use the span as the core type of tracing, instead that is an artifact of the exporter, and start and end tracing is just event based. This both makes the interface normalized, and also means the null exporter case is considerably cheaper in memory and cpu.

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.
