## GO15VENDOREXPERIMENT
As of [June 19th, 2015](https://groups.google.com/d/msg/golang-dev/74zjMON9glU/EOKSoaL5p8wJ), the Go toolchain includes an experimental vendoring flag, `GO15VENDOREXPERIMENT`. This is now part of the Go 1.5 release and represents the Go team's recommended approach to vendoring dependencies. You can read more about how this environment variable works in the [Go 1.5 documentation](https://golang.org/cmd/go/#hdr-Vendor_Directories) and the [original design document](https://docs.google.com/document/d/1Bz5-UB7g2uPBdOx-rw5t9MxJwkfpx90cqG9AFL0JAYo/view).
