get

var CmdGet = &base.Command{
	UsageLine: "get [-d] [-f] [-fix] [-insecure] [-t] [-u] [build flags] [packages]",
	Short:     "download and install packages and dependencies",
	Long: `
Get downloads the packages named by the import paths, along with their
dependencies. It then installs the named packages, like 'go install'.
The -d flag instructs get to stop after downloading the packages; that is,
it instructs get not to install the packages.
The -f flag, valid only when -u is set, forces get -u not to verify that
each package has been checked out from the source control repository
implied by its import path. This can be useful if the source is a local fork
of the original.
The -fix flag instructs get to run the fix tool on the downloaded packages
before resolving dependencies or building the code.
The -insecure flag permits fetching from repositories and resolving
custom domains using insecure schemes such as HTTP. Use with caution.
The -t flag instructs get to also download the packages required to build
the tests for the specified packages.
The -u flag instructs get to use the network to update the named packages
and their dependencies.  By default, get uses the network to check out
missing packages but does not use it to look for updates to existing packages.
The -v flag enables verbose progress and debug output.
Get also accepts build flags to control the installation. See 'go help build'.
When checking out a new package, get creates the target directory
GOPATH/src/<import-path>. If the GOPATH contains multiple entries,
get uses the first one. For more details see: 'go help gopath'.
When checking out or updating a package, get looks for a branch or tag
that matches the locally installed version of Go. The most important
rule is that if the local installation is running version "go1", get
searches for a branch or tag named "go1". If no such version exists it
retrieves the most recent version of the package.
When go get checks out or updates a Git repository,
it also updates any git submodules referenced by the repository.
Get never checks out or updates code stored in vendor directories.
For more about specifying packages, see 'go help packages'.
For more about how 'go get' finds source code to
download, see 'go help importpath'.
