NAME

       go - tool for managing Go source code

DESCRIPTION

       The  Go  path  is used to resolve import statements.  It is implemented by and documented in the go/build
       package.

       The GOPATH environment variable lists places to look for Go  code.   On  Unix,  the  value  is  a  colon-
       separated  string.   On  Windows,  the  value is a semicolon-separated string.  On Plan 9, the value is a
       list.

       GOPATH must be set to build and install packages outside the standard Go tree.

       Each directory listed in GOPATH must have a prescribed structure:

       The src/ directory holds source code.  The path below 'src' determines  the  import  path  or  executable
       name.

       The  pkg/ directory holds installed package objects.  As in the Go tree, each target operating system and
       architecture pair has its own subdirectory of pkg (pkg/GOOS_GOARCH).

       If DIR is a directory listed in the GOPATH, a package with source in DIR/src/foo/bar can be  imported  as
       "foo/bar" and has its compiled form installed to "DIR/pkg/GOOS_GOARCH/foo/bar.a".

       The bin/ directory holds compiled commands.  Each command is named for its source directory, but only the
       final  element,  not  the entire path.  That is, the command with source in DIR/src/foo/quux is installed
       into DIR/bin/quux, not DIR/bin/foo/quux.  The foo/ is stripped so that you can add DIR/bin to  your  PATH
       to  get  at  the installed commands.  If the GOBIN environment variable is set, commands are installed to
       the directory it names instead of DIR/bin.

       Here's an example directory layout:

           GOPATH=/home/user/gocode

           /home/user/gocode/
               src/
                   foo/
                       bar/               (go code in package bar)
                           x.go
                       quux/              (go code in package main)
                           y.go
               bin/
                   quux                   (installed command)
               pkg/
                   linux_amd64/
                       foo/
                           bar.a          (installed package object)

       Go searches each directory listed in GOPATH to find source code, but new packages are  always  downloaded
       into the first directory in the list.
