-This script assumes that is is run from the root of your Go package (for
-example, "/go/src/app" if your GOPATH is set to "/go").
-
-In Go 1.4, a feature was introduced to supply the canonical "import path" for a
-given package in a comment attached to a package statement
-(https://golang.org/s/go14customimport).
-
-This script allows us to take a generic directory of Go source files such as
-"/go/src/app" and determine that the canonical "import path" of where that code
-expects to live and reference itself is "github.com/jsmith/my-cool-app".  It
-will then ensure that "/go/src/github.com/jsmith/my-cool-app" is a symlink to
-"/go/src/app", which allows us to build and run it under the proper package
-name.
-
-For compatibility with versions of Go older than 1.4, the "import path" may also
-be placed in a file named ".godir".
-
-Available Commands:
-
-  $base download
-  $base download -u
-    (equivalent to "go get -d [args] [godir]")
-
-  $base install
-  $base install -race
-    (equivalent to "go install [args] [godir]")
-
-  $base run
-  $base run -app -specific -arguments
-    (assumes "GOPATH/bin" is in "PATH")
