Go dep - adding a fork via `source`. Useful when you want to use a private fork of a public repo for instance, without updating all package paths.

add.sh

SOURCE="github.com/you/thing"
FORK="github.com/other/thing"
PACKAGE="some-package"
CONSTRAINT="aabbcc"
dep ensure -add ${SOURCE}/${PACKAGE}:${FORK}.git@${CONSTRAINT}
