Deplist lists the dependencies of a Go package. (You can almost use go list
for this, but excluding stdlib packages, which deplist does by default, is
trickier.)
Examples:
$ deplist github.com/jmoiron/sqlx
github.com/jmoiron/sqlx/reflectx
$ deplist -t github.com/jmoiron/sqlx # -t to show test dependencies
github.com/go-sql-driver/mysql
github.com/jmoiron/sqlx/reflectx
github.com/lib/pq
github.com/lib/pq/oid
github.com/lib/pq/scram
github.com/mattn/go-sqlite3
deplist -h shows usage info.
