# Importing a platform CLI must only build its command tree: the console
# scripts import it before Click can answer a shell completion request, which
# the completion scripts make on every keystroke. Every command imports what
# it runs when it is invoked. Each of these costs tens of milliseconds to
# import and is the sign that a command implementation is imported too early.
