### Run various checks to determine the health of a Fuchsia checkout.

## usage: fx doctor

# The goal of this script is to detect common issues with a Fuchsia
# checkout. For example, on OS X the xcode command line tool
# installation often lapses. Ensuring that `xcode select --install` is
# run as part of a checkout or build is problematic: the step involves
# manual input. Detecting that it needs to be run, however, is
# perfectly mechanizable.
