The ci command is called from Continuous Integration scripts.
Usage: go run build/ci.go <command> <command flags/arguments>
Available commands are:
install [ -arch architecture ] [ -cc compiler ] [ packages... ] -- builds packages and executables
test [ -coverage ] [ packages... ] -- runs the tests
lint -- runs certain pre-selected linters
importkeys -- imports signing keys from env
xgo [ -alltools ] [ options ] -- cross builds according to options
For all commands, -n prevents execution of external programs (dry run mode).
