The ci command is called from Continuous Integration scripts.
Usage: go run ci.go <command> <command flags/arguments>
Available commands are:
install [-arch architecture] [ packages... ] -- builds packages and executables
test [ -coverage ] [ -vet ] [ packages... ] -- runs the tests
archive [-arch architecture] [ -type zip|tar ] [ -signer key-envvar ] [ -upload dest ] -- archives build artefacts
importkeys -- imports signing keys from env
debsrc [ -signer key-id ] [ -upload dest ] -- creates a debian source package
nsis -- creates a Windows NSIS installer
xgo [ options ] -- cross builds according to options
For all commands, -n prevents execution of external programs (dry run mode).
