### push packages to a device

## usage: fx push-package [pkg1 pkg2 ...]
##
## Push packages to a device. One or more package names may be supplied. If no
## package name is suppled all packages in the build output will be pushed. The
## target must be reachable from the host and must already know how to reach
## the host package server (e.g. fx serve must be running).
##
## See https://fuchsia.googlesource.com/docs/+/master/development/workflows/package_update.md
## for more information about using this workflow.
