### listen for kernel logs
## usage: fx klog [--raw] [-r | --remote-symbols]
##
## --raw do not attempt to symbolize the log
##
## --remote-symbols|-r attempt to resolve symbols using predefined remote
## symbol servers for symbols that cannot be resolved
## locally. See `fx help symbolize` for more
## information on remote symbol servers.
##
## This command delegates to the Zircon `loglistener` binary.
## It will listen to the device specified with `fx -d DEVICE klog` or
## `fx set-device`, otherwise one of the devices on the link-local network.
