 // When run with 2 or more arguments the file_poller tool will open a port on
 // the device, print it on its standard output and then start collect file
 // contents.  The first argument is the polling rate in Hz, and the following
 // arguments are file to poll.
 // When run with the port of an already running file_poller, the tool will
 // contact the first instance, retrieve the sample and print those on its
 // standard output. This will also terminate the first instance.
