This program sends morse code using the buzzer on your Apollo node.

Usage:  morse [ -s <speed> ] [ -v ] [ -i ] [ -t ] <arguments> ...

The '-s' option takes a decimal number as an argument and sets the sending
speed in words per minute.

The '-v' option prints the output to standard out as dots (.) and dashes (-).

The '-i' option takes input from standard input instead of from the
command line.

The '-t' option is used to check timing.
