The

commands read the given input and reformat it in the form of
punched cards, paper tape, or morse code, respectively.
Acceptable input are command line arguments or the standard input.

.Bl -tag -width flag
.It Fl s
The
.Fl s
option for
.Nm morse
produces dots and dashes rather than words.

The
.Fl d
option for

decodes dot-dash morse (as generated by using the

option) back into text.  A lowercase

is printed for undecipherable input; otherwise, text is returned uppercase.
If the morse to be translated is given on the command line, it should be
preceded by

to keep it from being mistaken for options.
