.Sh DESCRIPTION
The
.Nm bcd ,
.Nm ppt
and
.Nm morse
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.
.Pp
Available options:
.Bl -tag -width flag
.It Fl s
The
.Fl s
option for
.Nm morse
produces dots and dashes rather than words.
.It Fl d
The
.Fl d
option for
.Nm morse
decodes dot-dash morse (as generated by using the
.Fl s
option) back into text.  A lowercase
.Sq x
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
.Sq --
to keep it from being mistaken for options.
