This ASSUMES you want the whole of (binary1) string replacing.

NAME

       morsegen - convert file to ASCII morse code

SYNOPSIS

	 morsegen <file>

DESCRIPTION

       This program implements the International Morse Code Standard by converting ASCII text file into morse code ASCII notation.

       Morse code was created for the telegraph in the early 1840s. Morse code uses a standardized sequence of short and long elements to
       represent the letters, numerals, punctuation and special characters of a given message.

       The morse code standard does not define all characters in ASCII table therefore translation of file into morse notation is only an
       approximation. The following special translation have been used:

	   ASCII	   Morse prosign
	   ------------    ------------------
	   ' ' (space)	   Invitation to transmit
	   			   Starting signal
	   
		   Wait
	   
		   End of work

OPTIONS

       None.

ENVIRONMENT

       None.

FILES

       None.

SEE ALSO

AUTHORS

       Program was written by Luigiru Auriemma <aluigi@autistici.org>.

       This manual page was written by Jari Aalto <jari.aalto@cante.net> for the Debian GNU system (but may be used by others). Released under
