NAME
       cwgen - generate groups of random characters for Morse code practice

SYNOPSIS
       cwgen   [-g --groups=groups]   [-n --groupsize=groupsize]  [-n --group‐
       size=group_min-group_max]    [-r --repeat=repeat]    [-x --limit=limit]
       [-c --charset=charset]  [-h --help] [-V --version]

       cwgen  installed	 on  GNU/Linux systems understands both short form and
       long form command line options.	cwgen  installed  on  other  operating
       systems may understand only the short form options.

       Options	may  be	 predefined in the environment variable CWGEN_OPTIONS.
       If defined, these options are used first;  command  line	 options  take
       precedence.

DESCRIPTION
       cwgen  provides a simple method to generate groups of random characters
       for use as input into cw.  Command line options control the group size,
       number  of  groups,  and character set from which the random characters
       are selected.

   COMMAND LINE OPTIONS
       cwgen understands the following command line options.   The  long  form
       options may not be available in non-LINUX versions.

       -g, --groups
	      Specifies the number of groups of random characters to generate.
	      The default value is 128.

       -n, --groupsize
	      Specifies either the number of random characters in each	group,
	      if  a single value is given, or a range for the number of random
	      characters in each group if a dash-separated pair of  values  is
	      given.   If  a range is given, cwgen generates groups sized ran‐
	      domly between 'group_min' and 'group_max'.  The default value is
	      5.

       -r, --repeat
	      Specifies the number of times to repeat each group.  The default
	      value is 0, indicating that each group is printed just once.

       -x, --limit
	      Specifies an upper limit on the number  of  characters  printed.
	      This option is useful when using random group sizes, to ensure a
	      given amount of practice text.  The default value is 0, indicat‐
	      ing no upper limit on the number of characters printed.

       -c, --charset
	      Defines  the  character set from which the random characters are
	      selected.	  The	default	  value	  is   'ABCDEFGHIJKLMNOPQRSTU‐
	      VWXYZ0123456789'.

EXAMPLES
       Generate	 20 groups of 10 characters from the set EISH5, and sound them
       as Morse code.  Both  short-form	 and  long-form	 option	 examples  are
       shown:

	      cwgen -g 20 -n 10 -c "EISH5" | cw -w 25 -t 850

	      cwgen --groups=20 --groupsize=10 --charset="EISH5" | cw --wpm=25
	      --tone=850
