   <!-- options-start -->
 Valid options are: <p/>
 
 <pre> -h
  Prints this help.</pre>
 
 <pre> -o &lt;file&gt;
  The name of the output file, otherwise the generated data is
  printed to stdout.</pre>
 
 <pre> -r &lt;name&gt;
  The name of the relation.</pre>
 
 <pre> -d
  Whether to print debug informations.</pre>
 
 <pre> -S
  The seed for random function (default 1)</pre>
 
 <pre> -a &lt;num&gt;
  The number of attributes (default 10).</pre>
 
 <pre> -c
  Class Flag, if set, the cluster is listed in extra attribute.</pre>
 
 <pre> -b &lt;range&gt;
  The indices for boolean attributes.</pre>
 
 <pre> -m &lt;range&gt;
  The indices for nominal attributes.</pre>
 
 <pre> -k &lt;num&gt;
  The number of clusters (default 4)</pre>
 
 <pre> -G
  Set pattern to grid (default is random).
  This flag cannot be used at the same time as flag I.
  The pattern is random, if neither flag G nor flag I is set.</pre>
 
 <pre> -I
  Set pattern to sine (default is random).
  This flag cannot be used at the same time as flag I.
  The pattern is random, if neither flag G nor flag I is set.</pre>
 
 <pre> -N &lt;num&gt;..&lt;num&gt;
  The range of number of instances per cluster (default 1..50).
  Lower number must be between 0 and 2500,
  upper number must be between 50 and 2500.</pre>
 
 <pre> -R &lt;num&gt;..&lt;num&gt;
  The range of radius per cluster (default 0.1..1.4142135623730951).
  Lower number must be between 0 and SQRT(2), 
  upper number must be between SQRT(2) and SQRT(32).</pre>
 
 <pre> -M &lt;num&gt;
  The distance multiplier (default 4.0).</pre>
 
 <pre> -C &lt;num&gt;
  The number of cycles (default 4).</pre>
 
 <pre> -O
  Flag for input order is ORDERED. If flag is not set then 
  input order is RANDOMIZED. RANDOMIZED is currently not 
  implemented, therefore is the input order always ORDERED.</pre>
 
 <pre> -P &lt;num&gt;
  The noise rate in percent (default 0.0).
  Can be between 0% and 30%. (Remark: The original 
  algorithm only allows noise up to 10%.)</pre>
