On level 2 one gets a rough overview. Those who want to go into the details of the algorithm described in <a href="biblio.htm#Distler05"><cite>Distler05</cite></a> and of the implementatio find the information on level 3-4 helpful. <p> To use the package in silent mode the info level can be given the value 0. <p> [<a href = "chapters.htm">Up</a>] [<a href ="CHAP002.htm">Previous</a>] [<a href ="CHAP004.htm">Nex <P> <address>Radiroot manual<br>March 2022 </address></body></html>
