-------------------------------------------------

The assumption I made was not correct. Both rendering methods can stay protected as it would colst too much effort to use them for gettig a nice looking output.
Nevertheless my requirement having help content rendered into a StringBuffer had to be solved. So I added kind of an indirection to the printng exposing additional (public) rendering functions. One can now decide if to print or to render into a SB.

Due to some strage behavior regarding the newLine usage renderHelp() is the only method which may currently not be "generic". 

I attached my version of the HelpFormatter to give you a better idea of the whole thing.

Cheers, Ulf

[Update] renderHelp() has been thrown out.

> Under certain circumstances it is usefull that HelpFormatter printing methods return a string buffer which can be used in further processing instead of direct printing to a PW or std.out. 
> When having a closer look at the source one can easily retrieve string buffers with formatted text by changing the visibility of renderOptions() and renderWrappedText()  from protected to public. This will make the "core" formatting methods available without adding additional functionallity to the HelpFormatter.
> Another option would be to add a set of print....() methods returning the SB instead of printing its content.
