Comment (by mojca@…):

 I'm also thinking about inclusion of the following patch to show help in
 HTML format rather than just in text mode:
    * http://sourceforge.net/p/gnuplot/patches/707/

 It seems very useful. I got it working with wxt and I still need to debug
 what's wrong with qt, but it looks nice.
