[osg-users] Argument parsing and help statements in osgviewer

[Eric Sokolowsky]

I have been away from OSG development for some time and am getting back 
into it. I'm trying to see if my application will port to OSG 2.4 using 
the osgViewer instead of OSG 1.2 using osgProducer::Viewer. As I was 
running the new osgviewer application I noticed that there are some 
command-line options missing when "osgviewer --help" is invoked, 
particularly "--window" and "--screen". The help is placed from the 
osgviewer application and the place where the options are read is now in 
the osgviewer application source. Both of these things should be in the 
osgViewer source to ease maintainability and reusability. If these 
options and help statements are in osgViewer then they don't need to be 
repeated for every application. I'll work on the patch if others think 
it's a good idea. Comments?
