Command line parsing

[Kenneth Porter]

Can anyone point me to some code that illustrates proper use of the command 
line parsing machinery? I looked through the samples directory and only see 
one very tepid use of it, which doesn't call the base wxApp::OnInit method. 
How do I invoke that and still use the parser system?

For now my initial app needs a parameter to indicate which of several 
sections in a configuration file should be used, eg. invocation would be 
"myapp config1" or "myapp config2", with a default config assumed if no 
parameter is passed.
