I am using the App::Options library for processing config files and command line options. I have two parameters, of which one of the two must be specified. Since I do not see any way to specify this via the interface, I am adding a conditional call to check that at least one of the options has a value.

What would be nice, is to output the -help information when an error is encountered, just as if the user had omitted a required parameter. Does anyone know how this can be done?
