The difference between -version and --dry-run is only the locating of 
the main class, which will be an obvious failure without --dry-run. It 
just doesn't seem to carry its weight as a new command-line arg. I had 
assumed the loading and/or initialization was needed to ensure the 
module system was all configured correctly, but based on what you have 
said that seems not to be the case.
