Command line option parsing using Lambda functions with NDesk.Options

I had been doing a lot of work on monodocer, and the warning about Mono.GetOptions being obsolete was getting annoying. So after killing an afternoon coming up with a similar reflection-based alternative, it dawned on me that (1) any such alternative would not be "simple", and (2) using such a library would have a high code overhead. After thinking back on the previous option parsing libraries I've used, I remembered Perl's Getopt::Long library, which permits short and concise declarations of the options a program supports.
