It just occurred to me that I have a non-web case on my desk now. It 
converts a file scraped from a HTML page into a couple of fixed-length 
files that are imported into a database. Problem is, the government 
agency that creates the HTML page tweaks the format now and again, or 
adds new information, which makes maintenance an ongoing issue. This 
seems like a good use for the CoR architechture, since each Command can 
scan for one of the many possible input formats. If it's not yours, pass 
it along =:)

I've a maintenance ticket open for this now, so I'll think I'll migrate 
it to Chain. The best part is that the application is already fully 
tested, and so it will be a good show of using Unit Tests in a non-web 
applicaton too.
