Total complexity of your project is 2264ish.  20% (486/2264) of your  
complexity lies in RGB, and I'm guessing that its all building up  
your constants (from the names in your report).

What does `flog ... | grep -v '^ '` give (just the top-level stuff)

For RubyGems:

Total score = 7318.5427518653

Server#run: (203.9)
OpenURI#open_http: (161.0)
Policy#verify_gem: (135.9)
main#none: (118.0)
Validator#alien: (105.8)

Server#run is a good candidate for refactoring (3% of complexity!),  
as is Policy#verify_gem (2%!).  main#none is just toplevel code.   
(OpenURI is in there for fixing proxy stuff :/)

Note: values are an arbitrary, they only matter relative to the  
total, and relative to other modules or methods.
