Overview

This cop makes sure that Ruby source files have snake_case names. Ruby scripts (i.e. source files with a shebang in the first line) are ignored.

The cop also ignores `.gemspec` files, because Bundler recommends using dashes to separate namespaces in nested gems (i.e. `bundler-console` becomes `Bundler::Console`). As such, the gemspec is supposed to be named `bundler-console.gemspec`.

Examples:

# bad
lib/layoutManager.rb

anything/usingCamelCase

# good
lib/layout_manager.rb

anything/using_snake_case.rake
