Overview

This class handles loading files (a.k.a. features in Ruby) specified by --require command line option and require directive in the config.

Normally, the given string is directly passed to require. If a string beginning with . is given, it is assumed to be relative to the given directory.

If a string containing - is given, it will be used as is, but if we cannot find the file to load, we will replace - with / and try it again as when Bundler loads gems.
