Crate dotenv

This crate provides a configuration loader in the style of the ruby dotenv gem. This library is meant to be used on development or testing environments in which setting environment variables is not practical. It loads environment variables from a .env file, if available, and mashes those with the actual environment variables provided by the operating system.
