+"Python-dotenv reads key-value pairs from a .env file and can set them as environment
+variables.  It facilitates the development of applications following the 12 factors for
+building software-as-a-service apps as detailed by Adam Wiggins:
+@enumerate
+@item One codebase tracked in revision control, many deploys
+@item Explicitly declare and isolate dependencies
+@item Store config in the environment
+@item Treat backing services as attached resources
+@item Strictly separate build and run stages
+@item Execute the app as one or more stateless processes
+@item Export services via port binding
+@item Scale out via the process model
+@item Maximize robustness with fast startup and graceful shutdown
+@item Keep development, staging, and production as similar as possible
+@item Treat logs as event streams
+@item Run admin/management tasks as one-off processes
+@end enumerate")
