There are multiple problems with a typical approach to configuration:
- Each team member has its own configuration options. Committing such config will affect other team members.
- Production database password and API keys should not end up in repository.
- There are multiple servers: development, testing, production. Each should have its own configuration.
- Production database password and API keys should not end up in the repository.
- There are multiple server environments: development, testing, production. Each should have its own configuration.
- Defining all configuration options for each case is very repetitive and takes too much time to maintain.

by a set of files under `environments` directory. `init` command is used to switch between these. What it really does is
just copying everything from environment directory over the root directory where all applications are.

`-local.php`. These are added to `.gitignore` and never added to source code repository.
