## config.set_env_vars()


Loads environment variables from configuration files or the environment.


Usage

``` python
config.set_env_vars()
```


If the ENV variable is not set, defaults to 'development'. Loads the first `.env.{ENV}` (or `.env`) found, then fills any variable still unset from the site profile and user config (`omero_screen.settings`). Nothing is required at import: a missing OMERO login is reported when a connection is made.
