This module was created to fill the need for *two-dimensional* environment/host management.
* What's an environment? An environment is a development or server location where a full Drupal build (possibly including multiple hosts) is set up. In our work, we tend to have
1) a primary 'dev' environment (site.dev.ourwork.com),
2) local environments for each developer (site.dev.local),
3) a staging environment (staging.site.com),
4) a live site (www.site.com), etc.
But each of these environments can have multiple sites/hosts, making the number of actual hosts to track and toggle grow exponentially.
The domain_access module does a good job of tracking hosts, but in only one environment.
The goal for now is not to manage deployment between multiple environments, but rather to allow for managing content between the environments, and more generally to have code- and user-level context awareness of each environment. The module is currently a barebones API, to be expanded upon for various use cases. I'm interested in hearing what use cases people have.
Envts has no UI yet, but simply allows other modules to define environments with a hook. (Anyone is welcome to create a UI for the module, since my time is limited!)
