Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Reads environments from a directory on disk. Each environment is represented as a sub-directory. The environment's manifest setting is the `manifest` directory of the environment directory. The environment's modulepath setting is the global modulepath (from the `[master]` section for the master) prepended with the `modules` directory of the environment directory.
