-"""
-Wrappers to make file-like objects cooperative.
-
-.. class:: FileObject
-
- The main entry point to the file-like gevent-compatible behaviour. It will be defined
- to be the best available implementation.
-
-There are two main implementations of ``FileObject``. On all systems,
-there is :class:`FileObjectThread` which uses the built-in native
-threadpool to avoid blocking the entire interpreter. On UNIX systems
-(those that support the :mod:`fcntl` module), there is also
-:class:`FileObjectPosix` which uses native non-blocking semantics.
-
-A third class, :class:`FileObjectBlock`, is simply a wrapper that executes everything
-synchronously (and so is not gevent-compatible). It is provided for testing and debugging
-purposes.
-
-Configuration
-=============
-
-You may change the default value for ``FileObject`` using the
-``GEVENT_FILE`` environment variable. Set it to ``posix``, ``thread``,
-or ``block`` to choose from :class:`FileObjectPosix`,
-:class:`FileObjectThread` and :class:`FileObjectBlock`, respectively.
-You may also set it to the fully qualified class name of another
-object that implements the file interface to use one of your own
-objects.
-
-.. note:: The environment variable must be set at the time this module
- is first imported.
