The package resource API expects resource names to have their path parts separated with ``/``, *not* whatever the local path separator is. Do not use os.path operations to manipulate resource names being passed into the API. The package resource API is designed to work with normal filesystem packages, .egg files, and unpacked .egg files. It can also work in a limited way with .zip files and with custom PEP 302 loaders that support the ``get_data()`` method. i ( t absolute_importN( t get_importer( t six( t urllibt mapt filter( t utime( t mkdirt renamet unlink( t open( t isdirt split( t appdirs( t packagings pip._vendor.packaging.versions pip._vendor.packaging.specifierss" pip._vendor.packaging.requirementss pip._vendor.packaging.markersi sL Support for Python 3.0-3.2 has been dropped.

To allow usage of packages that explicitly require a newer version of Mac OS X, we must also know the current version of the OS.

The `fallback` flag indicates whether we should attempt to resolve older versions of a plugin if the newest version cannot be resolved. This method returns a 2-tuple: (`distributions`, `error_info`), where `distributions` is a list of the distributions found in `plugin_env` that were loadable, along with any other distributions that are needed to resolve their dependencies. `error_info` is a dictionary mapping unloadable plugin distributions to an exception instance describing the error that occurred.
