class HasFileTree(Matcher):

"""Match a directory on disk against a file tree shape.

The specified shape contains everything that is allowed to exist in the

matched directory. Parent directories that are implied by actual entries

(e.g. 'foo/bar/' implies that 'foo/' exists) will be automatically added.

Attributes can be matched using testtools matchers, e.g.::

{'foo': {CONTENTS: Contains("Hello")}}

Or will be simply checked for equality if they aren't matchers. Thus::

{'foo': {CONTENTS: Equals("Hello")}}

is equivalent to::

{'foo': {CONTENTS: "Hello"}}

``from_rough_spec`` also works with matchers, so you could call

``HasFileTree`` like this, if you want::

HasFileTree(from_rough_spec([('foo', Contains("Hello")), 'bar/']))

If the disk contains any files or directories that aren't specified in the

matcher and aren't implied directories, then it will mismatch. Likewise,

if there are entries in the matcher spec that don't exist on disk, it will

mismatch.
