+
+    This object is used to access a filtered version of a repository without
+    altering the original repository object itself. We can not alter the
+    original object for two main reasons:
+    - It prevents the use of a repo with multiple filters at the same time. In
+      particular when multiple threads are involved.
+    - It makes scope of the filtering harder to control.
+
+    This object behaves very closely to the original repository. All attribute
+    operations are done on the original repository:
+    - An access to `repoview.someattr` actually returns `repo.someattr`,
+    - A write to `repoview.someattr` actually sets value of `repo.someattr`,
+    - A deletion of `repoview.someattr` actually drops `someattr`
+      from `repo.__dict__`.
+
+    The only exception is the `changelog` property. It is overridden to return
+    a (surface) copy of `repo.changelog` with some revisions filtered. The
+    `filtername` attribute of the view control the revisions that need to be
+    filtered.  (the fact the changelog is copied is an implementation detail).
+
+    Unlike attributes, this object intercepts all method calls. This means that
+    all methods are run on the `repoview` object with the filtered `changelog`
+    property. For this purpose the simple `repoview` class must be mixed with
+    the actual class of the repository. This ensures that the resulting
+    `repoview` object have the very same methods than the repo object. This
+    leads to the property below.
+
+        repoview.method() --> repo.__class__.method(repoview)
+
+    The inheritance has to be done dynamically because `repo` can be of any
+    subclasses of `localrepo`. Eg: `bundlerepo` or `httprepo`.
