+About the fork
+--------------
+
+This project is a fork of apparently dead "django-pagination" project
+originally written by 'Eric Florenzano'. It is maintained by the Linaro
+Validation/Infrastructure team. Latest releases can be found on launchpad and
+pypi.
+
+
+How to use linaro-django-pagination
+-----------------------------------
+
+``linaro-django-pagination`` allows for easy Digg-style pagination without
+modifying your views.
+
+There are really 5 steps to setting it up with your projects (not including
+installation, which is covered in INSTALL.txt in this same directory.)
+
+1. List this application in the ``INSTALLED_APPS`` portion of your settings
+ file. Your settings file might look something like::
+
+ INSTALLED_APPS = (
+ # ...
+ 'linaro_django_pagination',
+ )
+
+
+2. Install the pagination middleware. Your settings file might look something
+ like::
+
+ MIDDLEWARE_CLASSES = (
+ # ...
+ 'linaro_django_pagination.middleware.PaginationMiddleware',
+ )
+
+3. If it's not already added in your setup, add the request context processor.
+ Note that context processors are set by default implicitly, so to set them
+ explicitly, you need to copy and paste this code into your under
+ the value TEMPLATE_CONTEXT_PROCESSORS::
+
+ ("django.core.context_processors.auth",
+ "django.core.context_processors.debug",
+ "django.core.context_processors.i18n",
+ "django.core.context_processors.media",
+ "django.core.context_processors.request")
+
+4. Add this line at the top of your template to load the pagination tags:
+
+ {% load pagination_tags %}
+
+
+5. Decide on a variable that you would like to paginate, and use the
+ autopaginate tag on that variable before iterating over it. This could
+ take one of two forms (using the canonical ``object_list`` as an example
+ variable):
+
+ {% autopaginate object_list %}
+
+ This assumes that you would like to have the default 20 results per page.
+ If you would like to specify your own amount of results per page, you can
+ specify that like so:
+
+ {% autopaginate object_list 10 %}
+
+ Note that this replaces ``object_list`` with the list for the current page, so
+ you can iterate over the ``object_list`` like you normally would.
+
+
+6. Now you want to display the current page and the available pages, so
+ somewhere after having used autopaginate, use the paginate inclusion tag:
+
+ {% paginate %}
+
+ This does not take any arguments, but does assume that you have already
+ called autopaginate, so make sure to do so first.
+
+
+That's it! You have now paginated ``object_list`` and given users of the site
+a way to navigate between the different pages--all without touching your views.
+
+
+Optional Settings
+-----------------
+
+In linaro-django-pagination, there are no required settings. There are,
+however, a small set of optional settings useful for changing the default
+behavior of the pagination tags. Here's an overview:
+
+``PAGINATION_DEFAULT_PAGINATION``
+ The default amount of items to show on a page if no number is specified.
+
+``PAGINATION_DEFAULT_WINDOW``
+ The number of items to the left and to the right of the current page to
+ display (accounting for ellipses).
+
+``PAGINATION_DEFAULT_ORPHANS``
+ The number of orphans allowed. According to the Django documentation,
+ orphans are defined as::
+
+ The minimum number of items allowed on the last page, defaults to zero.
+
+``PAGINATION_INVALID_PAGE_RAISES_404``
+ Determines whether an invalid page raises an ``Http404`` or just sets the
+ ``invalid_page`` context variable. ``True`` does the former and ``False``
+ does the latter.

-How to use django-pagination
-----------------------------
-
-``django-pagination`` allows for easy Digg-style pagination without modifying
-your views.
-
-There are really 5 steps to setting it up with your projects (not including
-installation, which is covered in INSTALL.txt in this same directory.)
-
-1. List this application in the ``INSTALLED_APPS`` portion of your settings
- file. Your settings file might look something like::
-
- INSTALLED_APPS = (
- # ...
- 'pagination',
- )
-
-
-2. Install the pagination middleware. Your settings file might look something
- like::
-
- MIDDLEWARE_CLASSES = (
- # ...
- 'pagination.middleware.PaginationMiddleware',
- )
-
-3. If it's not already added in your setup, add the request context processor.
- Note that context processors are set by default implicitly, so to set them
- explicitly, you need to copy and paste this code into your under
- the value TEMPLATE_CONTEXT_PROCESSORS::
-
- ("django.core.context_processors.auth",
- "django.core.context_processors.debug",
- "django.core.context_processors.i18n",
- "django.core.context_processors.media",
- "django.core.context_processors.request")
-
-4. Add this line at the top of your template to load the pagination tags:
-
- {% load pagination_tags %}
-
-
-5. Decide on a variable that you would like to paginate, and use the
- autopaginate tag on that variable before iterating over it. This could
- take one of two forms (using the canonical ``object_list`` as an example
- variable):
-
- {% autopaginate object_list %}
-
- This assumes that you would like to have the default 20 results per page.
- If you would like to specify your own amount of results per page, you can
- specify that like so:
-
- {% autopaginate object_list 10 %}
-
- Note that this replaces ``object_list`` with the list for the current page, so
- you can iterate over the ``object_list`` like you normally would.
-
-
-6. Now you want to display the current page and the available pages, so
- somewhere after having used autopaginate, use the paginate inclusion tag:
-
- {% paginate %}
-
- This does not take any arguments, but does assume that you have already
- called autopaginate, so make sure to do so first.
-
-
-That's it! You have now paginated ``object_list`` and given users of the site
-a way to navigate between the different pages--all without touching your views.
-
-
-Optional Settings
-------------------
-
-In django-pagination, there are no required settings. There are, however, a
-small set of optional settings useful for changing the default behavior of the
-pagination tags. Here's an overview:
-
-``PAGINATION_DEFAULT_PAGINATION``
- The default amount of items to show on a page if no number is specified.
-
-``PAGINATION_DEFAULT_WINDOW``
- The number of items to the left and to the right of the current page to
- display (accounting for ellipses).
-
-``PAGINATION_DEFAULT_ORPHANS``
- The number of orphans allowed. According to the Django documentation,
- orphans are defined as::
-
- The minimum number of items allowed on the last page, defaults to zero.
-
-``PAGINATION_INVALID_PAGE_RAISES_404``
- Determines whether an invalid page raises an ``Http404`` or just sets the
- ``invalid_page`` context variable. ``True`` does the former and ``False``
- does the latter.
