def get_pages(parser, token):
    """Add to context the list of page links.

    Usage:

    .. code-block:: html+django

        {% get_pages %}

    This is mostly used for Digg-style pagination.
    This call inserts in the template context a *pages* variable, as a sequence
    of page links. You can use *pages* in different ways:

    - just print *pages* and you will get Digg-style pagination displayed:

    .. code-block:: html+django

        {{ pages }}

    - display pages count:

    .. code-block:: html+django

        {{ pages|length }}

    - check if the page list contains more than one page:

    .. code-block:: html+django

        {{ pages.paginated }}
        {# the following is equivalent #}
        {{ pages|length > 1 }}

    - get a specific page:

    .. code-block:: html+django

        {# the current selected page #}
        {{ pages.current }}

        {# the first page #}
        {{ pages.first }}

        {# the last page #}
        {{ pages.last }}

        {# the previous page (or nothing if you are on first page) #}
        {{ pages.previous }}

        {# the next page (or nothing if you are in last page) #}
        {{ pages.next }}

        {# the third page #}
        {{ pages.3 }}
        {# this means page.1 is the same as page.first #}

        {# the 1-based index of the first item on the current page #}
        {{ pages.current_start_index }}

        {# the 1-based index of the last item on the current page #}
        {{ pages.current_end_index }}

        {# the total number of objects, across all pages #}
        {{ pages.total_count }}

        {# the first page represented as an arrow #}
        {{ pages.first_as_arrow }}

        {# the last page represented as an arrow #}
        {{ pages.last_as_arrow }}

    - iterate over *pages* to get all pages:

    .. code-block:: html+django

        {% for page in pages %}
            {# display page link #}
            {{ page }}

            {# the page url (beginning with "?") #}
            {{ page.url }}

            {# the page path #}
            {{ page.path }}

            {# the page number #}
            {{ page.number }}

            {# a string representing the page (commonly the page number) #}
            {{ page.label }}

            {# check if the page is the current one #}
            {{ page.is_current }}

            {# check if the page is the first one #}
            {{ page.is_first }}

            {# check if the page is the last one #}
            {{ page.is_last }}
        {% endfor %}

    You can change the variable name, e.g.:

    .. code-block:: html+django

        {% get_pages as page_links %}

    Must be called after ``{% paginate objects %}``.
