designing a re-usable pager element

I want to create a re-usable content piece that will display a pager, my
html looks like:

    <div class="pagination">
        <ul>
            <li><a href="">Prev</a></li>
            <li class="active"><a href="">1</a></li>
            <li><a href="">2</a></li>
            <li><a href="">3</a></li>
            <li><a href="">Next</a></li>
        </ul>
    </div>

Now to make it re-usable, I want to pass in the following information:

1. base_url  e.g. www.example.com/post/list
2. current_page e.g. 3
3. total items e.g. 100
4. items per page e.g. 25

So given this information, I should see 4 page links (100 items / 25 = 4):


    <div class="pagination">
        <ul>
            <li><a href="www.example.com/post/list?page=2">Prev</a></li>
            <li><a href="www.example.com/post/list?page=1">1</a></li>
            <li><a href="www.example.com/post/list?page=2">2</a></li>
            <li class="active"><a href="www.example.com/post/list?page=3
">3</a></li>
            <li><a href="www.example.com/post/list?page=4">4</a></li>
            <li><a href="www.example.com/post/list?page=4">Next</a></li>
        </ul>
    </div>


How could I create a macro for this in freemarker?
