Indicate paginated content

[alanorth]

Google (for one) recommends indicating paginated content so they can index and display series of pages more intelligently and reduce displaying duplicated content. In our case this would come in handy on our index and "page 2", "page 3" etc, which are all continuations of the same logical "list of blog posts" page.

The index page would have the following:

<link rel="next" href="https://nairobilug.or.ke/index2.html" />

Then the second index page would have the following:

<link rel="prev" href="https://nairobilug.or.ke/" />
<link rel="next" href="https://nairobilug.or.ke/index3.html" />

Not sure how this would work, because our blog is static, so the logic would have to happen at blog generation time. Can Jinja2 know how many pages we have, and which page it's on? Ping @raymondwanyoike @jasonrogena
