Generates more specific previous / next post links based on referrer.

== Description ==

The default `previous_post_link()` and `next_post_link()` have an option to restrict adjacent posts to the current category. This plugin takes it one step further:

If you visit an archive page (category, tag, date, author, search etc.) and then visit a single post from that page, the `previous_post_smart()` and `next_post_smart()` will point only to the other posts in that archive page.

This is particularly useful for photoblogs (that’s where I use it).

= Template tags =
You can simply replace `previous_post_link()` with `previous_post_smart()` and keep the first two arguments: $format & $title. 

If there isn’t a previous post in a set, the normal template tag will be called.

The same goes for `next_post_link()`.

There is also a `referrer_link()` template tag which displays a link to the referrer. Args:

* $format = '%link'
* $title = '%title'
* $sep = '»'
* $seplocation = 'left'

You can learn more about these by looking at the template-tags.php file.

== Installation ==

1. Unzip the archive and put the folder into your plugins folder (/wp-content/plugins/).
1. Activate the plugin from the Plugins admin menu.
1. Insert the template tags in your theme as needed.

== Frequently Asked Questions ==

= Does it work with my favourite caching plugin? =
Short answer: it depends.

It won't work properly with WP Super Cache because it generate links specific to each user.

It will work with DB Cache because it doesn't interact with the database at all (it uses cookies).
