Plugin Name: Make Static
Version: 1.0
Plugin URI: http://www.theonering.net/staff/corvar/software/wordpress.html#makestatic
Description: Make a static copy of a dynamic page
Author: William "Corvar" Thomas
Author URI: http://www.theonering.net/

Installation: The two variables (baseurl and basedir) will need to be set for your scenario.
Only supports the default permalink format of yyyy/mm/dd/post-name

Usage:
Create a custom field for a post with a key of "static" and a value of "on"
When the post is saved, it will create a static version.

Rewrite Rules: To seemlessly use this plugin, additional
RewriteRules/Conds will be needed.  These should come between the
RewriteBase and first RewriteRule supplied by WordPress's permalink.
They should be of the form:
RewriteCond /usr/share/%{REQUEST_URI}.html -f
RewriteRule ^archives/(.*)   /wordpress/archives/$1 [L]
In that example, REQUEST_URI would be of the form
'/wordpress/archives/2004/9/21/the-name-of-post', wordpress is
installed in '/usr/share/wordpress'

Requires: curl
