1	+ === Per page add to head ===
2	+ Contributors: Erikvona
3	+ Plugin Name: Per page add to head
4	+ Tags: head, css, favicon
5	+ Author URI: http://erikvona.com/over-mij
6	+ Author: Erik von Asmuth (Erikvona)
7	+ Requires at least: 3.5
8	+ Tested up to: 3.6
9	+ Stable tag: 0.2 beta
10	+ License: GPLv2 or later

13	+
14	+ This plugin adds content between the head tags for specific WordPress posts, or every WordPress post.
15	+
16	+ == Description ==
17	+
18	+ Ever got really annoyed how much effort it took to add <style> tags for just one page into the <head> section of a page, using WordPress? Well, I did. So I made this plugin for exactly that purpose. It just adds whatever you give it to the <head> tag. With a size of 8KB, and no use of any client side code, efficiency is taken care of. You can also use it to add <meta> tags, for SEO, auto-refresh, Google Analytics, or anything else you want to put in there.
19	+
20	+ Offcourse, you can also use it to add your own stylesheets and JavaScript files. Anything that normally goes in the head section is fine.
21	+
22	+ Add to head also features an option under settings to add some text inside <head> on every page. Ideal for favicons, Modern UI start screen icons, or style sheets if you’re too lazy to make a child theme.
23	+
24	+ Just install the plugin, activate it, make sure it is showing in your post editor by clicking screen options and checking add to head while editing a page, and add stuff!
25	+
26	+ Warning: Don't put stuff in the head tags that shouldn't be there! This plugin does not validate anything, and it is really easy to invalidate your HTML by making mistakes in your head tag
27	+
28	+ == Installation ==
29	+
30	+ Installation is plain and simple
31	+
32	+ 1. Add the plugin to WordPress by searching and installing, uploading a zip, FTP copy, or some other way, and activate it
33	+ 1. Make sure the add to head box is visible, by checking add to head in screen options within the plugin/post editor
34	+ 1. Add your head stuff to the posts!
35	+ 1. You can also add head to all posts! Just use settings -> add head to every page
36	+
37	+ == Changelog ==
38	+
39	+ = 0.2 beta =
40	+ Initial release for the WordPress plugin repository
