INSTALLATION INSTRUCTIONS
-------------------------

1. download the file and place it into your wp-content/plugins. directory.
2. do  "tar zxvf mtg.tar.gz" to unzip the file into your plugins directory.
3. Install Wordnet.
4. Install Lingua.
5. Get the WordPress plugin HeadMeta and install it.
5. Your webserver must be able to access the Lingua and Wordnet files, so please make sure it does.

That should be it. Enable the plugin, open an old entry and do "Save and continue editing". A new custom field key-value should be generated.
Check the source code of the related page to make sure you are generating keywords.

HEADMETA HACK
-------------
HeadMeta publishes keywords on single-entry pages only. The following hack can be used to place keywords in the content of pages of groups of entries.

Replace the function headmeta() in the source of headmeta.php with this one:

function headmeta() {
    global $single, $posts, $post_meta_cache;

    foreach($post_meta_cache as $post)
    {
        $metavals = $post['head_meta'];
        $linkvals = $post['head_link'];

        // Generate the tags
        if (count($metavals)) {
            foreach ($metavals as $meta) {
                $tag = "<meta $meta />";
                print "$tag\n";
            }
        }

        if (count($linkvals)) {
            foreach ($linkvals as $link) {
                $tag = "<link $link />";
                print "$tag\n";
            }
        }
    }
}
