/*
 * CUSTOM POST TYPE ARCHIVE TEMPLATE
 *
 * This is the custom post type archive template. If you edit the custom post type name,
 * you've got to change the name of this template to reflect that name change.
 *
 * For Example, if your custom post type is called "register_post_type( 'bookmarks')",
 * then your template name should be archive-bookmarks.php
 *
 * For more info: http://codex.wordpress.org/Post_Type_Templates
