Raven Post Labels

gistfile1.txt

<?php

/**
 * Post Label.
 *
 * Returns a noun representing the type or format of the global
 * post object. This function is used internally by the
 * raven_entry_meta_taxonomy() function to create a sentence much
 * like the following: "This Status Update is filed under News."
 * where "Status Update" is the post label and "News" is the category.
 *
 * A "post label" can be one of three things:'
 * post format, custom post_type label or the mime type of an attachment.
 *
 * For "posts" having a post format, a string representing the format will be used.
 * If no format has been defined (assumung "standard" post format) This function
 * will use the term "post".
 *
 * For all other post_types, Raven will use the values defined in
 * the post_type's "labels" array for singular and plural values.
 *
 * The output of this function may be extended by using the built-in filters:
 *
 * 'raven_post_label_single' and 'raven_post_label_plural'
 *
 * @return    array     Index "0" is the singular form while index "1" is the plural form.
 *
 * @access    private
 * @since     Raven 1.0
