+ * Name: Mass Tagger
+ * Author: Christian Walde <walde.christian@googlemail.com>
+ * License: WTFPL
+ * Description: Tag a bunch of images at once
+ * Documentation:
+ *  Once enabled, a new "Mass Tagger" box will appear on the left hand side of
+ *  post listings, with a button to enable the mass tagger. Once clicked JS will
+ *  add buttons to each image to mark them for tagging, and a field for
+ *  inputting tags will appear. Once the "Tag" button is clicked, the tags in
+ *  the text field will be added to marked images.
+ *
+ *  As of now only compatible with the lite theme.
