+/**
+ * Tag-closer extension for CodeMirror.
+ *
+ * This extension adds a "closeTag" utility function that can be used with key bindings to 
+ * insert a matching end tag after the ">" character of a start tag has been typed.  It can
+ * also complete "</" if a matching start tag is found.  It will correctly ignore signal
+ * characters for empty tags, comments, CDATA, etc.
+ *
+ * The function depends on internal parser state to identify tags.  It is compatible with the
+ * following CodeMirror modes and will ignore all others:
+ * - htmlmixed
+ * - xml
+ *
+ * See demos/closetag.html for a usage example.
+ * 
+ * @author Nathan Williams <nathan@nlwillia.net>
+ * Contributed under the same license terms as CodeMirror.
