+/**
+ * Tag-closer extension for CodeMirror.
+ *
+ * This extension adds an "autoCloseTags" option that can be set to
+ * either true to get the default behavior, or an object to further
+ * configure its behavior.
+ *
+ * These are supported options:
+ *
+ * `whenClosing` (default true)
+ * Whether to autoclose when the '/' of a closing tag is typed.
+ * `whenOpening` (default true)
+ * Whether to autoclose the tag when the final '>' of an opening
+ * tag is typed.
+ * `dontCloseTags` (default is empty tags for HTML, none for XML)
+ * An array of tag names that should not be autoclosed.
+ * `indentTags` (default is block tags for HTML, none for XML)
+ * An array of tag names that should, when opened, cause a
+ * blank line to be added inside the tag, and the blank line and
+ * closing line to be indented.
+ * `emptyTags` (default is none)
+ * An array of XML tag names that should be autoclosed with '/>'.
+ *
+ * See demos/closetag.html for a usage example.

+ // document. Line objects hold arrays (markedSpans) containing
+ // {from, to, marker} object pointing to such marker objects, and
+ // indicating that such a marker is present on that line. Multiple
+ // lines may point to the same marker when it spans across lines.
+ // The spans will have null for their from/to properties when the
+ // marker continues beyond the start/end of the line. Markers have
+ // links back to the lines they currently touch.
