+<p>A Lisp program might want to be notified of text affected by
+incremental parsing.  For example, inserting a comment-closing token
+converts text before that token into a comment.  Even
+though the text is not directly edited, it is deemed to be &ldquo;changed&rdquo;
+nevertheless.
+</p>
+<p>Emacs lets a Lisp program to register callback functions
+(a.k.a. <em>notifiers</em>) for this kind of changes.  A notifier
+function takes two arguments: <var>ranges</var> and <var>parser</var>.
+<var>ranges</var> is a list of cons cells of the form <code>(<var>start</var>&nbsp;.&nbsp;<var>end</var>)</code><!-- /@w -->, where <var>start</var> and <var>end</var> mark the start and the
+end positions of a range.  <var>parser</var> is the parser issuing the
+notification.
+</p>
+<p>Every time a parser reparses a buffer, it compares the old and new
+parse-tree, computes the ranges in which nodes have changed, and
+passes the ranges to notifier functions.
