+functional Org links for citations, cross-references and labels that export
+properly to LaTeX, and that provide clickable functionality to the user.  Org
+Ref interfaces with Helm BibTeX to facilitate citation entry, and it can also
+use RefTeX.
+
+It also provides a fairly large number of utilities for finding bad citations,
+extracting BibTeX entries from citations in an Org file, and functions to
+create and modify BibTeX entries from a variety of sources, most notably from
+a DOI.
+
+Org Ref is especially suitable for Org documents destined for LaTeX export and

-From 52add5896661d186dec284ed646a4b33b607d2c7 Mon Sep 17 00:00:00 2001
-From: Jerome Jiang <jianj@google.com>
-Date: Wed, 23 May 2018 15:43:00 -0700
-Subject: [PATCH] VP8: Fix use-after-free in postproc.
-
-The pointer in vp8 postproc refers to show_frame_mi which is only
-updated on show frame. However, when there is a no-show frame which also
-changes the size (thus new frame buffers allocated), show_frame_mi is
-not updated with new frame buffer memory.
-
-Change the pointer in postproc to mi which is always updated.
-
-Bug: 842265
-Change-Id: I33874f2112b39f74562cba528432b5f239e6a7bd
