+       "Org Ref is an Emacs library that provides rich support for citations,
+labels and cross-references in Org mode.
+
+The basic idea of Org Ref is that it defines a convenient interface to insert
+citations from a reference database (e.g., from BibTeX files), and a set of
+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
+scientific publication.  Org Ref is also useful for research documents and
+notes.")

-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.
-
