+Abseil for Debian
+-----------------
+
+libabsl-dev installs a number of files to 'internal' directories. In general,
+your project should not directly include any files from these directories; they
+may change without warning. If you think you need something from one of those
+files, please report a bug with reportbug(1).

+Description: extensions to the C++ standard library
+ Abseil is an open-source collection of C++ library code designed to augment the
+ C++ standard library. The Abseil library code is collected from Google's C++
+ codebase and has been extensively tested and used in production. In some cases,
+ Abseil provides pieces missing from the C++ standard; in others, Abseil
+ provides alternatives to the standard for special needs.

+Bug-Debian: https://bugs.debian.org/970333
+
+Improve CMake support by finding the Threads module with find_dependency

+From: Benjamin Barenblat <bbaren@google.com>
+Subject: Correct Apache license headers
+Forwarded: yes
+Applied-Upstream: https://github.com/abseil/abseil-cpp/commit/bd317cae3bc2630d1b12c5f1d77036e937d1d725
+
+This repository has always been licensed under the Apache license, but some
+files lacked headers to locally indicate that fact. Add the appropriate headers.
+
+The author works at Google. Upstream applied this patch as Piper revision
+310223650 and exported it to GitHub; the Applied-Upstream URL above points to
+the exported commit.
