+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.

+Subject: Set package configuration options
+Forwarded: not-needed
+
+Configure Abseil for Debian.
+
+  - Set the SONAME appropriately.
+
+  - To minimize the possibility of future ABI breakage, treat absl::any,
+    absl::optional, absl::string_view, and absl::variant as their own types
+    (rather than aliases for the std:: versions), and compile everything in an
+    inline namespace.
+
+  - Enable upstream's hardened build mode.
+
+  - Disable Intel SSE2 on i386, since Debian supports some i386 processors
+    without that extension. Keep it enabled on amd64, since all amd64 processors
+    have it.
+
+  - Disable Intel SSSE3 entirely, since no i386 processor supports it and Debian
+    supports amd64 processors without it.

+
+Linux on MIPS, PA-RISC, RISC-V, and SystemZ doesn’t expose the nominal CPU
+frequency via /sys, so don’t worry if `NominalCPUFrequency` returns 1.0 on those
+platforms.
+
+Some POWER machines expose the CPU frequency; others do not. Since we can’t
+predict which type of machine the tests will run on, simply disable testing for
+`NominalCPUFrequency` on POWER.
