From: Han-Wen Nienhuys <hanwen@xxxxxxxxxx>
The reftable library is integrates with Git, so it become a first class
supported storage mechanism, but is sufficiently complex that other
projects (e.g. libgit2) may want to consume the same source code.
To make this possible, the library also compiles completely standalone, which is
demonstrated with the Bazel BUILD/WORKSPACE files that this commit adds.

+This directory contains an implementation of the reftable library.
+
+The library is integrated into the git-core project, but can also be built
+standalone, by compiling with -DREFTABLE_STANDALONE. The standalone build is
+exercised by the accompanying BUILD/WORKSPACE files, and can be run as
+
+ bazel test :all
+
+It includes a fragment of the zlib library to provide uncompress2(), which is a
+recent addition to the API. zlib is licensed as follows:
