+# Specify the desired LLVM version in an overlay to avoid the use of
+# mismatching versions.
+#
+# The llvmPackages that we take things (clang, libc++ and such) from
+# is specified explicitly to be llvmPackages_11 to keep the
+# bootstrap-tools stable.  However, tools like otool,
+# install_name_tool and strip are taken straight from stdenv.cc,
+# which, after the bump, is a different LLVM version altogether.
+#
+# The original intent was that bootstrap-tools specified LLVM 11
+# exhaustively but it didn't. That should be rectified with this
+# PR. As to why stick with 11? That's just to keep the
+# bootstrap-tools unchanged.
