+# NOTE The manylinux1 policy mandates CentOS-5. We replace it with CentOS-6 in
+# order to satisfy the build of capnproto library (a nupic.core dependency),
+# which requires some headers and symbols not present on CentOS-5 (e.g.,
+# signalfd.h, pipe2, O_NONBLOCK, SOCK_NONBLOCK, etc.). See
+# https://github.com/sandstorm-io/capnproto/issues/350.
