+#!/usr/bin/env bash
+
+# This script prepares and builds LLVM+Clang in a cycle
+# There are two purposes:
+# 1. Make sure the board can cope with sequential builds
+#    for as long as you wish (at least 2 days non-stop)
+# 2. Make sure the builds take reasonably the same time
+#
+# That's why the script has the following features:
+#
+# * "set +e" to not fail even if the build fails, as a
+#   subsequent commit can fix that, or even if the build
+#   fails, we're still stressing the hardware, not the build
+# * `date` before each step, so that you can compare
+#   multiple runs without having to find the `time` output
+# * Use -jCPUS, since we're not trying to get it faster, but
+#   reliable, and that tells us more than -jCPUS+2, etc.
+# * Time builds and tests separately, since tests tend to be
+#   more stable
+# * Don't use CCACHE, since that will defeat the purpose
+
