+# Clean workspace.
+# This should be the first and last step of every jenkins build:
+# a) to make sure the workspace has no build artifacts from previous runs.
+# b) to reduce disk space lost to unused binaries; parallel and/or matrix
+#    builds create numerous workspaces, blowing up disk usage.
+# Note that if a build fails, the last steps will not run, hence calling this
+# as last step cleans only in case there was no build failure, i.e. where we
+# don't need to keep anything anyway.
+#
+# Assume $PWD is a git clone's root dir. Usually, that's also the jenkins
+# workspace root. Do not wipe subdir 'layer1-headers' as well as all dirs under
+# '$deps'. These are assumed to be git clones that do not need to be re-cloned
+# every time. Do a 'git clean' in each of them individually. If '$deps' is not
+# defined or the mentioned dirs do not exist, nothing special happens, so this
+# script can be safely run in any git clone in deeper subdirs of the workspace.
