+# Typical usage:
+# $ source "./with_oper_for_vpp.sh" "per_patch_perf.sh"
+#
+# This wrapper is mostly useful for Jenkins invocation,
+# because in manual testing people usually already have checked out
+# the branches they want to test (which might not yet be available in Gerrit).
+#
+# Assumptions:
+# + There is a directory holding initial CSIT code to use, this script is there.
+# + First argument is filename of next entry script to execute.
+#   TODO: Support relative paths? Relative to BASH_ENTRY_DIR?
+# Consequences:
+# + A csit branch name is computed.
+# + Possibly overriden, based on CSIT_REF value.
+# + The computed or overriden CSIT refspec is checked out.
+# + The argument entry script is sourced, with arguments shifted.
+
+# "set -eu" handles failures from the following two lines.
