+#!/bin/bash
+
+## This script replaces the default "erl" in erts-VSN/bin. This is necessary
+## as escript depends on erl and in turn, erl depends on having access to a
+## bootscript (start.boot). Note that this script is ONLY invoked as a side-effect
+## of running escript -- the embedded node bypasses erl and uses erlexec directly
+## (as it should).
+##
+## Note that this script makes the assumption that there is a start_clean.boot
+## file available in $ROOTDIR/release/VSN.
+
+# Determine the abspath of where this script is executing from.
+ERTS_BIN_DIR=$(cd ${0%/*} && pwd)
+
+# Now determine the root directory -- this script runs from erts-VSN/bin,
+# so we simply need to strip off two dirs from the end of the ERTS_BIN_DIR
+# path.
