## 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.
